PART I.


ITEM 1. BUSINESS

General

The Geodyne Energy Income Limited Partnership I-D (the "I-D Partnership"),
Geodyne Energy Income Limited Partnership I-E (the "I-E Partnership"), and
Geodyne Energy Income Limited Partnership I-F (the "I-F Partnership")
(collectively, the "Partnerships") are limited partnerships formed under the
Oklahoma Revised Uniform Limited Partnership Act. Each Partnership is composed
of public investors as limited partners (the "Limited Partners") and Geodyne
Resources, Inc. ("Geodyne"), a Delaware corporation, as the general partner. The
Partnerships commenced operations on the dates set forth below:

Date of
Partnership Activation
----------- ------------------

I-D March 4, 1986
I-E September 10, 1986
I-F December 16, 1986

Immediately following activation, each Partnership invested as a general
partner in a separate Oklahoma general partnership which actually conducts the
Partnerships' production operations. Geodyne serves as managing partner of such
general partnerships. Unless the context indicates otherwise, all references to
any single Partnership or all of the Partnerships in this Annual Report on Form
10-K ("Annual Report") are references to the Partnership and its related general
partnership, collectively. In addition, unless the context indicates otherwise,
all references to the "General Partner" in this Annual Report are references to
Geodyne as the general partner of the Partnerships, and as the managing partner
of the related general partnerships.

The General Partner currently serves as general partner of 26 limited
partnerships, including the Partnerships. The General Partner is a wholly-owned
subsidiary of Samson Investment Company. Samson Investment Company and its
various corporate subsidiaries, including the General Partner (collectively
"Samson"), are primarily engaged in the production and development of and
exploration for oil and gas reserves and the acquisition and operation of
producing properties. At December 31, 2004, Samson owned interests in
approximately 16,000 oil and gas wells located in 18 States of the United States
and the countries of Canada, Venezuela, and Australia. At December 31, 2004,
Samson operated approximately 5,000 oil and gas wells located in 14 states of
the United States, as well as Canada, Venezuela, and Australia.




-4-




The Partnerships are currently engaged in the business of owning interests
in producing oil and gas properties located in the continental United States.
The Partnerships may also engage to a limited extent in development drilling on
producing oil and gas properties as required for the prudent management of the
Partnerships.

As limited partnerships, the Partnerships have no officers, directors, or
employees. They rely instead on the personnel of the General Partner and Samson.
As of February 15, 2005, Samson employed approximately 1,100 persons. No
employees are covered by collective bargaining agreements, and management
believes that Samson provides a sound employee relations environment. For
information regarding the executive officers of the General Partner, see "Item
10. Directors and Executive Officers of the General Partner."

The General Partner's and the Partnerships' principal place of business is
located at Samson Plaza, Two West Second Street, Tulsa, Oklahoma 74103, and
their telephone number is (918) 583-1791 or (888) 436-3963 [(888) GEODYNE].

Pursuant to the terms of the partnership agreements for the Partnerships
(the "Partnership Agreements"), the Partnerships would have terminated on
December 31, 1999. However, the Partnership Agreements provide that the General
Partner may extend the term of each Partnership for up to five periods of two
years each. The General Partner has extended the terms of the Partnerships for
the third two-year extension period to December 31, 2005. As of the date of this
Annual Report, the General Partner has not determined whether to further extend
the term of any Partnership.


Funding

Although the Partnership Agreements permit each Partnership to incur
borrowings, operations and expenses are currently funded out of each
Partnership's revenues from oil and gas sales. The General Partner may, but is
not required to, advance funds to a Partnership for the same purposes for which
Partnership borrowings are authorized.


Principal Products Produced and Services Rendered

The Partnerships' sole business is the production of, and related
incidental development of, oil and gas. The Partnerships do not refine or
otherwise process crude oil and condensate. The Partnerships do not hold any
patents, trademarks, licenses, or concessions and are not a party to any
government contracts. The Partnerships have no backlog of orders and do not
participate in research and development activities. The Partnerships are not
presently encountering shortages of oilfield tubular goods,



-5-




compressors, production material, or other equipment. However, substantial
increases in the price of steel may increase the costs of any future workover,
recompletion or drilling activities conducted by the Partnerships.


Competition and Marketing

The primary source of liquidity and Partnership cash distributions comes
from the net revenues generated from the sale of oil and gas produced from the
Partnerships' oil and gas properties. The level of net revenues is highly
dependent upon the total volumes of oil and natural gas sold. Oil and gas
reserves are depleting assets and will experience production declines over time,
thereby likely resulting in reduced net revenues. The level of net revenues is
also highly dependent upon the prices received for oil and gas sales, which
prices have historically been very volatile and may continue to be so.
Additionally, lower oil and natural gas prices may reduce the amount of oil and
gas that is economic to produce and reduce the Partnerships' revenues and cash
flow. Various factors beyond the Partnerships' control will affect prices for
oil and natural gas, such as:

* Worldwide and domestic supplies of oil and natural gas;
* The ability of the members of the Organization of Petroleum Exporting
Countries ("OPEC") to agree upon and maintain oil prices and production
quotas;
* Political instability or armed conflict in oil-producing regions or
around major shipping areas;
* The level of consumer demand and overall economic activity;
* The competitiveness of alternative fuels;
* Weather conditions;
* The availability of pipelines for transportation; and
* Domestic and foreign government regulations and taxes.

It is not possible to predict the future direction of oil or natural gas
prices or whether the above discussed trends will remain. Operating costs,
including General and Administrative Expenses, may not decline over time or may
experience only a gradual decline, thus adversely affecting net revenues as
either production or oil and natural gas prices decline. In any particular
period, net revenues may also be affected by either the receipt of proceeds from
property sales or the incursion of additional costs as a result of well
workovers, recompletions, new well drilling, and other events.


Significant Customers

The following customers accounted for ten percent or more of the
Partnerships' oil and gas sales during the year ended December 31, 2004:



-6-






Partnership Customer Percentage
----------- -------- ----------

I-D Chevron U.S.A., Inc. ("Chevron") 29.3%
Duke Energy Field Services, Inc.
("Duke") 21.5%
Enogex Services Corporation 11.6%
Cinergy Marketing Company
("Cinergy") 11.4%

I-E Chevron 24.5%
BP America Production
Company ("BP") 12.4%
Duke 11.8%
Cinergy 11.4%

I-F Cinergy 16.9%
Duke 13.7%
BP 13.3%
Chevron 10.2%

In the event of interruption of purchases by one or more of the
Partnerships' significant customers or the cessation or material change in
availability of open access transportation by the Partnerships' pipeline
transporters, the Partnerships may encounter difficulty in marketing their gas
and in maintaining historic sales levels. Management does not expect any of its
open access transporters to seek authorization to terminate their transportation
services. Even if the services were terminated, management believes that
alternatives would be available whereby the Partnerships would be able to
continue to market their gas.

The Partnerships' principal customers for crude oil production are
refiners and other companies which have pipeline facilities near the producing
properties of the Partnerships. In the event pipeline facilities are not
conveniently available to production areas, crude oil is usually trucked by
purchasers to storage facilities.


Oil, Gas, and Environmental Control Regulations

Regulation of Production Operations -- The production of oil and gas is
subject to extensive federal and state laws and regulations governing a wide
variety of matters, including the drilling and spacing of wells, allowable rates
of production, prevention of waste and pollution, and protection of the
environment. In addition to the direct costs borne in complying with such
regulations, operations and revenues may be impacted to the extent that certain
regulations limit oil and gas production to below economic levels.




-7-




Regulation of Sales and Transportation of Oil and Gas -- Sales of crude
oil and condensate are made by the Partnerships at market prices and are not
subject to price controls. The sale of gas may be subject to both federal and
state laws and regulations. The provisions of these laws and regulations are
complex and affect all who produce, resell, transport, or purchase gas,
including the Partnerships. Although virtually all of the Partnerships' gas
production is not subject to price regulation, other regulations affect the
availability of gas transportation services and the ability of gas consumers to
continue to purchase or use gas at current levels. Accordingly, such regulations
may have a material effect on the Partnerships' operations and projections of
future oil and gas production and revenues.

Future Legislation -- Legislation affecting the oil and gas industry is
under constant review for amendment or expansion. Because such laws and
regulations are frequently amended or reinterpreted, management is unable to
predict what additional energy legislation may be proposed or enacted or the
future cost and impact of complying with existing or future regulations.

Regulation of the Environment -- The Partnerships' operations are subject
to numerous laws and regulations governing the discharge of materials into the
environment or otherwise relating to environmental protection. Compliance with
such laws and regulations, together with any penalties resulting from
noncompliance may increase the cost of the Partnerships' operations or may
affect the Partnerships' ability to timely complete existing or future
activities. Management anticipates that various local, state, and federal
environmental control agencies will have an increasing impact on oil and gas
operations.


Insurance Coverage

The Partnerships are subject to all of the risks inherent in the
exploration for and production of oil and gas, including blowouts, pollution,
fires, and other casualties. The Partnerships maintain insurance coverage as is
customary for entities of a similar size engaged in operations similar to that
of the Partnerships, but losses can occur from uninsurable risks or in amounts
in excess of existing insurance coverage. In particular, many types of pollution
and contamination can exist, undiscovered, for long periods of time and can
result in substantial environmental liabilities which are not insured. The
occurrence of an event which is not fully covered by insurance could have a
material adverse effect on the Partnerships' financial condition and results of
operations.

I-F 824 658 166 13.81 6.03 7.78

- ----------

(1) The designation of a well as an oil well or gas well is made by the General
Partner based on the relative amount of oil and gas reserves for the well.
Regardless of a well's oil or gas designation, it may produce oil, gas, or
both oil and gas.
(2) As used in this Annual Report, "gross well" refers to a well in which a
working interest is owned, accordingly, the number of gross wells is the
total number of wells in which a working interest is owned.
(3) As used in this Annual Report, "net well" refers to the sum of the
fractional working interests owned in gross wells. For example, a 15%
working interest in a well represents one gross well, but 0.15 net well.


Drilling Activities

During the year ended December 31, 2004, the Partnerships directly or
indirectly participated in the drilling activities described below:

Oil and Gas Production, Revenue, and Price History

The following tables set forth certain historical information concerning
the oil (including condensates) and gas production, net of all royalties,
overriding royalties, and other third party interests, of the Partnerships,
revenues attributable to such production, and certain price and cost
information. As used in the following tables, direct operating expenses include
lease operating expenses and production taxes. In addition, gas



-10-




production is converted to oil equivalents at the rate of six Mcf per barrel,
representing the estimated relative energy content of gas and oil, which rate is
not necessarily indicative of the relationship of oil and gas prices. The
respective prices of oil and gas are affected by market and other factors in
addition to relative energy content.

Proved Reserves and Net Present Value

The following table sets forth each Partnership's estimated proved oil and
gas reserves and net present value therefrom as of December 31, 2004. The
schedule of quantities of proved oil and gas reserves was prepared by the
General Partner in accordance with the rules prescribed by the Securities and
Exchange Commission (the "SEC"). Certain reserve information was reviewed by
Ryder Scott Company, L.P. ("Ryder Scott"), an independent petroleum engineering
firm. As used throughout this Annual Report, "proved reserves" refers to those
estimated quantities of crude oil, gas, and gas liquids which geological and
engineering data demonstrate with reasonable certainty to be recoverable in
future years from known oil and gas reservoirs under existing economic and
operating conditions.




-13-





Net present value represents estimated future gross cash flow from the
production and sale of proved reserves, net of estimated oil and gas production
costs (including production taxes, ad valorem taxes, and operating expenses) and
estimated future development costs, discounted at 10% per annum. Net present
value attributable to the Partnerships' proved reserves was calculated on the
basis of current costs and prices at December 31, 2004. Such prices were not
escalated except in certain circumstances where escalations were fixed and
readily determinable in accordance with applicable contract provisions. Oil and
gas prices at December 31, 2004 ($43.36 per barrel and $6.02 per Mcf,
respectively) were higher than the prices in effect on December 31, 2003 ($29.25
per barrel and $5.77 per Mcf, respectively). This increase in oil and gas prices
has caused the estimates of remaining economically recoverable reserves, as well
as the values placed on said reserves, at December 31, 2004 to be higher than
such estimates and values at December 31, 2003. The prices used in calculating
the net present value attributable to the Partnerships' proved reserves do not
necessarily reflect market prices for oil and gas production subsequent to
December 31, 2004. There can be no assurance that the prices used in calculating
the net present value of the Partnerships' proved reserves at December 31, 2004
will actually be realized for such production.

The process of estimating oil and gas reserves is complex, requiring
significant subjective decisions in the evaluation of available geological,
engineering, and economic data for each reservoir. The data for a given
reservoir may change substantially over time as a result of, among other things,
additional development activity, production history, and viability of production
under varying economic conditions; consequently, it is reasonably possible that
material revisions to existing reserve estimates may occur in the near future.
Although every reasonable effort has been made to ensure that these reserve
estimates represent the most accurate assessment possible, the significance of
the subjective decisions required and variances in available data for various
reservoirs make these estimates generally less precise than other estimates
presented in connection with financial statement disclosures.

Following is a description of those oil and gas properties whose revisions
in the estimated proved reserves (based on equivalent barrels of oil) as of
December 31, 2004, as compared to December 31, 2003, were significant to the
Partnerships.

The I-D, I-E, and I-F Partnerships' estimated proved reserves increased
approximately 15,000, 65,000, and 30,000 barrels of oil equivalent,
respectively, in the Jo-Mill Unit, which is a large unitized property in Borden
County, Texas from December 31, 2003 to December 31, 2004. This increase was
primarily due to the completion of several new wells in 2004 and a revised
forecast in reserves based on actual production experience.


Title to Oil and Gas Properties

Management believes that the Partnerships have satisfactory title to their
oil and gas properties. Record title to all of the Partnerships' properties is
held by either the Partnerships or Geodyne Nominee Corporation, an affiliate of
the General Partner.

Title to the Partnerships' properties is subject to customary royalty,
overriding royalty, carried, working, and other similar interests and
contractual arrangements customary in the oil and gas industry, to liens for
current taxes not yet due, and to other encumbrances. Management believes that
such burdens do not materially detract from the value of such properties or from
the Partnerships' interest therein or materially interfere with their use in the
operation of the Partnerships' business.


ITEM 3. LEGAL PROCEEDINGS

A lawsuit styled Xplor Energy Operating Co. v. The Newton Corp, et al.,
Case No. 99-04-01960-CV, 284th Judicial District Court of Montgomery County,
Texas was filed on May 12, 1999. The Newton Corp. ("Newton") acquired an
interest at auction in the State 87-S1 (the "Well") owned by the I-E
Partnership, the I-F Partnership, and a related partnership (collectively the
"Prior Owners"). Eight months after Newton's acquisition of the Prior Owners'
interest, the operator of the Well, Xplor Energy Operating Co. ("Xplor"),
plugged and abandoned the Well. Xplor filed this lawsuit on May 12, 1999
alleging that the Prior Owners were the record owners of the lease when it
expired and that the Prior Owners were responsible for the costs of plugging and
abandoning the Well. Xplor sought to recover the Prior Owners' proportionate
share of the costs to plug and abandon the well along with attorneys' fees and
interest. The Prior Owners denied liability and cross-claimed against Newton for
indemnity for any amounts that may be awarded to Xplor. Newton in turn alleged
that the Prior Owners were liable for the plugging costs. Trial was held on
August 6, 2001. At the conclusion of the trial the



-18-




Court awarded Xplor $86,000 plus $200,000 in attorney fees and awarded Newton
$300 plus $161,000 in attorney fees to be divided among the Prior Owners. On
January 15, 2002 the Prior Owners filed an appeal of the matter with the Court
of Appeals, Fifth District of Texas, Dallas, Texas, Case No. 05-02-00070-CV. The
I-E Partnership and I-F Partnership have approximately 50% and 35%,
respectively, of the liability with respect to the trial court judgment rendered
in the matter.

On April 23, 2002 the Prior Owners entered into a settlement agreement
with Xplor thereby settling for $165,000 the judgment in favor of Xplor. On
January 23, 2003 the Court of Appeals ruled against Newton on all issues except
the one claim resulting in the $300 liability to the Prior Owners, and remanded
the case to the trial court to determine and award to Newton any portion of the
alleged attorneys' fees awarded to them that is attributable solely to the $300
award against the Prior Owners. The Prior Owners requested the Texas Supreme
Court to reverse this decision as to the $300 claim and its related attorneys'
fees. The Texas Supreme Court initially declined to consider this request, but
in October 2004 entertained oral arguments on the matter. A decision is expected
in 2005.

Except as described above, to the knowledge of the General Partner,
neither the General Partner nor the Partnerships or their properties are subject
to any litigation, the results of which would have a material effect on the
Partnerships' or the General Partner's financial condition or operations.


ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF LIMITED PARTNERS

There were no matters submitted to a vote of the Limited Partners of any
Partnership during 2004.


PART II.

ITEM 5. MARKET FOR UNITS AND RELATED LIMITED PARTNER MATTERS

As of March 3, 2005, the number of Units outstanding and the approximate
number of Limited Partners of record in the Partnerships were as follows:

Number of
Number of Limited
Partnership Units Partners
----------- --------- ---------
I-D 7,195 590
I-E 41,839 2,240
I-F 14,321 690

Units were initially sold for a price of $1,000. The Units are not traded
on any exchange and there is no public trading



-19-




market for them. The General Partner is aware of certain transfers of Units
between unrelated parties, some of which are facilitated by secondary trading
firms and matching services. In addition, as further described below, the
General Partner is aware of certain "4.9% tender offers" which have been made
for the Units. The General Partner believes that the transfers between unrelated
parties have been limited and sporadic in number and volume. Other than trades
facilitated by certain secondary trading firms and matching services, no
organized trading market for Units exists and none is expected to develop. Due
to the nature of these transactions, the General Partner has no verifiable
information regarding prices at which Units have been transferred. Further, a
transferee may not become a substitute Limited Partner without the consent of
the General Partner.

Pursuant to the terms of the Partnership Agreements, the General Partner
is obligated to annually issue a repurchase offer which is based on the
estimated future net revenues from the Partnerships' reserves and is calculated
pursuant to the terms of the Partnership Agreements. Such repurchase offer is
recalculated monthly in order to reflect cash distributions to the Limited
Partners and extraordinary events. The following table sets forth the General
Partner's repurchase offer per Unit as of the periods indicated. For purpose of
this Annual Report, a Unit represents an initial subscription of $1,000 to a
Partnership.

The Partnership Agreements also provide for a right of presentment ("Right
of Presentment") whereby the General Partner is required, upon request, to
purchase up to 10% of a Partnership's outstanding Units at a price calculated
pursuant to the terms of the Partnership Agreements and based on the liquidation
value of the limited partnership interest, with a reduction for 70% of cash
distributions that have been received prior to the transfer of the partnership
interest. The following table sets forth the Right of Presentment price per Unit
as of the periods indicated.

In addition to the repurchase offer and Right of Presentment described
above, some of the Partnerships have been subject to "4.9% tender offers" from
several third parties. The General Partner does not know the terms of these
offers or the prices received by the Limited Partners who accepted these offers.


Cash Distributions

Cash distributions are primarily dependent upon a Partnership's cash
receipts from the sale of oil and gas production and cash requirements of the
Partnership. Distributable cash is determined by the General Partner at the end
of each calendar quarter and distributed to the Limited Partners within 45 days
after the end of the quarter. Distributions are restricted to cash on hand less
amounts required to be retained out of such cash as determined in the sole
judgment of the General Partner to pay costs, expenses, or other Partnership
obligations whether accrued or anticipated to accrue. In certain instances, the
General Partner may not distribute the full amount of cash receipts which might
otherwise be available for distribution in an effort to equalize or stabilize
the amounts of quarterly distributions. Any available amounts not distributed
are invested and the interest or income thereon is for the accounts of the
Limited Partners.

The following is a summary of cash distributions paid to the Limited
Partners during 2003 and 2004 and the first quarter of 2005:

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS

Use of Forward-Looking Statements and Estimates

This Annual Report contains certain forward-looking statements. The words
"anticipate," "believe," "expect," "plan," "intend," "estimate," "project,"
"could," "may," and similar expressions are intended to identify forward-looking
statements. Such statements reflect management's current views with respect to
future events and financial performance. This Annual Report also includes
certain information which is, or is based upon, estimates and assumptions. Such
estimates and assumptions are management's efforts to accurately reflect the
condition and operation of the Partnerships.

Use of forward-looking statements and estimates and assumptions involve
risks and uncertainties which include, but are not limited to, the volatility of
oil and gas prices, the uncertainty of reserve information, the operating risk
associated with oil and gas properties (including the risk of personal injury,
death, property damage, damage to the well or producing reservoir, environmental
contamination, and other operating risks), the prospect of changing tax and
regulatory laws, the availability and capacity of processing and transportation
facilities, the general economic climate, the supply and price of foreign
imports of oil and gas, the level of consumer product demand, and the price and
availability of alternative fuels. Should one or more of these risks or
uncertainties occur or should estimates or underlying assumptions prove
incorrect, actual conditions or results may vary materially and adversely from
those stated, anticipated, believed, estimated, or otherwise indicated.


General Discussion

The following general discussion should be read in conjunction with the
analysis of results of operations provided below. The primary source of
liquidity and Partnership cash distributions comes from the net revenues
generated from the sale of oil and gas produced from the Partnerships' oil and
gas properties. The level of net revenues is highly dependent upon the prices
received for oil and gas sales, which prices have historically been very
volatile and may continue to be so. Additionally, lower oil and natural gas
prices may reduce the amount of oil and gas that is economic to produce and
reduce the Partnerships' revenues and cash flow. Various factors beyond the
Partnerships' control will affect prices for oil and natural gas, such as:



-26-





* Worldwide and domestic supplies of oil and natural gas;
* The ability of the members of the Organization of Petroleum Exporting
Countries ("OPEC") to agree upon and maintain oil prices and production
quotas;
* Political instability or armed conflict in oil-producing regions or
around major shipping areas;
* The level of consumer demand and overall economic activity;
* The competitiveness of alternative fuels;
* Weather conditions;
* The availability of pipelines for transportation; and
* Domestic and foreign government regulations and taxes.

It is not possible to predict the future direction of oil or natural gas
prices or whether the above discussed trends will remain. Operating costs,
including General and Administrative Expenses, may not decline over time or may
experience only a gradual decline, thus adversely affecting net revenues as
either production or oil and natural gas prices decline. In any particular
period, net revenues may also be affected by either the receipt of proceeds from
property sales or the incursion of additional costs as a result of well
workovers, recompletions, new well drilling, and other events.

In addition to pricing, the level of net revenues is also highly dependent
upon the total volumes of oil and natural gas sold. Oil and gas reserves are
depleting assets and will experience production declines over time, thereby
likely resulting in reduced net revenues. Despite this general trend of
declining production, several factors can cause the volumes of oil and gas sold
to increase or decrease at an even greater rate over a given period. These
factors include, but are not limited to, (i) geophysical conditions which cause
an acceleration of the decline in production, (ii) the shutting in of wells (or
the opening of previously shut-in wells) due to low oil and gas prices (or high
oil and gas prices), mechanical difficulties, loss of a market or
transportation, or performance of workovers, recompletions, or other operations
in the well, (iii) prior period volume adjustments (either positive or negative)
made by purchasers of the production, (iv) ownership adjustments in accordance
with agreements governing the operation or ownership of the well (such as
adjustments that occur at payout), and (v) completion of enhanced recovery
projects which increase production for the well. Many of these factors are very
significant as related to a single well or as related to many wells over a short
period of time. However, due to the large number of wells owned by the
Partnerships, these factors are generally not material as compared to the normal
decline in production experienced on all remaining wells.

Results of Operations

An analysis of the change in net oil and gas operations (oil and gas
sales, less lease operating expenses and production taxes) is presented in the
tables following "Results of Operations" under the heading "Average Sales
Prices, Production Volumes, and Average Production Costs." Following is a
discussion of each Partnership's results of operations for the year ended
December 31, 2004 as compared to the year ended December 31, 2003 and for the
year ended December 31, 2003 as compared to the year ended December 31, 2002.


I-D Partnership
---------------

Year Ended December 31, 2004 Compared
to Year Ended December 31, 2003
-------------------------------------

Total oil and gas sales decreased $76,381 (7.6%) in 2004 as compared to
2003. Of this decrease, approximately $8,000 and $164,000, respectively, were
related to decreases in volumes of oil and gas sold. These decreases were
partially offset by increases of approximately $39,000 and $57,000,
respectively, related to increases in the average prices of oil and gas sold.
Volumes of oil and gas sold decreased 294 barrels and 32,913 Mcf, respectively,
in 2004 as compared to 2003. The decrease in volumes of gas sold was primarily
due to (i) normal declines in production and (ii) the shutting-in of one
significant well during 2004 in order to perform a workover. As of the date of
this Annual Report, the operator has not determined when the shut-in well will
return to production. Average oil and gas prices increased to $40.06 per barrel
and $5.38 per Mcf, respectively, in 2004 from $28.87 per barrel and $4.99 per
Mcf, respectively, in 2003.

Oil and gas production expenses (including lease operating expenses and
production taxes) decreased $13,972 (7.6%) in 2004 as compared to 2003. As a
percentage of oil and gas sales, these expenses remained constant at 18.3% in
2004 and 2003.

Depreciation, depletion, and amortization of oil and gas properties
decreased $39,268 (54.1%) in 2004 as compared to 2003. This decrease was
primarily due to (i) one significant well being fully depleted in 2003 due to
the lack of remaining reserves and (ii) the decreases in volumes of oil and gas
sold. These decreases were partially offset by several other wells being fully
depleted in 2004 due to the lack of remaining reserves. As a percentage of oil
and gas sales, this expense decreased to 3.6% in 2004 from 7.2% in 2003. This
percentage decrease was primarily due to the dollar decrease in depreciation,
depletion, and amortization of oil and gas properties.




-28-




General and administrative expenses remained relatively constant in 2004
and 2003. As a percentage of oil and gas sales, these expenses increased to
11.4% in 2004 from 10.5% in 2003.

The Limited Partners have received cash distributions through December 31,
2004 totaling $17,269,175 or 240.03% of Limited Partners' capital contributions.


Year Ended December 31, 2003 Compared
to Year Ended December 31, 2002
-------------------------------------

Total oil and gas sales increased $286,022 (39.6%) in 2003 as compared to
2002. Of this increase, approximately $409,000 was related to an increase in the
average price of gas sold, which increase was partially offset by a decrease of
approximately $141,000 related to a decrease in volumes of gas sold. Volumes of
oil sold increased 102 barrels, while volumes of gas sold decreased 51,863 Mcf,
respectively, in 2003 as compared to 2002. The decrease in volumes of gas sold
was primarily due to (i) normal declines in production, (ii) a positive prior
period volume adjustment on one significant well during 2002, and (iii) a
positive prior period gas balancing adjustment on another significant well
during 2002. Average oil and gas prices increased to $28.87 per barrel and $4.99
per Mcf, respectively, in 2003 from $24.79 per barrel and $2.72 per Mcf,
respectively, in 2002.

Oil and gas production expenses (including lease operating expenses and
production taxes) decreased $8,657 (4.5%) in 2003 as compared to 2002. This
decrease was primarily due to a decrease in lease operating expenses associated
with the decrease in volumes of gas sold, which decrease was partially offset by
an increase in production taxes associated with the increase in oil and gas
sales. As a percentage of oil and gas sales, these expenses decreased to 18.3%
in 2003 from 26.8% in 2002. This percentage decrease was primarily due to the
increases in the average prices of oil and gas sold.

Depreciation, depletion, and amortization of oil and gas properties
increased $37,108 (104.6%) in 2003 as compared to 2002. This increase was
primarily due to one significant well being fully depleted in 2003 due to the
lack of remaining economically recoverable reserves, which increase was
partially offset by upward revisions in the estimates of remaining oil and gas
reserves at December 31, 2003. As a percentage of oil and gas sales, this
expense increased to 7.2% in 2003 from 4.9% in 2002. This percentage increase
was primarily due to the dollar increase in depreciation, depletion, and
amortization of oil and gas properties.

General and administrative expenses increased $2,262 (2.2%) in 2003 as
compared to 2002. As a percentage of oil and gas



-29-




sales, these expenses decreased to 10.5% in 2003 from 14.3% in 2002. This
percentage decrease was primarily due to the increase in oil and gas sales.



I-E Partnership
---------------

Year Ended December 31, 2004 Compared
to Year Ended December 31, 2003
-------------------------------------

Total oil and gas sales decreased $329,122 (5.2%) in 2004 as compared to
2003. Of this decrease, approximately $242,000 and $810,000, respectively, were
related to decreases in volumes of oil and gas sold. These decreases were
partially offset by increases of approximately $446,000 and $277,000,
respectively, related to increases in the average prices of oil and gas sold.
Volumes of oil and gas sold decreased 8,766 barrels and 165,627 Mcf,
respectively, in 2004 as compared to 2003. The decrease in volumes of oil sold
was primarily due to (i) normal declines in production and (ii) a positive prior
period volume adjustment made by the operator on one significant well during
2003. The decrease in volumes of gas sold was primarily due to (i) normal
declines in production and (ii) the shutting-in of one significant well during
2004 in order to perform a workover. As of the date of this Annual Report, the
operator has not determined when the shut-in well will return to production.
Average oil and gas prices increased to $37.56 per barrel and $5.23 per Mcf,
respectively, in 2004 from $27.57 per barrel and $4.89 per Mcf, respectively, in
2003.

Oil and gas production expenses (including lease operating expenses and
production taxes) remained relatively constant in 2004 and 2003. A decrease in
lease operating expenses associated with the decreases in volumes of oil and gas
sold was substantially offset by (i) workover expenses incurred on several wells
during 2004 and (ii) repair and maintenance expenses incurred on another
significant well during 2004. As a percentage of oil and gas sales, these
expenses increased to 23.6% in 2004 from 22.5% in 2003.

Depreciation, depletion, and amortization of oil and gas properties
decreased $290,890 (59.8%) in 2004 as compared to 2003. This decrease was
primarily due to (i) one significant well being fully depleted in 2003 due to
the lack of remaining reserves and (ii) the decreases in volumes of oil and gas
sold. These decreases were partially offset by several other wells being fully
depleted in 2004 due to the lack of remaining reserves. As a percentage of oil
and gas sales, this expense decreased to 3.3% in 2004 from 7.7% in 2003. This
percentage decrease was primarily due to the dollar decrease in



-30-




depreciation, depletion, and amortization of oil and gas properties.

General and administrative expenses remained relatively constant in 2004
and 2003. As a percentage of oil and gas sales, these expenses increased to 8.5%
in 2004 from 8.2% in 2003.

The Limited Partners have received cash distributions through December 31,
2004 totaling $71,250,552 or 170.30% of Limited Partners' capital contributions.


Year Ended December 31, 2003 Compared
to Year Ended December 31, 2002
-------------------------------------

Total oil and gas sales increased $1,836,836 (41.4%) in 2003 as compared
to 2002. Of this increase, approximately $254,000 and $2,144,000, respectively,
were related to increases in the average prices of oil and gas sold. These
increases were partially offset by a decrease of approximately $690,000 related
to a decrease in volumes of gas sold. Volumes of oil sold increased 5,598
barrels, while volumes of gas sold decreased 254,479 Mcf, respectively, in 2003
as compared to 2002. The increase in volumes of oil sold was primarily due to
(i) an increase in production during 2003 on one significant well due to the
successful recompletion of that well in mid 2002 and (ii) a positive prior
period volume adjustment made by the purchaser on another significant well in
2003. The decrease in volumes of gas sold was primarily due to (i) normal
declines in production, (ii) a positive prior period volume adjustment on one
significant well in 2002, and (iii) a positive prior period gas balancing
adjustment on another significant well in 2002. Average oil and gas prices
increased to $27.57 per barrel and $4.89 per Mcf, respectively, in 2003 from
$22.80 per barrel and $2.71 per Mcf, respectively, in 2002.

Oil and gas production expenses (including lease operating expenses and
production taxes) increased $35,896 (2.6%) in 2003 as compared to 2002. This
increase was primarily due to (i) an increase in production taxes associated
with the increase in oil and gas sales, (ii) a partial reversal in 2002 of
approximately $75,000 (due to a partial post-judgment settlement) of a charge
previously accrued for this judgment, and (iii) workover expenses incurred on
one significant well during 2003. These increases were partially offset by (i) a
decrease in lease operating expenses associated with the decrease in volumes of
gas sold and (ii) workover expenses incurred on one significant well during
2002. As a percentage of oil and gas sales, these expenses decreased to 22.5% in
2003 from 31.0% in 2002. This percentage decrease was primarily due to the
increases in the average prices of oil and gas sold.




-31-




Depreciation, depletion, and amortization of oil and gas properties
increased $240,889 (98.1%) in 2003 as compared to 2002. This increase was
primarily due to one significant well being fully depleted in 2003 due to the
lack of remaining economically recoverable reserves, which increase was
partially offset by upward revisions in the estimates of remaining oil and gas
reserves at December 31, 2003. As a percentage of oil and gas sales, this
expense increased to 7.7% in 2003 from 5.5% in 2002. This percentage increase
was primarily due to the dollar increase in depreciation, depletion, and
amortization of oil and gas properties.

General and administrative expenses remained relatively constant in 2003
and 2002. As a percentage of oil and gas sales, these expenses decreased to 8.2%
in 2003 from 11.4% in 2002. This percentage decrease was primarily due to the
increase in oil and gas sales.


I-F Partnership

Year Ended December 31, 2004 Compared
to Year Ended December 31, 2003
-------------------------------------

Total oil and gas sales increased $40,759 (2.1%) in 2004 as compared to
2003. Of this increase, approximately $200,000 and $92,000, respectively, were
related to increases in the average prices of oil and gas sold. These increases
were partially offset by decreases of approximately $111,000 and $140,000,
respectively, related to decreases in volumes of oil and gas sold. Volumes of
oil and gas sold decreased 4,007 barrels and 27,549 Mcf, respectively, in 2004
as compared to 2003. The decrease in volumes of oil sold was primarily due to
(i) normal declines in production and (ii) positive prior period volume
adjustments made by the operators on several wells during 2003. The decrease in
volumes of gas sold was primarily due to normal declines in production. This
decrease was partially offset by a negative prior period volume adjustment made
by the operator on one significant well during 2003. Average oil and gas prices
increased to $37.79 per barrel and $5.48 per Mcf, respectively, in 2004 from
$27.79 per barrel and $5.08 per Mcf, respectively, in 2003.

Oil and gas production expenses (including lease operating expenses and
production taxes) increased $33,502 (6.2%) in 2004 as compared to 2003. This
increase was primarily due to (i) workover expenses incurred on several wells
during 2004 and (ii) repair and maintenance expenses incurred on another
significant well during 2004. These increases were partially offset by a
decrease in lease operating expenses associated with the decreases in volumes of
oil and gas sold. As a percentage of oil



-32-




and gas sales, these expenses increased to 28.6% in 2004 from 27.5% in 2003.

Depreciation, depletion, and amortization of oil and gas properties
decreased $12,847 (15.8%) in 2004 as compared to 2003. This decrease was
primarily due to (i) the decreases in volumes of oil and gas sold and (ii) an
increase in depletable oil and gas properties in 2003 primarily due to
recompletion activities on one significant well. As a percentage of oil and gas
sales, this expense decreased to 3.4% in 2004 from 4.1% in 2003. This percentage
decrease was primarily due to the dollar decrease in depreciation, depletion,
and amortization of oil and gas properties.

General and administrative expenses remained relatively constant in 2004
and 2003. As a percentage of oil and gas sales, these expenses decreased to 9.4%
in 2004 from 9.6% in 2003.

The Limited Partners have received cash distributions through December 31,
2004 totaling $22,393,664 or 156.37% of Limited Partners' capital contributions.


Year Ended December 31, 2003 Compared
to Year Ended December 31, 2002
-------------------------------------

Total oil and gas sales increased $602,461 (44.1%) in 2003 as compared to
2002. Of this increase, approximately $127,000 and $577,000, respectively, were
related to increases in the average prices of oil and gas sold. These increases
were partially offset by a decrease of approximately $131,000 related to a
decrease in volumes of gas sold. Volumes of oil sold increased 1,280 barrels,
while volumes of gas sold decreased 46,337 Mcf, respectively, in 2003 as
compared to 2002. The decrease in volumes of gas sold was primarily due to (i)
normal declines in production, (ii) a positive prior period gas balancing
adjustment on one significant well in 2002, and (iii) a negative prior period
volume adjustment made by the purchaser on another significant well in 2003.
Average oil and gas prices increased to $27.79 per barrel and $5.08 per Mcf,
respectively, in 2003 from $22.47 per barrel and $2.83 per Mcf, respectively, in
2002.

Oil and gas production expenses (including lease operating expenses and
production taxes) increased $15,284 (2.9%) in 2003 as compared to 2002. This
increase was primarily due to (i) a partial reversal in 2002 of approximately
$52,000 (due to a partial post-judgment settlement) of a charge previously
accrued for this judgment and (ii) an increase in production taxes associated
with the increase in oil and gas sales. These increases were partially offset by
a decrease in lease operating expenses associated with the decrease in volumes
of gas sold. As a percentage of oil and gas sales, these expenses decreased to



-33-




27.5% in 2003 from 38.5% in 2002. This percentage decrease was primarily due to
the increases in the average prices of oil and gas sold.

Depreciation, depletion, and amortization of oil and gas properties
increased $13,000 (19.0%) in 2003 as compared to 2002. This increase was
primarily due to an increase in depletable oil and gas properties primarily due
to recompletion activities on one significant well during 2003. As a percentage
of oil and gas sales, this expense decreased to 4.1% in 2003 from 5.0% in 2002.
This percentage decrease was primarily due to the increases in average prices of
oil and gas sold.

General and administrative expenses increased $2,587 (1.4%) in 2003 as
compared to 2002. As a percentage of oil and gas sales, these expenses decreased
to 9.6% in 2003 from 13.7% in 2002. This percentage decrease was primarily due
to the increase in oil and gas sales.


Average Sales Prices, Production Volumes and Average Production Costs

The following tables are comparisons of the annual average oil and gas
sales prices, production volumes, and average production costs (lease operating
expenses and production taxes) per barrel of oil equivalent (one barrel of oil

Liquidity and Capital Resources

Net proceeds from operations less necessary operating capital are
distributed to the Limited Partners on a quarterly basis. See "Item 5. Market
for Units and Related Limited Partner Matters." The net proceeds from production
generally are not reinvested in productive assets, except to the extent that
producing wells are improved, where methods are employed to permit more
efficient recovery of reserves, or where identified developmental drilling or
recompletion opportunities are pursued, thereby resulting in a positive economic
impact. Assuming 2004



-36-




production levels for future years, the Partnerships' proved reserve quantities
at December 31, 2004 would have the following remaining lives:

Partnership Gas-Years Oil-Years
----------- --------- ---------

I-D 10.3 20.5
I-E 9.9 11.2
I-F 10.5 12.0

These life of reserves estimates are based on the current estimates of remaining
oil and gas reserves. See "Item 2. Properties" for a discussion of these reserve
estimates. Any increase or decrease in the oil and gas prices at December 31,
2004 may cause an increase or decrease in the estimated life of said reserves.

The Partnerships' available capital from the Limited Partners'
subscriptions has been spent on oil and gas properties and there should be no
further material capital resource commitments for any of the Partnerships in the
future. The Partnerships have no debt commitments. Cash for operational purposes
will be provided by current oil and gas production. During 2004, 2003, and 2002,
the Partnerships expended no capital on oil and gas acquisition or exploration
activities. However, during those years the Partnerships expended the following
amounts on oil and gas developmental activities, primarily well recompletion and
developmental drilling:

Partnership 2004 2003 2002
----------- -------- -------- --------

I-D $ 22,991 $ 39,589 $ 18,908
I-E 116,369 201,567 169,433
I-F 57,596 92,849 68,426

While these expenditures may reduce or eliminate cash available for a particular
quarterly cash distribution, the General Partner believes that these activities
are necessary for the prudent operation of the properties and maximization of
their value to the Partnerships.

The Partnerships sold certain oil and gas properties during 2004, 2003,
and 2002. The sale of the Partnerships' properties was made by the General
Partner after giving due consideration to both the offer price and the General
Partner's estimate of the property's remaining proved reserves and future
operating costs. Net proceeds from the sale of any such properties were included
in the calculation of the Partnerships' cash distributions for the quarter
immediately following the Partnerships' receipt of the proceeds. The amount of
such proceeds from the sales of oil and gas properties during 2004, 2003, and
2002, were as follows:




-37-





Partnership 2004 2003 2002
----------- ------ ------- --------

I-D $ 917 $ 101 $ 50,469
I-E 8,922 27,972 165,692
I-F 2,453 20,097 57,889

Over the years, as part of the normal course of business, some of the
Partnerships' interests in wells have been sold, generally at oil and gas
auctions. Given the generally favorable current environment for oil and gas
dispositions, it is possible that the number of and value of properties
considered for sale may increase. In the event of sales, any net proceeds are
distributed as soon as possible after the disposition. Future production, costs,
and cash flow will be reduced as properties are sold.

There can be no assurance as to the amount of the Partnerships' future
cash distributions. The Partnerships' ability to make cash distributions depends
primarily upon the level of available cash flow generated by the Partnerships'
operating activities, which will be affected (either positively or negatively)
by many factors beyond the control of the Partnerships, including the price of
and demand for oil and gas and other market and economic conditions. Even if
prices and costs remain stable, the amount of cash available for distributions
will decline over time (as the volume of production from producing properties
declines) since the Partnerships are not generally replacing production through
acquisitions of producing properties and extensive drilling.

The General Partner expects general and administrative expenses to
increase substantially during 2005 and 2006 due to costs required to comply with
Section 404 of the Sarbanes-Oxley Act of 2002. Such anticipated increase will
reduce cash available for distribution. The General Partner expects at least a
portion of this anticipated increase in general and administrative expenses to
continue in years beyond 2006.

Pursuant to the terms of the Partnership Agreements, the Partnerships
would have terminated on December 31, 1999. However, the Partnership Agreements
provide that the General Partner may extend the term of each Partnership for up
to five periods of two years each. The General Partner has extended the terms of
the Partnerships for the third two-year extension period to December 31, 2005.
As of the date of this Annual Report, the General Partner has not determined
whether to further extend the term of any Partnership.

Off-Balance Sheet Arrangements

The Partnerships do not have any off-balance sheet arrangements.


Tabular Disclosure of Contractual Obligations

The Partnerships do not have any contractual obligations of the type
required to be disclosed under this heading.


Critical Accounting Policies

The Partnerships follow the successful efforts method of accounting for
their oil and gas properties. Under the successful efforts method, the
Partnerships capitalize all property acquisition costs and development costs
incurred in connection with the further development of oil and gas reserves.
Property acquisition costs include costs incurred by the Partnerships or the
General Partner to acquire producing properties, including related title
insurance or examination costs, commissions, engineering, legal and accounting
fees, and similar costs directly related to the acquisitions, plus an allocated
portion of the General Partners' property screening costs. The acquisition cost
to the Partnership of properties acquired by the General Partner is adjusted to
reflect the net cash results of operations, including interest incurred to
finance the acquisition, for the period of time the properties are held by the
General Partner.

Depletion of the cost of producing oil and gas properties, amortization of
related intangible drilling and development costs, and depreciation of tangible
lease and well equipment are computed on the units-of-production method. The
Partnerships' calculation of depreciation, depletion, and amortization includes
estimated dismantlement and abandonment costs, net of estimated salvage values.
When complete units of depreciable property are retired or sold, the asset cost
and related accumulated depreciation are eliminated with any gain or loss
reflected in income. When less than complete units of depreciable property are
retired or sold, the proceeds are credited to oil and gas properties.

The Partnerships evaluate the recoverability of the carrying costs of
their proved oil and gas properties for each oil and gas field (rather than
separately for each well). If the unamortized costs of oil and gas properties
within a field exceed the expected undiscounted future cash flows from such
properties, the cost of the properties is written down to fair value, which is
determined by using the discounted future cash flows from the properties. The
risk that the Partnerships will be required to record impairment provisions in
the future increases as oil and gas prices decrease.



-39-




The Deferred Charge on the Balance Sheets included in Item 8 of this
Annual Report represents costs deferred for lease operating expenses incurred in
connection with the Partnerships' underproduced gas imbalance positions.
Conversely, the Accrued Liability represents charges accrued for lease operating
expenses incurred in connection with the Partnerships' overproduced gas
imbalance positions. The rate used in calculating the Deferred Charge and
Accrued Liability is the annual average production costs per Mcf.

The Partnerships' oil and condensate production is sold, title passed, and
revenue recognized at or near the Partnerships' wells under short-term purchase
contracts at prevailing prices in accordance with arrangements which are
customary in the oil and gas industry. Sales of gas applicable to the
Partnerships' interest in producing oil and gas leases are recorded as revenue
when the gas is metered and title transferred pursuant to the gas sales
contracts covering the Partnerships' interest in gas reserves. During such times
as a Partnership's sales of gas exceed its pro rata ownership in a well, such
sales are recorded as revenues unless total sales from the well have exceeded
the Partnership's share of estimated total gas reserves underlying the property,
at which time such excess is recorded as a liability. The rates per Mcf used to
calculate this liability are based on the average gas price for which the
Partnerships are currently settling this liability. These amounts were recorded
as gas imbalance payables in accordance with the sales method. These gas
imbalance payables will be settled by either gas production by the underproduced
party in excess of current estimates of total gas reserves for the well or by a
negotiated or contractual payment to the underproduced party.

In July 2001, the FASB issued FAS No. 143, "Accounting for Asset
Retirement Obligations", which is effective for fiscal years beginning after
June 15, 2002 (January 1, 2003 for the Partnerships). On January 1, 2003, the
Partnerships adopted FAS No. 143 and recorded an increase in capitalized cost of
oil and gas properties, an increase (decrease) in net income for the cumulative
effect of the change in accounting principle, and an asset retirement obligation
in the following approximate amounts for each Partnership:

Increase in Increase (Decrease)
Capitalized in Net Income for
Cost of Oil the Change in Asset
and Gas Accounting Retirement
Partnership Properties Principle Obligation
- ----------- ------------ ------------------ ----------

I-D $ 30,000 $1,000 $ 29,000
I-E 278,000 4,000 274,000
I-F 119,000 ( 300) 119,000




-40-




The asset retirement obligation is adjusted upwards each quarter in order
to recognize accretion of the time-related discount factor. For the year ended
December 31, 2004, the I-D, I-E, and I-F Partnerships recognized approximately
$2,000, $25,000, and $15,000, respectively, of an increase in depreciation,
depletion, and amortization expense, which was comprised of accretion of the
asset retirement obligation and depletion of the increase in capitalized cost of
oil and gas properties.


New Accounting Pronouncements

The Partnerships are not aware of any recently issued accounting
pronouncements that would have an impact on the Partnerships' future results of
operations and financial position.


Inflation and Changing Prices

Prices obtained for oil and gas production depend upon numerous factors,
including the extent of domestic and foreign production, foreign imports of oil,
market demand, domestic and foreign economic conditions in general, and
governmental regulations and tax laws. The general level of inflation in the
economy did not have a material effect on the operations of the Partnerships in
2004. Oil and gas prices have fluctuated during recent years and generally have
not followed the same pattern as inflation. See "Item 2. Properties - Oil and
Gas Production, Revenue, and Price History."


ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

The Partnerships do not hold any market risk sensitive instruments.


ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

The financial statements and supplementary data are indexed in Item 15
hereof.


ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND
FINANCIAL DISCLOSURE

None.

ITEM 9A. CONTROLS AND PROCEDURES

As of the end of this period covered by this report, the principal
executive officer and principal financial officer conducted an evaluation of the
Partnerships' disclosure controls and procedures (as defined in Rules 13a-15(e)
and 15d-15(e) under the Securities and Exchange Act of 1934). Based on this
evaluation, such officers concluded that the Partnerships' disclosure controls
and procedures are effective to ensure that information required to be disclosed
by the Partnerships in reports filed under the Exchange Act is recorded,
processed, summarized, and reported accurately and within the time periods
specified in the Securities and Exchange Commission rules and forms.


ITEM 9B. OTHER INFORMATION

The General Partner is not aware of any information required to be
reported on Form 8-K during the fourth quarter of 2004 but which was not so
reported.

2004 of reports required under Section 16 of the Securities Exchange Act of
1934.


Audit Committee Financial Expert

The Partnerships are not required by SEC regulations or otherwise to
maintain an audit committee. The board of directors of the General Partner
consists of one person and therefore serves as its audit committee. There is not
an audit committee financial expert, as defined in the SEC regulations, serving
on the General Partner's board of directors.


Code of Ethics

The General Partner has adopted a Code of Ethics which applies to all of
its executive officers, including those persons who perform the functions of
principal executive officer, principal financial officer, and principal
accounting officer. The Partnerships will provide, free of charge, a copy of
this Code of Ethics to any person upon receipt of a written request mailed to
Geodyne Resources, Inc., Investor Services, Samson Plaza, Two West 2nd Street,
Tulsa, OK 74103. Such request must include the address to which the Code of
Ethics should be mailed.


ITEM 11. EXECUTIVE COMPENSATION

The General Partner and its affiliates are reimbursed for actual general
and administrative costs and operating costs incurred and attributable to the
conduct of the business affairs and operations of the Partnerships, computed on
a cost basis, determined in accordance with generally accepted accounting
principles. Such reimbursed costs and expenses allocated to the Partnerships
include office rent, secretarial, employee



-43-




compensation and benefits, travel and communication costs, fees for professional
services, and other items generally classified as general or administrative
expense. When actual costs incurred benefit other Partnerships and affiliates,
the allocation of costs is based on the relationship of the Partnerships'
reserves to the total reserves owned by all Partnerships and affiliates. The
amount of general and administrative expense allocated to the General Partner
and its affiliates which was charged to each Partnership for 2004, 2003, and
2002, is set forth in the table below. Although the actual costs incurred by the
General Partner and its affiliates have fluctuated during the three years
presented, the amount charged to the Partnerships have not fluctuated every year
due to expense limitations imposed by the Partnership Agreements.

Affiliates of the Partnerships serve as operator of some of the
Partnerships' wells. The General Partner contracts with such affiliates for
services as operator of the wells. As operator, such affiliates are compensated
at rates provided in the operating agreements in effect and charged to all
parties to such agreement. Such compensation may occur both prior and subsequent
to the commencement of commercial marketing of production of oil or gas. The
dollar amount of such compensation paid by the Partnerships to the affiliates is
impossible to quantify as of the date of this Annual Report.

Samson maintains necessary inventories of new and used field equipment.
Samson may have provided some of this equipment for wells in which the
Partnerships have an interest. This equipment was provided at prices or rates
equal to or less than those normally charged in the same or comparable
geographic area by unaffiliated persons or companies dealing at arm's length.
The operators of these wells billed the Partnerships for a portion of such costs
based upon the Partnerships' interest in the well.

ITEM 12. SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table provides information as to the beneficial ownership of
the Units as of the date of filing this Annual Report by (i) each beneficial
owner of more than five percent of the issued and outstanding Units, (ii) the
directors and officers of the General Partner, and (iii) the General Partner and
its affiliates. The address of each of such persons is Samson Plaza, Two West
Second Street, Tulsa, Oklahoma 74103.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

The General Partner and certain of its affiliates engage in oil and gas
activities independently of the Partnerships which result in conflicts of
interest that cannot be totally eliminated. The allocation of acquisition and
drilling opportunities and the nature of the compensation arrangements between
the Partnerships and the General Partner also create potential conflicts of
interest. An affiliate of the Partnerships owns some of the Partnerships' Units
and therefore has an identity of interest with other Limited Partners with
respect to the operations of the Partnerships.

In order to attempt to assure limited liability for Limited Partners as
well as an orderly conduct of business, management of the Partnerships is
exercised solely by the General Partner. The Partnership Agreements grant the
General Partner broad discretionary authority with respect to the Partnerships'
participation in drilling prospects and expenditure and control of funds,
including borrowings. These provisions are similar to those contained in
prospectuses and partnership agreements for other public oil and gas
partnerships. Broad discretion as to general management of the Partnerships
involves circumstances where the General Partner has conflicts of interest and
where it must allocate costs and expenses, or opportunities, among the
Partnerships and other competing interests.

The General Partner does not devote all of its time, efforts, and
personnel exclusively to the Partnerships. Furthermore, the Partnerships do not
have any employees, but instead rely on the personnel of Samson. The
Partnerships thus compete with Samson (including other oil and gas partnerships)
for the time and resources of such personnel. Samson devotes such



-49-




time and personnel to the management of the Partnerships as are indicated by the
circumstances and as are consistent with the General Partner's fiduciary duties.

Affiliates of the Partnerships are solely responsible for the negotiation,
administration, and enforcement of oil and gas sales agreements covering the
Partnerships' leasehold interests. Because affiliates of the Partnerships who
provide services to the Partnerships have fiduciary or other duties to other
members of Samson, contract amendments and negotiating positions taken by them
in their effort to enforce contracts with purchasers may not necessarily
represent the positions that the Partnerships would take if they were to
administer their own contracts without involvement with other members of Samson.
On the other hand, management believes that the Partnerships' negotiating
strength and contractual positions have been enhanced by virtue of their
affiliation with Samson.

ITEM 14. PRINCIPAL ACCOUNTANT FEES AND SERVICES

Audit Fees

During 2004 and 2003, each Partnership paid the following audit fees:

Audit-Related Fees

During 2004 and 2003 the Partnerships did not pay any audit-related fees
of the type required by the SEC to be disclosed in this Annual Report under this
heading.


Tax Fees

During 2004 and 2003 the Partnerships did not pay any tax compliance, tax
advice, or tax planning fees of the type required by the SEC to be disclosed in
this Annual Report under this heading.


All Other Fees

During 2004 and 2003 the Partnerships did not pay any other fees of the

heading.




-50-




Audit Approval

The Partnerships do not have audit committee pre-approval policies and
procedures as described in paragraph (c)(7)(i) of Rule 2-01 of Regulation S-X.
The Partnerships did not receive any services of the type described in Items
9(e)(2) through 9(e)(4) of Schedule 14A.


Audit and Related Fees Paid by Affiliates

The Partnerships' accountants received compensation from other related
partnerships managed by the General Partner and from other entities affiliated
with the General Partner. This compensation is for audit services, tax related
services, and other accounting-related services. The General Partner does not
believe this arrangement creates a conflict of interest or impairs the auditors'
independence.

TO THE PARTNERS

GEODYNE ENERGY INCOME LIMITED PARTNERSHIP I-D
GEODYNE PRODUCTION PARTNERSHIP I-D

In our opinion, the accompanying combined balance sheets and the related
combined statements of operations, changes in partners' capital (deficit) and
cash flows present fairly, in all material respects, the combined financial
position of the Geodyne Energy Income Limited Partnership I-D, an Oklahoma
limited partnership, and Geodyne Production Partnership I-D, an Oklahoma general
partnership, at December 31, 2004 and 2003, and the combined results of their
operations and their cash flows for each of the three years in the period ended
December 31, 2004, in conformity with accounting principles generally accepted
in the United States of America. These financial statements are the
responsibility of the Partnerships' management. Our responsibility is to express
an opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with the standards of the
Public Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for the opinion expressed above.

As discussed in Note 1 of Notes to the Combined Financial Statements under
the heading "Asset Retirement Obligation," effective January 1, 2003 the
Partnerships changed the manner in which they account for asset retirement
obligations.

GEODYNE ENERGY INCOME PROGRAM I LIMITED PARTNERSHIPS
Notes to the Combined Financial Statements
For the Years Ended December 31, 2004, 2003, and 2002


1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Organization and Nature of Operations

The Geodyne Energy Income Limited Partnerships (the "Partnerships") were
formed pursuant to a public offering of depositary units ("Units"). Upon
formation, investors became limited partners (the "Limited Partners") and held
Units issued by each Partnership. Geodyne Resources, Inc. is the general partner
of the Partnerships. Each Partnership is a general partner in the related
Geodyne Energy Income Production Partnership (collectively, the "Production
Partnership") in which Geodyne Resources, Inc. serves as the managing partner.
Limited Partner capital contributions were contributed to the related Production
Partnerships for investment in producing oil and gas properties. The
Partnerships were activated on the following dates with the following Limited
Partner capital contributions:

Limited
Partner
Date of Capital
Partnership Activation Contributions
----------- ------------------ --------------

I-D March 4, 1986 $ 7,194,700
I-E September 10, 1986 41,839,400
I-F December 16, 1986 14,320,900

The Partnerships' original termination date under their partnership
agreements was December 31, 1999. The General Partner has extended the terms of
the Partnerships for their third two-year period to December 31, 2005 pursuant
to its right to extend the term of each Partnership for up to five periods of
two years each.

For purposes of these financial statements, the Partnerships and
Production Partnerships are collectively referred to as the "Partnerships" and
the general partner and managing partner are collectively referred to as the
"General Partner."

An affiliate of the General Partner owned the following Units at December
31, 2004:



F-19





Number of Percent of
Partnership Units Owned Outstanding Units
----------- ----------- -----------------
I-D 2,066 28.7%
I-E 11,756 28.1%
I-F 4,709 32.9%

The Partnerships' sole business is the development and production of oil
and gas. Substantially all of the Partnerships' gas reserves are being sold
regionally on the "spot market." Due to the highly competitive nature of the
spot market, prices on the spot market are subject to wide seasonal and regional
pricing fluctuations. In addition, such spot market sales are generally
short-term in nature and are dependent upon obtaining transportation services
provided by pipelines. The Partnerships' oil is sold at or near the
Partnerships' wells under short-term purchase contracts at prevailing
arrangements which are customary in the oil industry. The prices received for
the Partnerships' oil and gas are subject to influences such as global
consumption and supply trends.


Allocation of Costs and Revenues

The Partnerships have achieved payout and therefore the combination of the
allocation provisions in each Partnership's limited partnership agreement and
each Production Partnership's partnership agreement (collectively, the
"Partnership Agreement") results in allocations of costs and income between the
Limited Partners and General Partner as follows:




F-20




General Limited
Partner Partners
Costs(1) -------- --------
------------------------
Property acquisition
costs 1% 99%
Identified development
drilling 1% 99%
Development drilling 15% 85%
General and administra-
tive costs, direct
administrative costs
and operating costs 15% 85%

Income(1)
------------------------
Temporary investments of
Limited Partners'
capital contributions 1% 99%
Income from oil and gas
production 15% 85%
Sale of producing pro-
perties 15% 85%
All other income 15% 85%

- ----------
(1) The allocations in the table result generally from the combined effect of
the allocation provisions in the Partnership Agreements. For example, the
costs incurred in development drilling are allocated 85.8586% to the
limited partnership and 14.1414% to the managing partner. The 85.8586%
portion of these costs allocated to the limited partnership, when passed
through the limited partnership, is further allocated 99% to the limited
partners and 1% to the general partner. In this manner the Limited
Partners are allocated 85% of such costs and the General Partner is
allocated 15% of such costs.


Basis of Presentation

These financial statements reflect the combined accounts of each
Partnership after the elimination of all inter-partnership transactions and
balances.


Cash and Cash Equivalents

The Partnerships consider all highly liquid investments with a maturity of
three months or less when purchased to be cash equivalents. Cash equivalents are
not insured, which cause the Partnerships to be subject to risk.



F-21




Credit Risk

Accrued oil and gas sales which are due from a variety of oil and gas
purchasers subject the Partnerships to a concentration of credit risk. Some of
these purchasers are discussed in Note 3 - Major Customers.


Oil and Gas Properties

The Partnerships follow the successful efforts method of accounting for
their oil and gas properties. Under the successful efforts method, the
Partnerships capitalize all property acquisition costs and development costs
incurred in connection with the further development of oil and gas reserves.
Property acquisition costs include costs incurred by the Partnerships or the
General Partner to acquire producing properties, including related title
insurance or examination costs, commissions, engineering, legal and accounting
fees, and similar costs directly related to the acquisitions, plus an allocated
portion of the General Partner's property screening costs. The acquisition cost
to the Partnerships of properties acquired by the General Partner is adjusted to
reflect the net cash results of operations, including interest incurred to
finance the acquisition, for the period of time the properties are held by the
General Partner.

Depletion of the cost of producing oil and gas properties, amortization of
related intangible drilling and development costs, and depreciation of tangible
lease and well equipment are computed on the units-of-production method. The
Partnerships' depletion, depreciation, and amortization includes dismantlement
and abandonment costs, net of estimated salvage value. The depreciation,
depletion, and amortization rates, which include accretion of the asset
retirement obligation, per equivalent barrel of oil produced during the years
ended December 31, 2004, 2003, and 2002, were as follows:

Partnership 2004 2003 2002
----------- ----- ----- -----

I-D $1.19 $2.15 $ .84
I-E 1.08 2.24 .97
I-F 1.18 1.22 .94

When complete units of depreciable property are retired or sold, the asset
cost, related accumulated depreciation, and remaining asset retirement
obligation, are eliminated with any gain or loss reflected in income. When less
than complete units of depreciable property are retired or sold, the proceeds
are credited to oil and gas properties.

The Partnerships evaluate the recoverability of the carrying costs of
their proved oil and gas properties at the field level.



F-22




If the unamortized costs of oil and gas properties within a field exceed the
expected undiscounted future cash flows from such properties, the cost of the
properties is written down to fair value, which is determined by using the
discounted future cash flows from the properties. No impairment provisions were
recorded by the Partnerships during the three years ended December 31, 2004. The
risk that the Partnerships will be required to record impairment provisions in
the future increases as oil and gas prices decrease.


Deferred Charge

The Deferred Charge represents costs deferred for lease operating expenses
incurred in connection with the Partnerships' underproduced gas imbalance
positions. The rate used in calculating the deferred charge is the average
annual production costs per Mcf. At December 31, 2004 and 2003, cumulative total
gas sales volumes for underproduced wells were less than the Partnerships'
pro-rata share of total gas production from these wells by the following
amounts:

2004 2003
------------------ -------------------
Partnership Mcf Amount Mcf Amount
----------- ------- -------- ------- --------

I-D 157,314 $ 82,606 164,858 $ 86,567
I-E 636,910 424,309 683,121 455,095
I-F 266,208 326,610 283,512 347,840


Accrued Liability - Other

The Accrued Liability - Other at December 31, 2004 and 2003 for the I-E
and I-F Partnerships represents a charge accrued for the payment of a judgment
related to plugging liabilities, which judgment is currently under appeal. A
decision is expected in 2005.


Accrued Liability

The Accrued Liability represents charges accrued for lease operating
expenses incurred in connection with the Partnerships' overproduced gas
imbalance positions. The rate used in calculating the accrued liability is the
average annual production costs per Mcf. At December 31, 2004 and 2003,
cumulative total gas sales volumes for overproduced wells exceeded the
Partnerships' pro-rata share of total gas production from these wells by the
following amounts:




F-23




2004 2003
---------------------- --------------------
Partnership Mcf Amount Mcf Amount
----------- ------- -------- ------- --------

I-D 57,956 $ 30,433 67,430 $ 35,408
I-E 236,623 157,638 279,554 186,239
I-F 113,386 139,114 123,393 151,391


Oil and Gas Sales and Gas Imbalance Payable

The Partnerships' oil and condensate production is sold, title passed, and
revenue recognized at or near the Partnerships' wells under short-term purchase
contracts at prevailing prices in accordance with arrangements which are
customary in the oil industry. Sales of gas applicable to the Partnerships'
interest in producing oil and gas leases are recorded as revenue when the gas is
metered and title transferred pursuant to the gas sales contracts covering the
Partnerships' interest in gas reserves. During such times as a Partnership's
sales of gas exceed its pro rata ownership in a well, such sales are recorded as
revenue unless total sales from the well have exceeded the Partnership's share
of estimated total gas reserves underlying the property, at which time such
excess is recorded as a liability. The rates per Mcf used to calculate this
liability are based on the average gas prices for which the Partnerships are
currently settling this liability. At December 31, 2004 and 2003 total sales
exceeded the Partnerships' share of estimated total gas reserves as follows:


2004 2003
------------------- -----------------
Partnership Mcf Amount Mcf Amount
----------- ------ -------- ------ -------

I-D 23,058 $ 34,587 18,905 $28,358
I-E 78,175 117,263 61,999 92,999
I-F 25,240 37,860 20,593 30,890

These amounts were recorded as gas imbalance payables in accordance with the
sales method. These gas imbalance payables will be settled by either gas
production by the underproduced party in excess of current estimates of total
gas reserves for the well or by a negotiated or contractual payment to the
underproduced party.

The Partnerships have not entered into any hedging or derivative contracts
in connection with their production and sale of oil and gas.




F-24




General and Administrative Overhead

The General Partner and its affiliates are reimbursed for actual general
and administrative costs incurred and attributable to the conduct of the
business affairs and operations of the Partnerships.


Use of Estimates in Financial Statements

The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates. Further, the
deferred charge, the gas imbalance payable, the asset retirement obligations,
and the accrued liability all involve estimates which could materially differ
from the actual amounts ultimately realized or incurred in the near term. Oil
and gas reserves (see Note 4) also involve significant estimates which could
materially differ from the actual amounts ultimately realized.


Asset Retirement Obligation

In July 2001, the FASB issued FAS No. 143, "Accounting for Asset
Retirement Obligations", which is effective for fiscal years beginning after
June 15, 2002 (January 1, 2003 for the Partnerships). FAS No. 143 requires the
fair value of a liability for an asset retirement obligation to be recognized in
the period in which it is incurred if a reasonable estimate of fair value can be
made, and that the associated asset retirement costs be capitalized as part of
the carrying amount of the long-lived asset. The Partnerships own interests in
oil and gas properties which require expenditures to plug and abandon the wells
when reserves in the wells are depleted. On January 1, 2003, the Partnerships
adopted FAS No. 143 and recorded an increase in capitalized cost of oil and gas
properties, an increase (decrease) in net income for the cumulative effect of
the change in accounting principle, and an asset retirement obligation in the
following approximate amounts for each Partnership:





F-25




Increase
Increase in Decrease) in
Capitalized Net Income for
Cost of Oil the Change in Asset
and Gas Accounting Retirement
Partnership Properties Principle Obligation
- ----------- ------------ -------------- ----------
I-D $ 30,000 $1,000 $ 29,000
I-E 278,000 4,000 274,000
I-F 119,000 ( 300) 119,000


The asset retirement obligation is adjusted upwards each quarter in order
to recognize accretion of the time-related discount factor. For the year ended
December 31, 2004, the I-D, I-E, and I-F Partnerships recognized approximately
$2,000, $25,000, and $15,000, respectively, of an increase in depreciation,
depletion, and amortization expense, which was comprised of accretion of the
asset retirement obligation and depletion of the increase in capitalized cost of
oil and gas properties.

The components of the change in asset retirement obligations for the years
ended December 31, 2004 and December 31, 2003 are as shown below.

Had FAS No. 143 been adopted at January 1, 2002 the amount of the asset
retirement obligation at that date and at December 31, 2002 would not have been
materially different from the amount recorded at January 1, 2003. If this
accounting policy had been in effect on January 1, 2002, the pro forma impact
for the I-D, I-E, and I-F Partnerships during the year ended December 31, 2002
would have been an increase in depreciation, depletion, and amortization expense
of approximately $1,000, $10,000, and $5,000, respectively.



F-27





Income Taxes

Income or loss for income tax purposes is includable in the income tax
returns of the partners. Accordingly, no recognition has been given to income
taxes in these financial statements.




2. TRANSACTIONS WITH RELATED PARTIES

The Partnerships reimburse the General Partner for the general and
administrative overhead applicable to the Partnerships, based on an allocation
of actual costs incurred by the General Partner. When actual costs incurred
benefit other Partnerships and affiliates, the allocation of costs is based on
the relationship of the Partnerships' reserves to the total reserves owned by
all Partnerships and affiliates. The General Partner believes this allocation
method is reasonable. Although the actual costs incurred by the General Partner
and its affiliates have fluctuated during the three years presented, the amounts
charged to the Partnerships have not fluctuated every year due to expense
limitations imposed by the Partnership Agreements. The following is a summary of
payments made to the General Partner or its affiliates by the Partnerships for
general and administrative overhead costs for the years ended December 31, 2004,
2003, and 2002:

Partnership 2004 2003 2002
----------- -------- -------- --------

I-D $ 79,944 $ 79,944 $ 79,944
I-E 464,880 464,880 464,880
I-F 159,120 159,120 159,120

Affiliates of the Partnerships operate certain of the Partnerships'
properties and their policy is to bill the Partnerships for all customary
charges and cost reimbursements associated with these activities, together with
any compressor rentals, consulting, or other services provided.


3. MAJOR CUSTOMERS

The following table sets forth purchasers who individually accounted for
ten percent or more of each Partnership's combined oil and gas sales for the
years ended December 31, 2004, 2003, and 2002:

In the event of interruption of purchases by one or more of these
significant customers or the cessation or material change in availability of
open-access transportation by the Partnerships' pipeline transporters, the
Partnerships may encounter difficulty in marketing their gas and in maintaining
historic sales levels. Alternative purchasers or transporters may not be readily
available.
