PART I

ITEM 1. BUSINESS

Mewbourne Energy Partners 00-A, L.P. (the "Registrant") is a limited partnership
organized under the laws of the State of Delaware on February 15, 2000 (date of
inception). Its managing general partner is Mewbourne Development Corporation, a
Delaware corporation ("MD").

A Registration Statement was filed pursuant to the Securities Act of 1933, as
amended, registering limited partnership interests aggregating $4,000,000 and
$16,000,000 in general partnership interests in a series of Delaware limited
partnerships formed under Mewbourne Energy 99-00 Drilling Programs. The
Registrant was declared effective by the Securities and Exchange Commission on
May 5, 2000. On October 31, 2000, the offering of limited and general
partnership interests in the Registrant was closed, with interests aggregating
$10,000,000 being sold to 354 subscribers of which $9,518,000 were sold to 334
subscribers as general partner interests and $482,000 were sold to 20
subscribers as limited partner interests.

The Registrant engages primarily in oil and gas development and production and
is not involved in any other industry segment. See the selected financial data
in Item 6 and the financial statements in Item 8 of this report for a summary of
the Registrant's revenue, income and identifiable assets.

The Registrant has acquired interests in oil and gas prospects for the purpose
of development drilling. At December 31, 2002, 30 wells had been drilled and
were productive and two wells were drilled and abandoned. Of the 30 productive
wells, 27 were producing and 3 were plugged and abandoned at December 31, 2002.
The following table summarizes the Registrant's drilling activity for the years
ended December 31, 2002 and 2001, and for the period from February 15, 2000
(date of inception) through December 31, 2000:




2002 2001 2000
----------- ------------ ------------
Gross Net Gross Net Gross Net
----- ---- ----- ----- ----- -----

Development Wells:
Oil and natural gas wells 2 .157 22 5.108 6 1.293
Non-productive wells 0 0 0 0 2 .600


The sale of crude oil and natural gas produced by the Registrant will be
affected by a number of factors that are beyond the Registrant's control. These
factors include the price of crude oil and natural gas, the fluctuating supply
of and demand for these products, competitive fuels, refining, transportation,
extensive federal and state regulations governing the production and sale of
crude oil and natural gas, and other competitive conditions. It is impossible to
predict with any certainty the future effect of these factors on the Registrant.

The Registrant does not have long-term contracts with purchasers of its crude
oil or natural gas. The market for crude oil is such that the Registrant
anticipates it will be able to sell all the crude oil it can produce. Natural
gas will be sold to local distribution companies, gas marketers and end users on
the spot market. The spot market reflects immediate sales of natural gas without
long-term contractual commitments. The future market condition for natural gas
cannot be predicted with any certainty, and the Registrant may experience delays
in marketing natural gas production and fluctuations in natural gas prices.



2


Many aspects of the Registrant's activities are highly competitive including,
but not limited to, the acquisition of suitable drilling prospects and the
procurement of drilling and related oil field equipment, and are subject to
governmental regulation, both at Federal and state levels. The Registrant's
ability to compete depends on its financial resources and on the managing
general partner's staff and facilities, none of which are significant in
comparison with those of the oil and gas exploration, development and production
industry as a whole. Federal and state regulation of oil and gas operations
generally includes drilling and spacing of wells on producing acreage, the
imposition of maximum allowable production rates, the taxation of income and
other items, and the protection of the environment.

The Registrant does not have any employees of its own. MD is responsible for all
management functions. Mewbourne Oil Company ("MOC"), a wholly owned subsidiary
of Mewbourne Holdings, Inc., which is also the parent of the Registrant's
managing general partner, has been appointed Program Manager and is responsible
for activities in accordance with a Drilling Program Agreement entered into by
the Registrant, MD and MOC. At March 28, 2003, MOC employed 121 persons, many of
whom dedicated a part of their time to the conduct of the Registrant's business
during the period for which this report is filed.

The production of oil and gas is not considered subject to seasonal factors
although the price received by the Registrant for natural gas sales will tend to
increase during the winter months. Order backlog is not pertinent to the
Registrant's business.

ITEM 2. PROPERTIES

The Registrant's properties consist primarily of leasehold interests in
properties on which oil and gas wells-in-progress are located. Such property
interests are often subject to landowner royalties, overriding royalties and
other oil and gas leasehold interests.

Fractional working interests in developmental oil and gas prospects located
primarily in the Anadarko Basin of Western Oklahoma, the Texas Panhandle and
Kansas, and the Permian Basin of New Mexico and West Texas, were acquired by the
Registrant, resulting in the Registrant's participation in the drilling of oil
and gas wells. At December 31, 2002, 30 wells had been drilled and were
productive and two wells were drilled and abandoned. Of the 30 productive wells,
27 were producing and 3 were plugged and abandoned at December 31, 2002.

Reserve estimates were prepared by Forrest A Garb & Associates, Inc., the
Registrant's independent petroleum consultants, in accordance with guidelines
established by the Securities and Exchange Commission.

ITEM 3. LEGAL PROCEEDINGS

The Registrant is not aware of any pending legal proceedings to which it 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 period ended
December 31, 2002 covered by this report.

PART II

ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS

At March 28, 2003, the Registrant had 10,000 outstanding limited and general
partnership interests held of record by 354 subscribers. There is no established
public or organized trading market for the limited and general partnership
interests.

Revenues which, in the sole judgement of the managing general partner, are not
required to meet the Registrant's obligations will be distributed to the
partners at least quarterly in accordance with the Registrant's Partnership
Agreement. Distributions made to limited and general partners during the years
ended December 31, 2002 and December 31, 2001, were $1,500,995 and $3,330,000
respectively.

ITEM 6. SELECTED FINANCIAL DATA

The following table sets forth selected financial data for the years ended
December 31, 2002 and 2001, and for the period from February 15, 2000 (date of

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

General

Mewbourne Energy Partners 00-A, L.P. (the "Registrant") was organized as a
Delaware limited partnership on February 15, 2000. The offering of limited and
general partner interests began May 5, 2000 as part of an offering registered
under the name Mewbourne Energy 99-00 Drilling Programs. The offering of limited
and general partner interests in the Registrant concluded October 31, 2000, with
total investor partner contributions of $10,000,000.

The Registrant was formed to engage primarily in the business of drilling
development wells, to produce and market crude oil and natural gas produced from
such properties, to distribute any net proceeds from operations to the general
and limited partners and to the extent necessary, acquire leases which contain
drilling prospects. The economic life of the Registrant depends on the period
over which the Registrant's oil and gas reserves are economically recoverable.

Results of Operations

The following table sets forth certain operating data for the years ended
December 31, 2002 and 2001, and for the period from February 15, 2000 (date of
inception) through December 31, 2000:




2002 2001 2000

Production:
Natural gas (MMcf) 572 1,141 9
Oil (MBbl) 11 8 .2
Natural gas equivalent (MMcfe) 638 1,188 10

Average sales price per unit
Natural gas (per Mcf) $ 2.93 $ 3.71 $ 8.58
Oil (per Bbl) 25.36 24.55 27.66

Production taxes .24 .28 .63
Administrative and general .12 .13 .06
Depreciation, depletion and amortization 1.08 1.55 2.71
Cost ceiling write-down -- 2.75 --


Note: The Partnership was formed during the year 2000 and began drilling oil and
gas wells. The majority of the wells were not drilled or completed until 2001
which accounts for the substantial increase in sales and production volumes
during the year ended December 31, 2001.

Year ended December 31, 2002 compared to the year ended December 31, 2001

Oil and natural gas sales. Oil and natural gas sales decreased to $1,955,985 in
2002 from $4,419,274 in 2001. Production volumes decreased to 571,547 Mcf of gas
in 2002 from 1,141,023 Mcf in 2001, while oil volumes increased to 10,989 Bbls
in 2002 from 7,826 Bbls in 2001. Oil and gas revenues declined primarily due to
one well located in western Oklahoma. The well began producing at a high rate of
production in 2001 and rapidly declined. The production rate is beginning to
stabilize, therefore, future oil and gas revenues should also begin to stabilize
subject to normal declines and price variations. A decrease in the price of gas
also contributed significantly to the decline in oil and gas revenues.

Interest income. Interest income decreased from $47,646 in 2001 to $4,782 in
2002 due to expenditures for the drilling of oil and gas wells, which resulted
in a decrease of capital available for investments.

Lease operating expense and production taxes. Lease operating expense increased
from $265,560 in 2001 to $359,649 in 2002. This expense increased due to
increased ad valorem taxes, additional new wells, workover of existing wells,
and increased compressor charges in 2002. Production taxes decreased from
$333,883 in 2001 to $151,292 in 2002. This expense decreased due to production
decreases.


5


Depreciation, depletion and amortization. Depreciation, depletion and
amortization decreased from $1,846,113 in 2001 to $691,224 in 2002. The decrease
is primarily due to the decline in production volumes and the reduction in oil
and gas properties resulting from the cost ceiling write-down in 2001.

Cost ceiling write-down. A cost ceiling write-down of $3,271,996 was recorded in
2001 primarily due to a decrease in the year end price of an Mcf of natural gas
from $9.13 in 2000 to $2.27 in 2001.

Year ended December 31, 2001 compared to the period from February 15, 2000 (date
of inception) through December 31, 2000

Oil and natural gas sales. Oil and natural gas sales increased to $4,419,274 in
2001 from $83,611 in 2000 due to additional wells being drilled and completed by
the Partnership during 2001, which resulted in a substantial increase in sales
revenues and production volumes. Production volumes increased to 1,141,023 Mcf
of gas in 2001 from 8,944 Mcf in 2000, while oil volumes increase to 7,826 Bbls
in 2001 from 249 Bbls in 2000.

Interest income. Interest income decreased from $81,924 in 2000 to $ 47,646 in
2001 due to expenditures for the drilling of oil and gas wells, which resulted
in a decrease of capital available for investments.

Lease operating expense and production taxes. Lease operating expense increased
from $929 in 2000 to $265,560 in 2001. Production taxes increased from $6,546 in
2000 to $333,883 in 2001. These expenses increased as additional wells were
drilled and completed in 2001.

Depreciation, depletion and amortization. Depreciation, depletion and
amortization increased from $28,285 in 2000 to $1,846,113 in 2001 as additional
wells were drilled and producing and therefore depleting their reserves.

Cost ceiling write-down. A cost ceiling write-down of $3,271,996 was recorded in
2001 primarily due to a decrease in the year end price of an Mcf of natural gas
from $9.13 in 2000 to $2.27 in 2001.

Liquidity and capital resources

Net cash decreased by $678,106 during the year ended December 31, 2002. Cash
flows from operating activities were offset by funds utilized primarily for
drilling and completion costs and cash distributions to partners. All wells for
which funds have been committed have been drilled, therefore, future capital
requirements are not expected to be material in nature and will be paid with
revenues generated through oil and gas sales.

Net cash decreased by $1,894,661 during the year ended December 31, 2001. These
funds were utilized primarily for drilling and completion costs.

Critical Accounting Policies

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.

Significant estimates inherent in the Registrant's financial statements include
the estimate of oil and gas reserves as reported in the footnotes to the
financial statements. Changes in oil and gas prices, changes in production
estimates and the success or failure of future development activities could have
a significant effect on reserve estimates. The reserve estimates directly impact
the computation of depreciation, depletion and amortization, and the ceiling
test for the Registrants oil and gas properties.

The Registrant follows the full-cost method of accounting for its oil and gas
activities. Under the full-cost method, all productive and nonproductive costs
incurred in the acquisition, exploration and development of oil and gas
properties are capitalized. Depreciation, depletion and amortization of oil and
gas properties subject to amortization is computed on the units-of-production
method based on the proved reserves underlying the oil and gas properties. Oil
and gas properties are subject to an annual ceiling test that limits such costs
to the aggregate of the present value of future net cash flows of proved
reserves and the lower of cost or fair value of unproved properties.

All financing activities of the Registrant are reported in the financial
statements. The Registrant does not engage in any off-balance sheet financing
arrangements.

In June 2001, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 143 (FAS 143), Accounting for Asset
Retirement Obligations. This statement changes financial accounting and
reporting for obligations associated with the retirement and disposal of
long-lived assets and the associated asset retirement costs and is effective for
the Partnership beginning January 1, 2003. The Partnership is currently
evaluating the effect of adopting FAS 143.

In June 2002, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 146 (FAS 146), Accounting for Costs
Associated with Exit or Disposal Activities. This Statement addresses financial
accounting and reporting for costs associated with exit or disposal activities
and is effective for the Partnership beginning January 1, 2003. The adoption of
FAS 146 is not expected to have a material impact on the Partnership's financial
statements.

MEWBOURNE ENERGY PARTNERS 00-A, L.P.
NOTES TO FINANCIAL STATEMENTS


1. Significant Accounting Policies:

Accounting for Oil and Gas Producing Activities

Mewbourne Energy Partners 00-A, L.P., (the "Partnership"), a Delaware limited
partnership engaged primarily in oil and gas development and production in
Texas, Oklahoma, New Mexico and Kansas, was organized on February 15, 2000. The
offering of limited and general partnership interests began May 5, 2000 as a
part of an offering registered under the name Mewbourne Energy Partners 99-00
Drilling Programs, (the "Program"), and concluded October 31, 2000, with total
investor contributions of $10,000,000 being sold to 354 subscribers of which
$9,518,000 were sold to 334 subscribers as general partner interests and
$482,000 were sold to 20 subscribers as limited partner interests.

The Program's sole business is the development and production of oil and gas
with a concentration on gas. Substantially all of the Program's gas reserves are
being sold regionally in the spot market. Due to the highly competitive nature
of the spot market, prices 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 prices received for the Program's oil and gas are subject to
influences such as global consumption and supply trends.

The Partnership follows the full-cost method of accounting for its oil and gas
activities. Under the full-cost method, all productive and nonproductive costs
incurred in the acquisition, exploration and development of oil and gas
properties are capitalized. Depreciation, depletion and amortization of oil and
gas properties subject to amortization is computed on the units-of-production
method based on the proved reserves underlying the oil and gas properties. No
capitalized costs were excluded from amortization for the years ended December
31, 2002 and 2001. Gains and losses on the sale or other disposition of
properties are not recognized unless such adjustments would significantly alter
the relationship between capitalized costs and the proved oil and gas reserves.
Capitalized costs are subject to an annual ceiling test that limits such costs
to the aggregate of the present value of future net cash flows of proved
reserves and the lower of cost or fair value of unproved properties. A cost
ceiling write-down of $3,271,996 was recorded for the year ended December 31,
2001.

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.

Cash and cash equivalents

The Partnership considers all highly liquid investments, those with original
maturities of three months or less at the date of acquisition, to be cash
equivalents.

The Partnership maintains all its cash in one financial institution.

Oil and Gas Sales

The Program's oil and condensate production is sold, title passed, and revenue
recognized at or near the Program's wells under short-term purchase contracts at
prevailing prices in accordance with arrangements which are customary in the oil
industry. Sales of gas

19


applicable to the Program's interest are recorded as revenue when the gas is
metered and title transferred pursuant to the gas sales contracts covering the
Program's interest in gas reserves. The Partnership uses the sales method to
recognize oil and gas revenue whereby revenue is recognized for the amount of
production taken regardless of the amount for which the Partnership is entitled
based on its working interest ownership. As of December 31, 2002 and 2001, no
material gas imbalances between the Partnership and other working interest
owners existed.

Income Taxes

The Partnership is treated as a partnership for income tax purposes, and as a
result, income of the Partnership is reported on the tax returns of the partners
and no recognition is given to income taxes in the financial statements.

Reclassifications

Certain reclassifications have been made to the prior year balances to conform
to current year presentation.

2. Organization and Related Party Transactions:

The Partnership was organized on February 15, 2000. Mewbourne Development
Corporation (MD) is managing general partner and Mewbourne Oil Company (MOC) is
operator of oil and gas properties owned by the Partnership. Mewbourne Holdings,
Inc. is the parent of both MD and MOC. Substantially all transactions are with
MD and MOC.

Reimbursement to MOC for supervision and other operator charges totaled
$175,577, $614,646 and $77,393 for the years ended December 31, 2002 and 2001,
and for the period from February 15, 2000 (date of inception) through December
31, 2000, respectively. Services and operator charges are billed in accordance
with the program and partnership agreements.

In general, during any particular calendar year the total amount of
administrative expenses allocated to the Partnership shall not exceed the
greater of (a) 3.5% of the Partnership's gross revenue from the sale of oil and
natural gas production during each year (calculated without any deduction for
operating costs or other costs and expenses) or (b) the sum of $50,000 plus .25%
of the capital contributions of limited and general partners. Under this
arrangement, $62,253, $140,581, and $0 were allocated to the Partnership during
the years ended December 31, 2002 and 2001, and for the period from February 15,
2000 (date of inception) through December 31, 2000, respectively.

The Partnership participates in oil and gas activities through an income tax
partnership, the Program. The Partnership and MD are parties to the Program
agreement. The costs and revenues of the Program are allocated to MD and the
Partnership as follows:




Partnership MD
----------- ----

Revenues:
Proceeds from disposition of depreciable and
depletable properties 60% 40%
All other revenues 60% 40%

Costs and expenses:
Organization and offering costs (1) 0% 100%
Lease acquisition costs (1) 0% 100%
Tangible and intangible drilling costs (1) 100% 0%
Operating costs, reporting and legal
expenses, general and administrative
expenses and all other costs 60% 40%




20



(1) As noted above, pursuant to the Program, MD must contribute 100% of
organization and offering costs and lease acquisition costs which will
approximate 30% of total capital costs. To the extent that organization and
offering costs and lease acquisition costs are less that 30% of total capital
costs, MD is responsible for tangible drilling costs until its share of the
Program's total capital costs reaches approximately 30%.

The partnership's financial statements reflect its respective proportionate
interest in the Program.

3. Reconciliation of Net Income (Loss) Per Statements of Income (Loss)
With Net Income (Loss) Per Federal Income Tax Return:

The following is a reconciliation of net income (loss) per statements of income
(loss) with the net income (loss) per federal income tax return for the years
ended December 31, 2002 and 2001, and for the period from February 15, 2000
(date of inception) through December 31, 2000:




2002 2001 2000


Net income (loss)per statement of income (loss) $ 679,468 $ (1,400,495) $ 129,107

Intangible development costs capitalized for
financial reporting purposes and expensed

------------- ------------- -------------
Net income (loss) per federal income tax return
before tentative tax depletion $ 530,225 $ 2,171,312 $ (6,767,236)
============= ============= =============



The Partnership's financial reporting bases of its net assets exceeded the tax
bases of its net assets by $3,476,392, $3,324,536, and $6,896,343 at December
31, 2002 and 2001, and for the period from February 15, 2000 (date of inception)
through December 31, 2000, respectively.

4. Recently Issued Accounting Standards:

In June 2001, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 143 (FAS 143), Accounting for Asset
Retirement Obligations. This statement changes financial accounting and
reporting for obligations associated with the retirement and disposal of
long-lived assets and the associated asset retirement costs and is effective for
the Partnership beginning January 1, 2003. The Partnership is currently
evaluating the effect of adopting FAS 143.

In June 2002, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 146 (FAS 146), Accounting for Costs
Associated with Exit or Disposal Activities. This Statement addresses financial
accounting and reporting for costs associated with exit or disposal activities
and is effective for the Partnership beginning January 1, 2003. The adoption of
FAS 146 is not expected to have a material impact on the Partnership's financial
statements.

5. Supplemental Oil and Gas Information (Unaudited):

The tables presented below provide supplemental information about oil and
natural gas exploration and production activities as defined by SFAS No. 69,
"Disclosures about Oil an Gas Producing Activities".

Costs Incurred and Capitalized Costs:

2001, and for the period from February 15, 2000 (date of inception) through
December 31, 2000, respectively.

Although certain wells had been drilled, completed and began producing in
December 2000, a majority of the wells were drilled and completed subsequent to
December 31, 2000.

Estimated Net Quantities of Proved Oil and Gas Reserves

Reserve estimates as well as certain information regarding future production and
discounted cash flows were determined by the Partnership's independent petroleum
consultants and MOC's petroleum reservoir engineers. The Partnership considers
reserve estimates to be reasonable, however, due to inherent uncertainties and
the limited nature of reservoir data, estimates of underground reserves are
imprecise and subject to change over time as additional information becomes
available.

There have been no favorable or adverse events that have caused a significant
change in estimated proved reserves since December 31, 2002. The Partnership has
no long-term supply agreements or contracts with governments or authorities in
which it acts as producer nor does it have any interest in oil and gas
operations accounted for by the equity method. All reserves are located onshore
within the United States.

(1) All of these reserves are categorized as proved developed as of
December 31, 2002, 2001, and 2000.


Standardized Measure of Discounted Future Net Cash Flows:

For the years ended December 31, 2002 and 2001, and for the period from February
15, 2000 (date of inception) through December 31, 2000

The Standardized measure of discounted future net cash flows from estimated
production of proved oil and gas reserves is presented in accordance with the
provisions of Statement of Financial Accounting Standards No. 69, "Disclosures
about Oil and Gas Producing Activities" (SFAS No. 69). In computing this data,
assumptions other than those mandated by SFAS No. 69 could produce substantially
different results. The Partnership cautions against viewing this information as
a forecast of future economic conditions or revenues.

The standardized measure has been prepared assuming year-end selling prices,
year end development and production cost and a 10 percent annual discount rate.
No future income tax expense has been provided for the Partnership since it
