Part I

Item 1. Business

General
Southwest Royalties Institutional Income Fund VII-B, L.P. (the
"Partnership" or "Registrant") was organized as a Delaware limited
partnership on January 28, 1987. The offering of limited partnership
interests began March 23, 1987, reached minimum capital requirements May
20, 1987, and concluded December 1, 1987. The Partnership has no
subsidiaries.

The Partnership has expended its capital and acquired interests in
producing oil and gas properties. After such acquisitions, the Partnership
has produced and marketed the crude oil and natural gas produced from such
properties. In most cases, the Partnership purchased royalty or overriding
royalty interests and working interests in oil and gas properties that were
converted into net profits interests or other nonoperating interests. The
Partnership purchased either all or part of the rights and obligations
under various oil and gas leases.

The principal executive offices of the Partnership are located at 407 N.
Big Spring, Suite 300, Midland, Texas, 79701. The Managing General Partner
of the Partnership, Southwest Royalties, Inc. (the "Managing General
Partner") and its staff of 89 individuals, together with certain
independent consultants used on an "as needed" basis, perform various
services on behalf of the Partnership, including the selection of oil and
gas properties and the marketing of production from such properties. H. H.
Wommack, III, a stockholder, director, President and Treasurer of the
Managing General Partner, is also a general partner. Effective December
31, 2001, Mr. Wommack sold his general partner interest to the Managing
General Partner. The Partnership has no employees.

Principal Products, Marketing and Distribution
The Partnership has acquired and holds royalty, overriding royalty and net
profit interests in oil and gas properties located in Texas, New Mexico,
Oklahoma and Louisiana. All activities of the Partnership are confined to
the continental United States. All oil and gas produced from these
properties is sold to unrelated third parties in the oil and gas business.

The revenues generated from the Partnership's oil and gas activities are
dependent upon the current market for oil and gas. The prices received by
the Partnership for its oil and gas production depend upon numerous factors
beyond the Partnership's control, including competition, economic,
political and regulatory developments and competitive energy sources, and
make it particularly difficult to estimate future prices of oil and natural
gas.



For nearly nine months, despite the fears of a global recession, crude oil
prices held steady between $26 and $28 per barrel due in part to a series
of OPEC and non-OPEC production cuts. Then, following what has become
known simply as "9-11", crude prices plunged immediately to $22 and
gradually fell to below $18 per barrel. Slower demand across the U.S.
caused by the threat of recession and warmer than expected weather also led
to declining prices in the latter half of 2001. However, the oil cartel
and other non-member countries agreed for the fourth time since February to
curb output in an effort to stabilize prices. Crude oil contracts trading
on the NYMEX closed the year at approximately $20 per barrel.

Spot prices in 2001 climbed to their highest levels ever, with the yearly
average price nationwide reaching $4.14/MMBtu, up 9.77% from the 2000
average of $3.77/MMBtu. Prices reached their zenith in the first quarter
of 2001 before beginning a steady decline throughout the remainder of the
year. The terrorist attacks of September 11 knocked the New York
Mercantile Exchange out of the market for several days and shook the spot
marketplace into a maintenance mode. As companies measured the impact of
the attacks on the U.S. economy, spot prices deteriorated further. In the
fourth quarter, prices bottomed out for the year with the three-month
average falling to $2.31/MMBtu. As for 2002, record-high storage levels
and the expectation of a flat economy through the first half of the year
are leading industry experts to predict prices to average $2.05/MMBtu,
remaining above the $2.00 per MMBtu level for a 5th consecutive year.

Following is a table of the ratios of revenues received from oil and gas
production for the last three years:

Oil Gas

2001 72% 28%
2000 73% 27%
1999 74% 26%


As the table indicates, the majority of the Partnership's revenue is from
its oil production and Partnership revenues will be highly dependent upon
the future prices and demands for oil.

Seasonality of Business
Although the demand for natural gas is highly seasonal, with higher demand
in the colder winter months and in very hot summer months, the Partnership
has been able to sell all of its natural gas, either through contracts in
place or on the spot market at the then prevailing spot market price. As a
result, the volumes sold by the Partnership have not fluctuated materially
with the change of season.

Customer Dependence
No material portion of the Partnership's business is dependent on a single
purchaser, or a very few purchasers, where the loss of one would have a
material adverse impact on the Partnership. Four purchasers accounted for
66% of the Partnership's total oil and gas production during 2001: Equiva
Trading Company for 23%, Duke Energy Field Services for 21%, BP Amoco for
11% and Plains Marketing LP for 11%. Four purchasers accounted for 77% of
the Partnership's total oil and gas production during 2000: Phillips 66
Natural Gas Co. for 28%, Equiva Trading Company for 19%, BP Amoco for 17%
and Plains Marketing LP for 13%. Four purchasers accounted for 74% of the
Partnership's total oil and gas production during 1999: Phillips 66 Natural
Gas Co. for 27%, Equiva Trading Company for 19%, Amoco Production for 17%
and Scurlock Permian LLC. for 11%. All purchasers of the Partnership's oil
and gas production are unrelated third parties. In the event any of these
purchasers were to discontinue purchasing the Partnership's production, the
Managing General Partner believes that a substitute purchaser or purchasers
could be located without undue delay. No other purchaser accounted for an
amount equal to or greater than 10% of the Partnership's sales of oil and
gas production.



Competition
Because the Partnership has utilized all of its funds available for the
acquisition of net profits or royalty interests in producing oil and gas
properties, it is not subject to competition from other oil and gas
property purchasers. See Item 2, Properties.

Factors that may adversely affect the Partnership include delays in
completing arrangements for the sale of production, availability of a
market for production, rising operating costs of producing oil and gas and
complying with applicable water and air pollution control statutes,
increasing costs and difficulties of transportation, and marketing of
competitive fuels. Moreover, domestic oil and gas must compete with
imported oil and gas and with coal, atomic energy, hydroelectric power and
other forms of energy.

Regulation

Oil and Gas Production - The production and sale of oil and gas is subject
to federal and state governmental regulation in several respects, such as
existing price controls on natural gas and possible price controls on crude
oil, regulation of oil and gas production by state and local governmental
agencies, pollution and environmental controls and various other direct and
indirect regulations. Many jurisdictions have periodically imposed
limitations on oil and gas production by restricting the rate of flow for
oil and gas wells below their actual capacity to produce and by imposing
acreage limitations for the drilling of wells. The federal government has
the power to permit increases in the amount of oil imported from other
countries and to impose pollution control measures.

Various aspects of the Partnership's oil and gas activities are regulated
by administrative agencies under statutory provisions of the states where
such activities are conducted and by certain agencies of the federal
government for operations on Federal leases. Moreover, certain prices at
which the Partnership may sell its natural gas production are controlled by
the Natural Gas Policy Act of 1978, the Natural Gas Wellhead Decontrol Act
of 1989 and the regulations promulgated by the Federal Energy Regulatory
Commission.

Environmental - The Partnership's oil and gas activities are subject to
extensive federal, state and local laws and regulations governing the
generation, storage, handling, emission, transportation and discharge of
materials into the environment. Governmental authorities have the power to
enforce compliance with their regulations, and violations carry substantial
penalties. This regulatory burden on the oil and gas industry increases
its cost of doing business and consequently affects its profitability. The
Managing General Partner is unable to predict what, if any, effect
compliance will have on the Partnership.

Industry Regulations and Guidelines - Certain industry regulations and
guidelines apply to the registration, qualification and operation of oil
and gas programs in the form of limited partnerships. The Partnership is
subject to these guidelines which regulate and restrict transactions
between the Managing General Partner and the Partnership.

The Partnership complies with these guidelines and the Managing General
Partner does not anticipate that continued compliance will have a material
adverse effect on Partnership operations.

Partnership Employees
The Partnership has no employees; however the Managing General Partner has
a staff of geologists, engineers, accountants, landmen and clerical staff
who engage in Partnership activities and operations and perform additional
services for the Partnership as needed. In addition to the Managing
General Partner's staff, the Partnership engages independent consultants
such as petroleum engineers and geologists as needed. As of December 31,
2001, there were 89 individuals directly employed by the Managing General
Partner in various capacities.


Item 2. Properties

In determining whether an interest in a particular producing property was
to be acquired, the Managing General Partner considered such criteria as
estimated oil and gas reserves, estimated cash flow from the sale of
production, present and future prices of oil and gas, the extent of
undeveloped and unproved reserves, the potential for secondary, tertiary
and other enhanced recovery projects and the availability of markets.

As of December 31, 2001, the Partnership possessed an interest in oil and
gas properties located in Cameron Parish of Louisiana; Eddy and Lea
Counties of New Mexico; Caddo, Garvin, Leflore, McClain and Pottawatomie
Counties of Oklahoma; Andrews, Dawson, Ector, Fisher, Gaines, Garza, Hale,
Hockley, Howard, Lamb, Leon, Loving, Martin, Midland, Pecos, Rusk, Scurry,
Stonewall, Tom Green, Upton, Ward and Winkler Counties of Texas. These
properties consist of various interests in approximately 2,650 wells and
units.

Due to the Partnership's objective of maintaining current operations
without engaging in the drilling of any developmental or exploratory wells,
or additional acquisitions of producing properties, there has not been any
significant changes in properties during 2001, 2000 and 1999.

Significant Properties
The following table reflects the significant properties in which the
Partnership has an interest:

*Ryder Scott Petroleum Engineers prepared the reserve and present value
data for the Partnership's existing properties as of January 1, 2002. The
reserve estimates were made in accordance with guidelines established by
the Securities and Exchange Commission pursuant to Rule 4-10(a) of
Regulation S-X. Such guidelines require oil and gas reserve reports be
prepared under existing economic and operating conditions with no
provisions for price and cost escalation except by contractual
arrangements.

Oil price adjustments were made in the individual evaluations to reflect
oil quality, gathering and transportation costs. The results of the reserve
report as of January 1, 2002 are an average price of $17.99 per barrel.

Gas price adjustments were made in the individual evaluations to reflect
BTU content, gathering and transportation costs and gas processing and
shrinkage. The results of the reserve report as of January 1, 2002 are an
average price of $2.21 per Mcf.

As also discussed in Part II, Item 7, Management's Discussion and Analysis
of Financial Condition and Results of Operations, oil and gas prices were
subject to frequent changes in 2001.



The evaluation of oil and gas properties is not an exact science and
inevitably involves a significant degree of uncertainty, particularly with
respect to the quantity of oil or gas that any given property is capable of
producing. Estimates of oil and gas reserves are based on available
geological and engineering data, the extent and quality of which may vary
in each case and, in certain instances, may prove to be inaccurate.
Consequently, properties may be depleted more rapidly than the geological
and engineering data have indicated.

Unanticipated depletion, if it occurs, will result in lower reserves than
previously estimated; thus an ultimately lower return for the Partnership.
Basic changes in past reserve estimates occur annually. As new data is
gathered during the subsequent year, the engineer must revise his earlier
estimates. A year of new information, which is pertinent to the estimation
of future recoverable volumes, is available during the subsequent year
evaluation. In applying industry standards and procedures, the new data
may cause the previous estimates to be revised. This revision may increase
or decrease the earlier estimated volumes. Pertinent information gathered
during the year may include actual production and decline rates, production
from offset wells drilled to the same geologic formation, increased or
decreased water production, workovers, and changes in lifting costs, among
others. Accordingly, reserve estimates are often different from the
quantities of oil and gas that are ultimately recovered.

The Partnership has reserves which are classified as proved developed
producing, proved developed non-producing and proved undeveloped. All of
the proved reserves are included in the engineering reports which evaluate
the Partnership's present reserves.

Because the Partnership does not engage in drilling activities, the
development of proved undeveloped reserves is conducted pursuant to
farmout, arrangements with the Managing General Partner or unrelated third
parties. Generally, the Partnership retains a carried interest such as an
overriding royalty interest under the terms of a farmout, or receives cash.

The Partnership or the owners of properties in which the Partnership owns
an interest can engage in workover projects or supplementary recovery
projects, for example, to extract behind the pipe reserves which qualify as
proved developed non-producing reserves. See Part II, Item 7, Management's
Discussion and Analysis of Financial Condition and Results of Operations.

Item 3. Legal Proceedings

There are no material pending legal proceedings to which the Partnership is
a party.

Item 4. Submission of Matters to a Vote of Security Holders

No matter was submitted to a vote of security holders during the fourth
quarter of 2001 through the solicitation of proxies or otherwise.

Item 5. Market for the Registrant's Common Equity and Related
Stockholder Matters

Market Information
Limited partnership interests, or units, in the Partnership were initially
offered and sold for a price of $500. Limited partner units are not traded
on any exchange and there is no public or organized trading market for
them. The Managing General Partner has become aware of certain limited and
sporadic transfers of units between limited partners and third parties, but
has no verifiable information regarding the prices at which such units have
been transferred. Further, a transferee may not become a substitute
limited partner without the consent of the Managing General Partner.

After completion of the Partnership's first full fiscal year of operations
and each year thereafter, the Managing General Partner has offered and will
continue to offer to purchase each limited partner's interest in the
Partnership, at a price based on tangible assets of the Partnership, plus
the present value of the future net revenues of proved oil and gas
properties, minus liabilities with a risk factor discount of up to one-
third which may be implemented in the sole discretion of the Managing
General Partner. However, the Managing General Partner's obligation to
purchase limited partner units is limited to an expenditure of an amount
not in excess of 10% of the total limited partner units initially
subscribed for by limited partners. In 2001, 1,361 limited partner units
were tendered to and purchased by the Managing General Partner at an
average base price of $223.82 per unit. In 2000, 1,063 limited partner
units were tendered to and purchased by the Managing General Partner at an
average base price of $121.97 per unit. In 1999, 203 limited partner units
were tendered to and purchased by the Managing General Partner at an
average base price of $63.70 per unit.

Number of Limited Partner Interest Holders
As of December 31, 2001, there were 718 holders of limited partner units in
the Partnership.

Distributions
Pursuant to Article IV, Section 4.01 of the Partnership's Certificate and
Agreement of Limited Partnership "Net Cash Flow" is distributed to the
partners on a quarterly basis. "Net Cash Flow" is defined as "the cash
generated by the Partnership's investments in producing oil and gas
properties, less (i) General and Administrative Costs, (ii) Operating
Costs, and (iii) any reserves necessary to meet current and anticipated
needs of the Partnership, as determined in the sole discretion of the
Managing General Partner."



During 2001, quarterly distributions were made totaling $726,729, with
$654,056 distributed to the limited partners and $72,673 to the general
partners. For the year ended December 31, 2001, distributions of $43.60
per limited partner unit were made, based upon 15,000 limited partner units
outstanding. During 2000, quarterly distributions were made totaling
$587,183, with $528,465 distributed to the limited partners and $58,718 to
the general partners. For the year ended December 31, 2000, distributions
of $35.23 per limited partner unit were made, based upon 15,000 limited
partner units outstanding. During 1999, distributions were made totaling
$344,786, with $311,786 distributed to the limited partners and $33,000 to
the general partners. For the year ended December 31, 1999, distributions
of $20.79 per limited partner unit were made, based upon 15,000 limited
partner units outstanding.

Item 7. Management's Discussion and Analysis of Financial Condition and
Results of Operations

General
The Partnership was formed to acquire nonoperating interests in producing
oil and gas properties, to produce and market crude oil and natural gas
produced from such properties and to distribute any net proceeds from
operations to the general and limited partners. Net revenues from
producing oil and gas properties are not reinvested in other revenue
producing assets except to the extent that producing facilities and wells
are reworked or where methods are employed to improve or enable more
efficient recovery of oil and gas reserves. The economic life of the
Partnership thus depends on the period over which the Partnership's oil and
gas reserves are economically recoverable.

Increases or decreases in Partnership revenues and, therefore,
distributions to partners will depend primarily on changes in the prices
received for production, changes in volumes of production sold, lease
operating expenses, enhanced recovery projects, offset drilling activities
pursuant to farmout arrangements and on the depletion of wells. Since
wells deplete over time, production can generally be expected to decline
from year to year.

Well operating costs and general and administrative costs usually decrease
with production declines; however, these costs may not decrease
proportionately. Net income available for distribution to the limited
partners has fluctuated over the past few years and is expected to
fluctuate in later years based on these factors.

Based on current conditions, management anticipates performing workovers
during 2002 to enhance production. The partnership may have an increase in
production volumes for the year 2002, otherwise, the partnership will most
likely experience the historical production decline of approximately 8% per
year.

Critical Accounting Policies
Full cost ceiling calculations The Partnership follows the full cost method
of accounting for its oil and gas properties. The full cost method
subjects companies to quarterly calculations of a "ceiling", or limitation
on the amount of properties that can be capitalized on the balance sheet.
If the Partnership's capitalized costs are in excess of the calculated
ceiling, the excess must be written off as an expense.

The Partnership's discounted present value of its proved oil and natural
gas reserves is a major component of the ceiling calculation, and
represents the component that requires the most subjective judgments.
Estimates of reserves are forecasts based on engineering data, projected
future rates of production and the timing of future expenditures. The
process of estimating oil and natural gas reserves requires substantial
judgment, resulting in imprecise determinations, particularly for new
discoveries. Different reserve engineers may make different estimates of
reserve quantities based on the same data. The Partnership's reserve
estimates are prepared by outside consultants.

The passage of time provides more qualitative information regarding
estimates of reserves, and revisions are made to prior estimates to reflect
updated information. However, there can be no assurance that more
significant revisions will not be necessary in the future. If future
significant revisions are necessary that reduce previously estimated
reserve quantities, it could result in a full cost property writedown. In
addition to the impact of these estimates of proved reserves on calculation
of the ceiling, estimates of proved reserves are also a significant
component of the calculation of DD&A.

While the quantities of proved reserves require substantial judgment, the
associated prices of oil and natural gas reserves that are included in the
discounted present value of the reserves do not require judgment. The
ceiling calculation dictates that prices and costs in effect as of the last
day of the period are generally held constant indefinitely. Because the
ceiling calculation dictates that prices in effect as of the last day of
the applicable quarter are held constant indefinitely, the resulting value
is not indicative of the true fair value of the reserves. Oil and natural
gas prices have historically been cyclical and, on any particular day at
the end of a quarter, can be either substantially higher or lower than the
Partnership's long-term price forecast that is a barometer for true fair
value.



The Partnership's policy for depreciation, depletion and amortization of
oil and gas properties is computed under the units of revenue method.
Under the units of revenue method, depreciation, depletion and amortization
is computed on the basis of current gross revenues from production in
relation to future gross revenues, based on current prices, from estimated
production of proved oil and gas reserves.

Results of Operations

A. General Comparison of the Years Ended December 31, 2001 and 2000

The following table provides certain information regarding performance
factors for the years ended December 31, 2001 and 2000:

Year Ended Percentage
December 31, Increase
2001 2000 (Decrease)
---- ---- ---------
Average price per barrel of oil $ 23.72 28.69 (17%)
Average price per mcf of gas $ 3.89 4.09 (5%)
Oil production in barrels 28,400 28,700 (1%)
Gas production in mcf 65,800 73,600 (11%)
Income from net profits interests $ 679,787 867,334 (22%)
Partnership distributions $ 726,729 587,183 24%
Limited partner distributions $ 654,056 528,465 24%
Per unit distribution to limited partners $ 43.60 35.23 24%
Number of limited partner units 15,000 15,000

Revenues

The Partnership's income from net profits interests decreased to $679,787
from $867,334 for the years ended December 31, 2001 and 2000, respectively,
a decrease of 22%. The principal factors affecting the comparison of the
years ended December 31, 2001 and 2000 are as follows:

1. The average price for a barrel of oil received by the Partnership
decreased during the year ended December 31, 2001 as compared to the
year ended December 31, 2000 by 17%, or $4.97 per barrel, resulting in
a decrease of approximately $141,100 in income from net profits
interests. Oil sales represented 72% of total oil and gas sales during
the year ended December 31, 2001 as compared to 73% during the year
ended December 31, 2000.

The average price for an mcf of gas received by the Partnership
decreased during the same period by 5%, or $.20 per mcf, resulting in a
decrease of approximately $13,200 in income from net profits interests.

The total decrease in income from net profits interests due to the
change in prices received from oil and gas production is approximately
$154,300. The market price for oil and gas has been extremely volatile
over the past decade and management expects a certain amount of
volatility to continue in the foreseeable future.


2. Oil production decreased approximately 300 barrels or 1% during the
year ended December 31, 2001 as compared to the year ended December 31,
2000, resulting in a decrease of approximately $8,600 in income from
net profits interests.

Gas production decreased approximately 7,800 mcf or 11% during the same
period, resulting in a decrease of approximately $31,900 in income from
net profits interests.

The total decrease in income from net profits interests due to the
change in production is approximately $40,500.

3. Lease operating costs and production taxes were 3% lower, or
approximately $7,200 less during the year ended December 31, 2001 as
compared to the year ended December 31, 2000.

Costs and Expenses

Total costs and expenses increased to $212,165 from $179,165 for the years
ended December 31, 2001 and 2000, respectively, an increase of 18%. The
increase is the result of higher depletion expense, partially offset by a
decrease in general and administrative expense.

1. General and administrative costs consists of independent accounting and
engineering fees, computer services, postage, and Managing General
Partner personnel costs. General and administrative costs decreased 2%
or approximately $2,000 during the year ended December 31, 2001 as
compared to the year ended December 31, 2000.

2. Depletion expense increased to $97,000 for the year ended December 31,
2001 from $62,000 for the same period in 2000. This represents an increase
of 56%. Depletion is calculated using the units of revenue method of
amortization based on a percentage of current period gross revenues to
total future gross oil and gas revenues, as estimated by the Partnership's
independent petroleum consultants.

The major factor to the increase in depletion expense between the
comparative periods was the decrease in the price of oil and gas used
to determine the Partnership's reserves for January 1, 2002 as compared
to 2001, and the decrease in oil and gas revenues received by the
Partnership during 2001 as compared to 2000. Revisions of previous
estimates can be attributed to the changes in production performance,
oil and gas price and production costs. The impact of the revision
would have increased depletion expense approximately $7,000 as of

B. General Comparison of the Years Ended December 31, 2000 and 1999

The following table provides certain information regarding performance
factors for the years ended December 31, 2000 and 1999:

Year Ended Percentage
December 31, Increase
2000 1999 (Decrease)
---- ---- ---------
Average price per barrel of oil $ 28.69 17.53 64%
Average price per mcf of gas $ 4.09 2.26 81%
Oil production in barrels 28,700 29,920 (4%)
Gas production in mcf 73,600 81,520 (10%)
Income from net profits interests $ 867,334 509,251 70%
Partnership distributions $ 587,183 344,786 70%
Limited partner distributions $ 528,465 311,786 70%
Per unit distribution to limited partners $ 35.23 19.80 78%
Number of limited partner units 15,000 15,000

Revenues

The Partnership's income from net profits interests increased to $867,334
from $509,251 for the years ended December 31, 2000 and 1999, respectively,
an increase of 70%. The principal factors affecting the comparison of the
years ended December 31, 2000 and 1999 are as follows:

1. The average price for a barrel of oil received by the Partnership
increased during the year ended December 31, 2000 as compared to the
year ended December 31, 1999 by 64%, or $11.16 per barrel, resulting in
an increase of approximately $320,300 in income from net profits
interests. Oil sales represented 73% of total oil and gas sales during
the year ended December 31, 2000 as compared to 74% during the year
ended December 31, 1999.

The average price for an mcf of gas received by the Partnership
increased during the same period by 81%, or $1.83 per mcf, resulting in
an increase of approximately $134,700 in income from net profits
interests.

The total increase in income from net profits interests due to the
change in prices received from oil and gas production is approximately
$455,000. The market price for oil and gas has been extremely volatile
over the past decade and management expects a certain amount of
volatility to continue in the foreseeable future.


2. Oil production decreased approximately 1,220 barrels or 4% during the
year ended December 31, 2000 as compared to the year ended December 31,
1999, resulting in a decrease of approximately $21,400 in income from
net profits interests.

Gas production decreased approximately 7,920 mcf or 10% during the same
period, resulting in a decrease of approximately $17,900 in income from
net profits interests.

The total decrease in income from net profits interests due to the
change in production is approximately $39,300.

3. Lease operating costs and production taxes were 29% higher, or
approximately $57,600 more during the year ended December 31, 2000 as
compared to the year ended December 31, 1999. The increase in lease
operating costs and production taxes is due in part to one lease having
major repairs and maintenance such as downhole well repairs, and in
part to the rise in production taxes directly associated with the rise
in oil and gas prices received during the past year. The rise in oil
and gas prices for 2000 has allowed the Partnership to perform these
repairs and maintenance in the hopes of increasing production, thereby
increasing revenues.

Costs and Expenses

Total costs and expenses decreased to $179,165 from $196,122 for the years
ended December 31, 2000 and 1999, respectively, a decrease of 9%. The
decrease is the result of higher general and administrative expense,
partially offset by a decrease in depletion expense.

1. General and administrative costs consists of independent accounting and
engineering fees, computer services, postage, and Managing General
Partner personnel costs. General and administrative costs increased 4%
or approximately $4,000 during the year ended December 31, 2000 as
compared to the year ended December 31, 1999.

3. Depletion expense decreased to $62,000 for the year ended December 31,
2000 from $83,000 for the same period in 1999. This represents a decrease
of 25%. Depletion is calculated using the units of revenue method of
amortization based on a percentage of current period gross revenues to
total future gross oil and gas revenues, as estimated by the Partnership's
independent petroleum consultants.

The major factor to the decrease in depletion expense between the
comparative periods was the increase in the price of oil and gas used
to determine the Partnership's reserves for January 1, 2001 as compared
to 2000. Revisions of previous estimates can be attributed to the
changes in production performance, oil and gas price and production
costs. The impact of the revision would have increased depletion
expense approximately $9,000 as of December 31, 1999.




C. Revenue and Distribution Comparison

Partnership net income for the years ended December 31, 2001, 2000 and 1999
was $473,239, $696,586 and $316,929, respectively. Excluding the effects
of depreciation, depletion and amortization, net income for the years ended
December 31, 2001, 2000 and 1999 would have been $570,239, $758,586 and
$399,929, respectively. Correspondingly, Partnership distributions for the
years ended December 31, 2001, 2000 and 1999 were $726,729, $587,183 and
$344,786, respectively. These differences are indicative of the changes in
oil and gas prices, production and property during 2001, 2000 and 1999.

The sources of the 2001 distributions of $726,729 were oil and gas
operations of approximately $689,000 and the change in oil and gas
properties of approximately $100, with the balance from available cash on
hand at the beginning of the period. The sources for the 2000
distributions of $587,200 were oil and gas operations of approximately
$680,921, resulting in excess cash for contingencies or subsequent
distributions. The source for the 1999 distributions of $344,786 was oil
and gas operations of approximately $306,020 and the change in oil and gas
properties of approximately $14,900, with the balance from available cash
on hand at the beginning of the period.

Total distributions during the year ended December 31, 2001 were $726,729
of which $654,056 was distributed to the limited partners and $72,673 to
the general partners. The per unit distribution to limited partners during
the same period was $43.60. Total distributions during the year ended
December 31, 2000 were $587,183 of which $528,465 was distributed to the
limited partners and $58,718 to the general partners. The per unit
distribution to limited partners during the same period was $35.23. Total
distributions during the year ended December 31, 1999 were $344,786 of
which $311,786 was distributed to the limited partners and $33,000 to the
general partners. The per unit distribution to limited partners during the
same period was $20.79.

Since inception of the Partnership, cumulative monthly cash distributions
of $10,794,295 have been made to the partners. As of December 31, 2001,
$9,729,776 or $648.65 per limited partner unit, has been distributed to the
limited partners, representing a 130% return of the capital contributed.

Liquidity and Capital Resources

The primary source of cash is from operations, the receipt of income from
net profits interests in oil and gas properties. The Partnership knows of
no material change, nor does it anticipate any such change.

Cash flows provided by operating activities were approximately $689,000 in
2001 compared to $680,900 in 2000 and approximately $306,000 in 1999. The
primary source of the 2001 cash flow from operating activities was
profitable operations.

Cash flows provided by investing activities were approximately $100 in
2001. The Partnership had no cash flows from investing activities in 2000.
Cash flows provided by investing activities were approximately $14,900 in
1999.

Cash flows used in financing activities were approximately $726,900 in 2001
compared $587,000 in 2000 and approximately $345,300 in 1999. The only use
in financing activities was the distributions to partners.

As of December 31, 2001, the Partnership had approximately $188,900 in
working capital. The Managing General Partner knows of no unusual
contractual commitments and believes the revenues generated from operations
are adequate to meet the needs of the Partnership.

Liquidity - Managing General Partner

The Managing General Partner has a highly leveraged capital structure with
$50.0 million and $123.7 million of principal due in August of 2003 and
October of 2004, respectively. The Managing General Partner will incur
approximately $17.6 million in interest payments in 2002 on its debt
obligations. Due to the depressed commodity prices experienced during the
last quarter of 2001, the Managing General Partner is experiencing
difficulty in generating sufficient cash flow to meet its obligations and
sustain its operations. The Managing General Partner is currently in the
process of renegotiating the terms of its various obligations with its
creditors and/or attempting to seek new lenders or equity investors.
Additionally, the Managing General Partner would consider disposing of
certain assets in order to meet its obligations.

There can be no assurance that the Managing General Partner's debt
restructuring efforts will be successful or that the lenders will agree to
a course of action consistent with the Managing General Partners
requirements in restructuring the obligations. Even if such agreement is
reached, it may require approval of additional lenders, which is not
assured. Furthermore, there can be no assurance that the sales of assets
can be successfully accomplished on terms acceptable to the Managing
General Partner. Under current circumstances, the Managing General
Partner's ability to continue as a going concern depends upon its ability
to (1) successfully restructure its obligations or obtain additional
financing as may be required, (2) maintain compliance with all debt
covenants, (3) generate sufficient cash flow to meet its obligations on a
timely basis, and (4) achieve satisfactory levels of future earnings. If
the Managing General Partner is unsuccessful in its efforts, it may be
unable to meet its obligations making it necessary to undertake such other
actions as may be appropriate to preserve asset values. Upon the
occurrence of any event of dissolution by the Managing General Partner, the
holders of a majority of limited partnership interests may, by written
agreement, elect to continue the business of the Partnership in the
Partnership's name, with Partnership property, in a reconstituted
partnership under the terms of the partnership agreement and to designate a
successor Managing General Partner.


Recent Accounting Pronouncements

In June 1998, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No.133, "Accounting
for Derivative Instruments and Hedging Activities." SFAS No. 133, as
amended by SFAS No. 138, establishes accounting and reporting standards for
derivative instruments, including certain derivative instruments embedded
in other contracts and for hedging activities. Assessment by the Managing
General Partner revealed this pronouncement to have no impact on the
partnerships.

The FASB has issued Statement No. 143 "Accounting for Asset Retirement
Obligations" which establishes requirements for the accounting of removal-
type costs associated with asset retirements. The standard is effective
for fiscal years beginning after June 15, 2002, with earlier application
encouraged. The Managing General Partner is currently assessing the impact
on the partnerships financial statements.

On October 3, 2001, the FASB issued Statements No. 144 "Accounting for the
Impairment or Disposal of Long-Lived Assets." This pronouncement
supercedes FAS 121 "Accounting for the Impairment of Long-Lived Assets and
for Long-Lived Assets to Be Disposed" and eliminates the requirement of
Statement 121 to allocate goodwill to long-lived assets to be tested for
impairment. The provisions of this statement are effective for financial
statements issued for fiscal years beginning after December 15, 2001, and
interim periods within those fiscal years. The Managing General Partner is
currently assessing the impact to the partnerships financial statements.

(a Delaware limited partnership)

Notes to Financial Statements

1. Organization
Southwest Royalties Institutional Income Fund VII-B, L.P. was
organized under the laws of the state of Delaware on January 28, 1987,
for the purpose of acquiring producing oil and gas properties and to
produce and market crude oil and natural gas produced from such
properties for a term of 50 years, unless terminated at an earlier
date as provided for in the Partnership Agreement. The Partnership
sells its oil and gas production to a variety of purchasers with the
prices it receives being dependent upon the oil and gas economy.
Southwest Royalties, Inc. serves as the Managing General Partner and
H. H. Wommack, III, as the individual general partner. Effective
December 31, 2001, Mr. Wommack sold his general partner interest to
the Managing General Parnter. Revenues, costs and expenses are
allocated as follows:

Limited General
Partners Partners
-------- --------
Interest income on capital contributions 100% -
Oil and gas sales 90% 10%
All other revenues 90% 10%
Organization and offering costs (1) 100% -
Syndication costs 100% -
Amortization of organization costs 100% -
Property acquisition costs 100% -
Gain/loss on property disposition 90% 10%
Operating and administrative costs (2) 90% 10%
Depreciation, depletion and amortization of
oil and gas properties 90% 10%
All other costs 90% 10%

(1)All organization costs in excess of 3% of initial capital
contributions will be paid by the Managing General Partner and
will be treated as a capital contribution. The Partnership paid
the Managing General Partner an amount equal to 3% of initial
capital contributions for such organization costs.

(2)Administrative costs in any year which exceed 2% of capital
contributions shall be paid by the Managing General Partner and
will be treated as a capital contribution.

2. Summary of Significant Accounting Policies

Oil and Gas Properties
Oil and gas properties are accounted for at cost under the full-cost
method. Under this method, all productive and nonproductive costs
incurred in connection with the acquisition, exploration and
development of oil and gas reserves are capitalized. Gain or loss on
the sale of oil and gas properties is not recognized unless
significant oil and gas reserves are involved.

The Partnership's policy for depreciation, depletion and amortization
of oil and gas properties is computed under the units of revenue
method. Under the units of revenue method, depreciation, depletion
and amortization is computed on the basis of current gross revenues
from production in relation to future gross revenues, based on current
prices, from estimated production of proved oil and gas reserves.

Under the units of revenue method, the Partnership computes the
provision by multiplying the total unamortized cost of oil and gas
properties by an overall rate determined by dividing (a) oil and gas
revenues during the period by (b) the total future gross oil and gas
revenues as estimated by the Partnership's independent petroleum
consultants. It is reasonably possible that those estimates of
anticipated future gross revenues, the remaining estimated economic
life of the product, or both could be changed significantly in the
near term due to the potential fluctuation of oil and gas prices or
production. The depletion estimate would also be affected by this
change.

Notes to Financial Statements

2. Summary of Significant Accounting Policies - continued

Oil and Gas Properties - continued
Should the net capitalized costs exceed the estimated present value of
oil and gas reserves, discounted at 10%, such excess costs would be
charged to current expense. As of December 31, 2001, 2000 and 1999,
the net capitalized costs did not exceed the estimated present value
of oil and gas reserves.

The Partnership's interest in oil and gas properties consists of net
profits interests in proved properties located within the continental
United States. A net profits interest is created when the owner of a
working interest in a property enters into an arrangement providing
that the net profits interest owner will receive a stated percentage
of the net profit from the property. The net profits interest owner
will not otherwise participate in additional costs and expenses of the
property.

Estimates and Uncertainties
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. The Partnerships depletion
calculation and full-cost ceiling test for oil and gas properties uses
oil and gas reserves estimates, which are inherently imprecise.
Actual results could differ from those estimates.

Syndication Costs
Syndication costs are accounted for as a reduction of partnership
equity.

Environmental Costs
The Partnership is subject to extensive federal, state and local
environmental laws and regulations. These laws, which are constantly
changing, regulate the discharge of materials into the environment and
may require the Partnership to remove or mitigate the environmental
effects of the disposal or release of petroleum or chemical substances
at various sites. Environmental expenditures are expended or
capitalized depending on their future economic benefit. Costs which
improve a property as compared with the condition of the property when
originally constructed or acquired and costs which prevent future
environmental contamination are capitalized. Expenditures that relate
to an existing condition caused by past operations and that have no
future economic benefits are expended. Liabilities for expenditures
of a non-capital nature are recorded when environmental assessment
and/or remediation is probable, and the costs can be reasonably
estimated.

Gas Balancing
The Partnership utilizes the sales method of accounting for gas-
balancing arrangements. Under this method the Partnership recognizes
sales revenue on all gas sold. As of December 31 2001 and 2000, the
Partnership was under produced by 3,056 mcf and 332 mcf of gas. As of
December 31 1999, the Partnership was over produced by 1,214 mcf of
gas.

Income Taxes
No provision for income taxes is reflected in these financial
statements, since the tax effects of the Partnership's income or loss
are passed through to the individual partners.

In accordance with the requirements of Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes, the
Partnership's tax basis in its net oil and gas properties at December
31, 2001 and 2000 is $281,380 and $311,625 less than that shown on the
accompanying Balance Sheets in accordance with generally accepted
accounting principles.

Notes to Financial Statements

2. Summary of Significant Accounting Policies - continued

Cash and Cash Equivalents
For purposes of the statement of cash flows, the Partnership considers
all highly liquid debt instruments purchased with a maturity of three
months or less to be cash equivalents. The Partnership maintains its
cash at one financial institution.

Number of Limited Partner Units
As of December 31, 2001, 2000 and 1999, there were 15,000 limited
partner units outstanding held by 718, 769 and 871.

Concentrations of Credit Risk
The Partnership is subject to credit risk through trade receivables.
Although a substantial portion of its debtors' ability to pay is
dependent upon the oil and gas industry, credit risk is minimized due
to a large customer base. All partnership revenues are received by
the Managing General Partner and subsequently remitted to the
partnership and all expenses are paid by the Managing General Partner
and subsequently reimbursed by the partnership.

Fair Value of Financial Instruments
The carrying amount of cash and accounts receivable approximates fair
value due to the short maturity of these instruments.

Net Income (loss) per limited partnership unit
The net income (loss) per limited partnership unit is calculated by
using the number of outstanding limited partnership units.

Recent Accounting Pronouncements
In June 1998, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No.133,
"Accounting for Derivative Instruments and Hedging Activities." SFAS
No. 133, as amended by SFAS No. 138, establishes accounting and
reporting standards for derivative instruments, including certain
derivative instruments embedded in other contracts and for hedging
activities. Assessment by the Managing General Partner revealed this
pronouncement to have no impact on the partnerships.

The FASB has issued Statement No. 143 "Accounting for Asset Retirement
Obligations" which establishes requirements for the accounting of
removal-type costs associated with asset retirements. The standard is
effective for fiscal years beginning after June 15, 2002, with earlier
application encouraged. The Managing General Partner is currently
assessing the impact on the partnerships financial statements.

On October 3, 2001, the FASB issued Statements No. 144 "Accounting for
the Impairment or Disposal of Long-Lived Assets." This pronouncement
supercedes FAS 121 "Accounting for the Impairment of Long-Lived Assets
and for Long-Lived Assets to Be Disposed" and eliminates the
requirement of Statement 121 to allocate goodwill to long-lived assets
to be tested for impairment. The provisions of this statement are
effective for financial statements issued for fiscal years beginning
after December 15, 2001, and interim periods within those fiscal
years. The Managing General Partner is currently assessing the impact
to the partnerships financial statements.

Notes to Financial Statements

3. Liquidity - Managing General Partner
The Managing General Partner has a highly leveraged capital structure
with $50.0 million and $123.7 million of principal due in August of
2003 and October of 2004, respectively. The Managing General Partner
will incur approximately $17.6 million in interest payments in 2002 on
its debt obligations. Due to the depressed commodity prices
experienced during the last quarter of 2001, the Managing General
Partner is experiencing difficulty in generating sufficient cash flow
to meet its obligations and sustain its operations. The Managing
General Partner is currently in the process of renegotiating the terms
of its various obligations with its creditors and/or attempting to
seek new lenders or equity investors. Additionally, the Managing
General Partner would consider disposing of certain assets in order to
meet its obligations.

There can be no assurance that the Managing General Partner's debt
restructuring efforts will be successful or that the lenders will
agree to a course of action consistent with the Managing General
Partners requirements in restructuring the obligations. Even if such
agreement is reached, it may require approval of additional lenders,
which is not assured. Furthermore, there can be no assurance that the
sales of assets can be successfully accomplished on terms acceptable
to the Managing General Partner. Under current circumstances, the
Managing General Partner's ability to continue as a going concern
depends upon its ability to (1) successfully restructure its
obligations or obtain additional financing as may be required, (2)
maintain compliance with all debt covenants, (3) generate sufficient
cash flow to meet its obligations on a timely basis, and (4) achieve
satisfactory levels of future earnings. If the Managing General
Partner is unsuccessful in its efforts, it may be unable to meet its
obligations making it necessary to undertake such other actions as may
be appropriate to preserve asset values. Upon the occurrence of any
event of dissolution by the Managing General Partner, the holders of a
majority of limited partnership interests may, by written agreement,
elect to continue the business of the Partnership in the Partnership's
name, with Partnership property, in a reconstituted partnership under
the terms of the partnership agreement and to designate a successor
Managing General Partner.

4. Commitments and Contingent Liabilities
After completion of the Partnership's first full fiscal year of
operations and each year thereafter, the Managing General Partner has
offered and will continue to offer to purchase each limited partner's
interest in the Partnership, at a price based on tangible assets of
the Partnership, plus the present value of the future net revenues of
proved oil and gas properties, minus liabilities with a risk factor
discount of up to one-third which may be implemented in the sole
discretion of the Managing General Partner. However, the Managing
General Partner's obligation to purchase limited partner units is
limited to an expenditure of an amount not in excess of 10% of the
total limited partner units initially subscribed for by limited
partners.

The Partnership is subject to various federal, state and local
environmental laws and regulations which establish standards and
requirements for protection of the environment. The Partnership
cannot predict the future impact of such standards and requirements,
which are subject to change and can have retroactive effectiveness.
The Partnership continues to monitor the status of these laws and
regulations.

As of December 31, 2001, the Partnership has not been fined, cited or
notified of any environmental violations and management is not aware
of any unasserted violations which would have a material adverse
effect upon capital expenditures, earnings or the competitive position
in the oil and gas industry. However, the Managing General Partner
does recognize by the very nature of its business, material costs
could be incurred in the near term to bring the Partnership into total
compliance. The amount of such future expenditures is not
determinable due to several factors, including the unknown magnitude
of possible contaminations, the unknown timing and extent of the
corrective actions which may be required, the determination of the
Partnership's liability in proportion to other responsible parties and
the extent to which such expenditures are recoverable from insurance
or indemnifications from prior owners of Partnership's properties.

5. Related Party Transactions
A significant portion of the oil and gas properties in which the
Partnership has an interest are operated by and purchased from the
Managing General Partner. As provided for in the operating agreement
for each respective oil and gas property in which the Partnership has
an interest, the operator is paid an amount for administrative
overhead attributable to operating such properties, with such amounts
to Southwest Royalties, Inc. as operator approximating $19,800,
$19,400 and $19,400 for the years ended December 31, 2001, 2000 and
1999, respectively. In addition, the Managing General Partner and
certain officers and employees may have an interest in some of the
properties that the Partnership also participates.

Certain subsidiaries or affiliates of the Managing General Partner
perform various oilfield services for properties in which the
Partnership owns an interest. Such services aggregated approximately
$11,000, $9,100 and $3,500 for the years ended December 31, 2001, 2000
and 1999, respectively.

Southwest Royalties, Inc., the Managing General Partner, was paid
$108,000 during 2001, 2000 and 1999 as an administrative fee for
indirect general and administrative overhead expenses.

Receivables from Southwest Royalties, Inc., the Managing General
Partner, of approximately $71,400 and $190,200 are from oil and gas
production, net of lease operating costs and production taxes, as of
December 31, 2001 and 2000, respectively.

In addition, a director and officer of the Managing General Partner is
a partner in a law firm, with such firm providing legal services to
the Partnership. There were no legal services for the year ended
December 31, 2001. Legal services for the years ended December 31,
2000 and 1999 were approximately $100 and $200, respectively.

6. Major Customers
No material portion of the Partnership's business is dependent on a
single purchaser, or a very few purchasers, where the loss of one
would have a material adverse impact on the Partnership. Four
purchasers accounted for 66% of the Partnership's total oil and gas
production during 2001: Equiva Trading Company for 23%, Duke Energy
Field Services for 21%, BP Amoco for 11% and Plains Marketing LP for
11%. Four purchasers accounted for 77% of the Partnership's total oil
and gas production during 2000: Phillips 66 Natural Gas Co. for 28%,
Equiva Trading Company for 19%, BP Amoco for 17% and Plains Marketing
LP for 13%. Four purchasers accounted for 74% of the Partnership's
total oil and gas production during 1999: Phillips 66 Natural Gas Co.
for 27%, Equiva Trading Company for 19%, Amoco Production for 17% and
Scurlock Permian LLC. for 11%. All purchasers of the Partnership's
oil and gas production are unrelated third parties. In the event any
of these purchasers were to discontinue purchasing the Partnership's
production, the Managing General Partner believes that a substitute
purchaser or purchasers could be located without undue delay. No
other purchaser accounted for an amount equal to or greater than 10%
of the Partnership's sales of oil and gas production.

7. Estimated Oil and Gas Reserves (unaudited) - continued
*Ryder Scott Petroleum Engineers prepared the reserve and present
value data for the Partnership's existing properties as of January 1,
2002. The reserve estimates were made in accordance with guidelines
established by the Securities and Exchange Commission pursuant to Rule
4-10(a) of Regulation S-X. Such guidelines require oil and gas
reserve reports be prepared under existing economic and operating
conditions with no provisions for price and cost escalation except by
contractual arrangements.

Oil price adjustments were made in the individual evaluations to
reflect oil quality, gathering and transportation costs. The results
of the reserve report as of January 1, 2002 are an average price of
$17.99 per barrel.

Gas price adjustments were made in the individual evaluations to
reflect BTU content, gathering and transportation costs and gas
processing and shrinkage. The results of the reserve report as of
January 1, 2002 are an average price of $2.21 per Mcf.

The evaluation of oil and gas properties is not an exact science and
inevitably involves a significant degree of uncertainty, particularly
with respect to the quantity of oil or gas that any given property is
capable of producing. Estimates of oil and gas reserves are based on
available geological and engineering data, the extent and quality of
which may vary in each case and, in certain instances, may prove to be
inaccurate. Consequently, properties may be depleted more rapidly
than the geological and engineering data have indicated.

Unanticipated depletion, if it occurs, will result in lower reserves
than previously estimated; thus an ultimately lower return for the
Partnership. Basic changes in past reserve estimates occur annually.
As new data is gathered during the subsequent year, the engineer must
revise his earlier estimates. A year of new information, which is
pertinent to the estimation of future recoverable volumes, is
available during the subsequent year evaluation. In applying industry
standards and procedures, the new data may cause the previous
estimates to be revised. This revision may increase or decrease the
earlier estimated volumes. Pertinent information gathered during the
year may include actual production and decline rates, production from
offset wells drilled to the same geologic formation, increased or
decreased water production, workovers, and changes in lifting costs,
among others. Accordingly, reserve estimates are often different from
the quantities of oil and gas that are ultimately recovered.

The Partnership has reserves which are classified as proved developed
producing, proved developed non-producing and proved undeveloped. All
of the proved reserves are included in the engineering reports which
evaluate the Partnership's present reserves.

Because the Partnership does not engage in drilling activities, the
development of proved undeveloped reserves is conducted pursuant to
farmout arrangements with the Managing General Partner or unrelated
third parties. Generally, the Partnership retains a carried interest
such as an overriding royalty interest under the terms of a farmout,
or receives cash.

Item 13. Certain Relationship and Related Transactions

In 2001, the Managing General Partner received $108,000 as an
administrative fee. This amount is part of the general and administrative
expenses incurred by the Partnership.

In some instances the Managing General Partner and certain officers and
employees may be working interest owners in an oil and gas property in
which the Partnership also has a net profits interest. Certain properties
in which the Partnership has an interest are operated by the Managing
General Partner, who was paid approximately $19,800 for administrative
overhead attributable to operating such properties during 2001.

Certain subsidiaries or affiliates of the Managing General Partner perform
various oilfield services for properties in which the Partnership owns an
interest. Such services aggregated approximately $11,000 for the year
ended December 31, 2001.

The law firm of Baker, Donelson, Bearman & Caldwell of which H. Allen
Corey, an officer and director of the Managing General Partner, is a
partner, is counsel to the Partnership. There were no legal services
rendered by Baker, Donelson, Bearman & Caldwell to the Partnership during
2001, which constitutes an immaterial portion of that firm's business.

In the opinion of management, the terms of the above transactions are
similar to ones with unaffiliated third parties.
