PART I

ITEM 1.

Business

Mewbourne Energy Partners 02-A, L.P. (the “Registrant” or the “Partnership”) is a limited partnership organized under the laws of the State of Delaware on February 27, 2002 (date of inception). Mewbourne Development Corporation (“MD”), a Delaware Corporation, has been appointed as the Registrant’s managing general partner. MD has no significant equity interest in the Registrant.

A Registration Statement was filed pursuant to the Securities Act of 1933, as amended, registering limited and general partnership interests in a series of two Delaware limited partnerships formed under Mewbourne Energy 02-03 Drilling Programs. General and limited partnership interests were offered at $1,000 each. The maximum offering amount was $18,000,000 (18,000 interests) per partnership. The Registration Statement was declared effective by the Securities and Exchange Commission on June 26, 2002. On October 10, 2002, the offering of limited and general partnership interests in the Registrant was closed, with interests aggregating $16,072,000 originally being sold to 647 subscribers of which $14,667,000 were sold to 597 subscribers as general partner interests and $1,405,000 were sold to 50 subscribers as limited partner interests. During 2004 all general partner equity interests were converted to limited partner equity interests.

The Registrant engages primarily in oil and gas development and production and is not involved in any other industry segment. The Program is governed by a Drilling Program Agreement between the Registrant, MD and Mewbourne Oil Company (“MOC”), the program manager and a wholly owned subsidiary of Mewbourne Holdings, Inc., which is also the parent of MD. MD does not make any capital contributions directly to the Registrant; rather, MD makes its capital contributions directly to the Program. See the financial statements in Item 8 of this report for a summary of the Registrant’s revenue, income and identifiable assets.

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 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.

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 31, 2014, MOC employed 356 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 generally tend to increase during the winter months. Order backlog is not pertinent to the Registrant’s business.

ITEM 1A.

Risk Factors

Oil and natural gas prices are volatile. A decline in prices could adversely affect the Registrant’s financial position, financial results, and cash flows.

Revenues, operating results, and profitability depend primarily upon the prices received for oil and natural gas sales. Prices also affect the amount of cash flow available for distribution. In addition, cost ceiling write-downs may be necessary in the future if prices fall significantly.

Historically, the markets for oil and natural gas have been volatile and they are likely to continue to be volatile. Wide fluctuations in oil and natural gas prices may result from relatively minor changes in the supply of and demand for oil and natural gas, market uncertainty and other factors that are beyond the Registrant’s control, including:

•

worldwide and domestic supplies of oil and natural gas;

•

weather conditions;

•

the level of consumer demand;

•

the price and availability of alternative fuels;

•

the proximity, accessibility and capacity of natural gas pipelines and other transportation facilities;

•

regional imbalances in supply and demand;

•

the price and level of foreign imports;

•

domestic and foreign governmental regulations and taxes;

•

the ability of the members of the Organization of Petroleum Exporting Countries to agree to and maintain oil price and production controls;

•

political instability or armed conflict in oil-producing regions; and

•

overall domestic and global economic conditions.

These factors and the volatility of the energy markets make it extremely difficult to predict future oil and natural gas price movements with any certainty. Declines in oil and natural gas prices would not only reduce revenue, but could reduce the amount of oil and natural gas that can be produced economically and, as a result, could have a material adverse effect on the Registrant’s financial condition, results of operations and reserves. For the year ended December 31, 2013, a 10% change in the price received for oil and gas production would have had an approximate $77,000 impact on revenue.

The actual quantities and present value of proved reserves may prove to be lower than estimated.

This report contains estimates of proved reserves. These estimates are based upon various assumptions, including assumptions required by the SEC relating to oil and natural gas prices, drilling and operating expenses, capital expenditures, taxes and availability of funds. The process of estimating oil and natural gas reserves is complex. The process involves significant decisions and assumptions in the evaluation of available geological, geophysical, engineering and economic data for each reservoir. Therefore, these estimates are inherently imprecise.

Actual future production, oil and natural gas prices, revenues, taxes, development expenditures, operating expenses and quantities of recoverable oil and natural gas reserves most likely will vary from these estimates. Such variations may be significant and could materially affect the estimated quantities and present value of proved reserves. In addition, the Registrant may adjust estimates of proved reserves to reflect production history, results of exploration and development drilling, prevailing oil and natural gas prices and other factors, many of which are beyond the Registrant’s control. The Registrant’s properties may also be susceptible to hydrocarbon drainage from production by operators on adjacent properties.

Future price declines may result in a write-down of asset carrying values.

The Registrant utilizes the full-cost method of accounting for costs related to oil and natural gas properties. Under this method, all such costs (for both productive and nonproductive properties) are capitalized and amortized on an aggregate basis over the estimated lives of the properties using the unit-of-production method. However, these capitalized costs are subject to a ceiling test which limits such pooled costs to the aggregate of the present value of future net revenues attributable to proved oil and natural gas reserves discounted at 10% plus the lower of cost or market value of unproved properties. The full-cost ceiling is evaluated at the end of each quarter using the oil and gas pricing guidelines established by the Securities and Exchange Commission. A significant decline in oil and natural gas prices from current levels, or other factors, without other mitigating circumstances, could cause a future write-down of capitalized costs and a non-cash charge against future earnings.

The Registrant’s ceiling test calculations indicated no impairment of oil and natural gas properties during the years ended December 31, 2013 and 2012.

Oil and natural gas drilling and producing operations can be hazardous and may expose the Registrant to environmental liabilities.

Oil and natural gas operations are subject to many risks, including well blowouts, cratering and explosions, pipe failure, fires, formations with abnormal pressures, uncontrollable flows of oil, natural gas, brine or well fluids, and other environmental hazards and risks. If any of these risks occurs, the Registrant could sustain substantial losses as a result of:

•

injury or loss of life;

•

severe damage to or destruction of property, natural resources and equipment;

•

pollution or other environmental damage;

•

clean-up responsibilities;

•

regulatory investigations and administrative, civil and criminal penalties; and

•

injunctions resulting in limitation or suspension of operations.

There is inherent risk of incurring significant environmental costs and liabilities in exploration and production operations due to generation, handling, and disposal of materials, including wastes and petroleum hydrocarbons. The Registrant may incur joint and several, strict liability under applicable U.S. federal and state environmental laws in connection with releases of petroleum hydrocarbons and wastes on, under or from leased or owned properties, some of which have been used for oil and natural gas exploration and production activities for a number of years, often by third parties not under the Registrant’s control. While the Registrant maintains insurance against some, but not all, of the risks described above, the Registrant’s insurance may not be adequate to cover casualty losses or liabilities. Also, in the future the Registrant may not be able to obtain insurance at premium levels that justify its purchase.

In addition, in response to studies suggesting that emissions of certain gases may be contributing to warming of the earth’s atmosphere, many states are beginning to consider initiatives to track and record these gases, generally referred to as “greenhouse gases,” with several states having already adopted regulatory initiatives aimed at reducing emissions of greenhouse gases. Methane, a primary component of natural gas, and carbon dioxide, a byproduct of the burning of natural gas, are included among the types of gases targeted by greenhouse gas initiatives and laws This movement is in its infancy but regulatory initiatives or legislation placing restrictions on emissions of methane or carbon dioxide that may be imposed in various states of the United States could adversely affect operations of oil and gas wells and the demand for oil and gas products.

ITEM 1B.

Unresolved Staff Comments

None.

ITEM 2.

Properties

Property Interests

The Registrant’s properties consist primarily of interests in properties on which oil and gas wells 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 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, 2013, the Registrant owned working interests in forty-two producing wells. The Registrant had no drilling activity for the years ended December 31, 2013 and 2012.

Third Party Review of Reserves Estimate

The reserves estimate shown herein has been independently evaluated by Forrest A. Garb & Associates, Inc. Their reserves estimate is filed with this report as Exhibit 99.1. The qualifications of William Donald Harris III, P.E., the technical person primarily responsible for overseeing his firm’s preparation of the Partnership’s reserve estimates are set forth below.

Over 25 years of practical experience in petroleum engineering
Registered professional engineer in the state of Texas
Bachelor of Science Degree in Petroleum Engineering
Master of Business Administration

Internal Controls Over Reserves Estimate

MD, the Registrant’s managing general partner, maintains internal controls such as the following to ensure the reliability of reserves estimation:

No employee’s compensation is tied to the amount of reserves booked.
Comprehensive SEC-compliant internal policies are followed to determine and report proved reserves.
Reserves estimate is made by experienced reservoir engineers or under their direct supervision.
The reservoir engineers review all the Partnership’s reported proved reserves at the close of each quarter.

ITEM 3.

Legal Proceedings

From time to time, the Registrant may be a party to certain legal actions and claims arising in the ordinary course of business. While the outcome of these events cannot be predicted with certainty, the Partnership does not expect these matters to have a material effect on its financial position or results of operations.

ITEM 7.

Management’s Discussion and Analysis of Financial Condition and Results of Operations

General

The Registrant was organized as a Delaware limited partnership on February 27, 2002. The offering of limited and general partnership interests began June 26, 2002 as a part of an offering registered under the name Mewbourne Energy Partners 02-03 Drilling Programs. The offering of limited and general partner interests in the Registrant concluded October 10, 2002, with total investor partner contributions of $16,072,000.

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 is a comparative discussion of the results of operations for the periods indicated. It should be read in conjunction with the financial statements and the related notes to the financial statements, which begin on page 20.

Year ended December 31, 2013 compared to the year ended December 31, 2012:

	Year Ended December 31,
	2013		2012
Oil sales	$	122,145	$	148,600
Barrels produced		1,332		1,667
Average price/bbl	$	91.70	$	89.14

Gas sales	$	645,400	$	590,786
Mcf produced		171,964		203,987
Average price/mcf	$	3.75	$	2.90

Oil and gas revenues. As shown in the above table, total oil and gas sales rose by $28,159, a 3.8% increase, for the year ended December 31, 2013 as compared to year ended December 31, 2012.

Of this increase, $4,265 and $174,800 were due to increases in the average prices of oil and gas sold, respectively. The average prices rose to $91.70 from $89.14 per barrel (bbl) and to $3.75 from $2.90 per thousand cubic feet (mcf) for the year ended December 31, 2013 as compared to the year ended December 31, 2012.

These increases were partially offset by decreases of $30,720 and $120,186 due to decreases in the volumes of oil and gas sold, respectively. Volumes fell by 335 bbls and 32,023 mcf for the year ended December 31, 2013 as compared to the year ended December 31, 2012.

Lease operations. Lease operating expense during the year ended December 31, 2013 increased to $419,306 from $405,199 for the year ended December 31, 2012 due to more well repairs and workovers.

Production taxes. Production taxes during the year ended December 31, 2013 rose to $47,616 from $43,845 during the year ended December 31, 2012 due to higher overall oil and gas revenue.

Depreciation, depletion and amortization. Depreciation, depletion and amortization fell to $133,982 for the year ended December 31, 2013 from $153,936 for the year ended December 31, 2012 due to lower oil and gas production.

Liquidity and Capital Resources

Cash increased by $189 during the year ended December 31, 2013. Cash flows from operating activities were utilized primarily for cash distributions to partners. All wells for which funds have been committed have been drilled. Any incidental future capital expenditures incurred will be paid with current available cash and revenues generated through oil and gas sales. Revenues which, in the sole judgment 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.

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 and future abandonment costs. Changes in oil and gas prices and the changes in production estimates could have a significant effect on reserve estimates. The reserve estimates directly impact the computation of depreciation, depletion, and amortization, asset retirement obligation, and the ceiling test for the Registrant’s oil and gas 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. Additionally, the Registrant has no contractual obligations but has a financial obligation to plug and abandon non-producing properties as discussed below.

Full Cost Method of Accounting

The Registrant follows the full-cost method of accounting for its oil and gas activities. Under the full-cost method, all productive and non-productive 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 a quarterly 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. The present value of future net cash flows has been prepared by using the oil and gas pricing guidelines established by the Securities and Exchange Commission, projected development and production costs and a 10 percent annual discount rate.

Asset Retirement Obligations

The Partnership has recognized an estimated liability for future plugging and abandonment costs. A liability for the estimated fair value of the future plugging and abandonment costs is recorded with a corresponding increase in the full cost pool at the time a new well is drilled. Depreciation expense associated with estimated plugging and abandonment costs is recognized in accordance with the full cost methodology.

The Partnership estimates a liability for plugging and abandonment costs based on historical experience and estimated well life. The liability is discounted using the credit-adjusted risk-free rate. Revisions to the liability could occur due to changes in well plugging and abandonment costs or well useful lives, or if federal or state regulators enact new well restoration requirements. The Partnership recognizes accretion expense in connection with the discounted liability over the remaining life of the well.

A reconciliation of the Partnership’s liability for well plugging and abandonment costs for the years ended December 31, 2013 and December 31, 2012 is as follows:

		2013			2012

Balance, beginning of period	$	534,496		$	513,376
Liabilities incurred		3,954			—
Liabilities reduced due to plugging and abandonments		(3,048	)		—
Accretion expense		21,992			21,120
Balance, end of period	$	557,394		$	534,496

Organization and Related Party Transactions

The Partnership was organized on February 27, 2002 in accordance with the laws of the state of Delaware. MD, a Delaware Corporation, has been appointed as the Registrant’s managing general partner. MD has no significant equity interest in the Registrant. 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.

In the ordinary course of business, MOC will incur certain costs that will be passed on to well owners of the well for which the costs were incurred. The Partnership will receive their portion of these costs based upon their ownership in each well incurring the costs. These costs are referred to as operator charges and are standard and customary in the oil and gas industry. Operator charges include recovery of gas marketing costs, fixed rate overhead, supervision, pumping, and equipment furnished by the operator, some of which will be included in the full cost pool pursuant to Rule 4-10(c)(2) of Regulation S-X. Amounts accrued for and paid to MOC for operator charges totaled $250,326 and $219,643 for the years ended December 31, 2013 and 2012, respectively. Operator charges are billed in accordance with the Program and Partnership Agreements.

In accordance with the Partnership agreement, during any particular calendar year, the total amount of administrative expenses allocated to the Partnership by MOC 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. Administrative expenses can only be paid out of funds available for distributions. Under this arrangement, $27,680 and $27,427 were allocated to the Partnership during the years ended December 31, 2013 and 2012, respectively.

The Partnership participates in oil and gas activities through a Drilling Program Agreement (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%

(1)

As noted above, pursuant to the Program, MD must contribute 100% of organization and offering costs and lease acquisition costs which should approximate 30% of total capital costs. To the extent that organization and offering costs and lease acquisition costs are less than 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.

ITEM 9A.

Controls and Procedures

(a) Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this report, MD’s management conducted an evaluation, under the supervision and with the participation of MD’s principal executive officer and principal financial officer, of the Registrant’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). Based on this evaluation, MD's principal executive officer and principal financial officer concluded that, as of the end of the period covered by this report, the Registrant’s disclosure controls and procedures are effective. Notwithstanding the foregoing, a control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that it will detect or uncover failures within the Registrant to disclose material information otherwise required to be set forth in the Registrant’s periodic reports.

(b) MD Management’s Annual Report on Internal Control Over Financial Reporting

MD’s management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f). Under the supervision and with the participation of MD’s management, including MD’s principal executive officer and principal financial officer, MD conducted an evaluation of the effectiveness of the Partnership’s internal control over financial reporting based on the framework in “Internal Control — Integrated Framework” (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on MD’s evaluation under the framework in “Internal Control — Integrated Framework”, MD’s management concluded that internal control over financial reporting was effective as of December 31, 2013. This annual report does not include an attestation report of the Registrant’s independent registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by the Registrant’s independent registered public accounting firm pursuant to rules of the Securities and Exchange Commission that permit the Registrant to provide only management’s report in this annual report. There have been no changes in MD’s internal controls for the quarter ended December 31, 2013 or in other factors which have materially affected, or are reasonably likely to materially affect the internal controls over financial reporting.

FINANCIAL STATEMENTS

WITH REPORT OF INDEPENDENT REGISTERED ACCOUNTING FIRM

As of and for the years ended December 31, 2013 and 2012

Report of Independent Registered Public Accounting Firm

To the Partners of Mewbourne Energy Partners 02-A, L.P. and to the Board of Directors of Mewbourne Development Corporation

Tyler, Texas

We have audited the accompanying balance sheets of Mewbourne Energy Partners 02-A, L.P. (Partnership) as of December 31, 2013 and 2012 and the related statements of operations, changes in partners’ capital and cash flows for the years then ended. These financial statements are the responsibility of the Partnership’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits 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. The Partnership is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Partnership’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also 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, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Partnership at December 31, 2013 and 2012, and the results of its operations and its cash flows for the years then ended in conformity with accounting principles generally accepted in the United States of America.

NOTES TO FINANCIAL STATEMENTS

1. Description of Business

Mewbourne Energy Partners 02-A, L.P., (the “Registrant” or the “Partnership”), a Delaware limited partnership engaged primarily in oil and gas development and production in Texas, Oklahoma, and New Mexico, was organized on February 27, 2002. The offering of limited and general partnership interests began June 26, 2002 as a part of an offering registered under the name Mewbourne Energy Partners 02-03 Drilling Programs, (the “Program”), and concluded October 10, 2002, with total investor contributions of $16,072,000 originally being sold to 647 subscribers of which $14,667,000 were sold to 597 subscribers as general partner equity interests and $1,405,000 were sold to 50 subscribers as limited partner equity interests. During 2004 all general partner equity interests were converted to limited partner equity interests. The managing general partner has no significant equity interest in the Partnership.

The Program’s sole business is the development and production of oil and gas. A substantial portion of the Program’s gas production is being sold regionally in the spot market. Due to the highly competitive nature of the spot market, prices are subject to 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.

2. Summary of Significant Accounting Policies

Full Cost Accounting

The Partnership follows the full-cost method of accounting for its oil and gas activities. Under the full-cost method, all productive and non-productive 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. At December 31, 2013 and 2012, all capitalized costs were subject to amortization. Proceeds from the sale or other disposition of properties are credited to the full cost pool. Gains and losses 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 a quarterly 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. There were no cost ceiling write-downs during the years ended December 31, 2013 and 2012.

Cash

The Partnership maintains all its cash in one financial institution. At various times throughout the year, the cash amount may be in excess of the amount insured by the Federal Deposit Insurance Corporation.

Fair Value of Financial Instruments

The Financial Accounting Standards Board (“FASB”) has issued guidance on determining the estimated fair value for financial instruments. This disclosure states that the fair value of financial instruments is determined at discrete points in time based on relevant market information. Such estimates involve uncertainties and cannot be determined with precision. The estimated fair value of cash, accounts receivable and accounts payable approximates their carrying value due to their short-term nature.

Asset Retirement Obligations

A reconciliation of the Partnership’s liability for well plugging and abandonment costs for the years ended December 31, 2013 and December 31, 2012 is as follows:

		2013			2012
Balance, beginning of period	$	534,496		$	513,376
Liabilities incurred		3,954			—
Liabilities reduced due to settlements		(3,048	)		—
Accretion expense		21,992			21,120
Balance, end of period	$	557,394		$	534,496

Oil and Gas Sales

The Program’s oil and condensate production is sold 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 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, 2013 and 2012, no material gas imbalances between the Partnership and other working interest owners existed.

Substantially all of the Partnership’s accounts receivable result from oil and natural gas sales to third parties in the oil and natural gas industry. This concentration of customers may impact the Partnership’s overall credit risk in that these entities may be similarly affected by changes in economic and other conditions. Historically, the Partnership has not experienced significant credit losses on such receivables. No bad debt expense was recorded in 2013 or 2012. The Partnership cannot ensure that such losses will not be realized in the future.

Comprehensive Income

Comprehensive income is defined as a change in equity of a business enterprise during a period from transactions and other events and circumstances from non-partner sources and includes all changes in equity during a period except those resulting from investments by partners and distributions to partners. The Partnership has no items of comprehensive income, other than net income, in any period presented. Therefore, net income as presented in the statements of operations equals comprehensive income.

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. The Partnership’s financial reporting basis of its net assets exceeded the tax basis of its net assets by $2,250,143 and $2,368,357 at December 31, 2013 and 2012, respectively.

The Partnership accounts for uncertainty in income taxes in accordance with applicable accounting guidance and recognizes the effects of those positions only if they are more likely than not of being sustained. As no liability had been recognized as of December 31, 2013 or 2012, the Partnership did not accrue for any interest or penalties.

3. Organization and Related Party Transactions:

The Partnership was organized on February 27, 2002 in accordance with the laws of the state of Delaware. MD, a Delaware Corporation, has been appointed as the Registrant’s managing general partner. MD has no significant equity interest in the Registrant. 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.

In the ordinary course of business, MOC will incur certain costs that will be passed on to well owners of the well on which the costs were incurred. The Partnership will be charged their portion of these costs based upon their ownership in each well incurring the costs. These costs are referred to as Operator charges and are standard and customary in the oil and gas industry. Operator charges include recovery of gas marketing costs, fixed rate overhead, supervision, pumping, and equipment furnished by the operator, some of which will be included in the full cost pool pursuant to Rule 4-10(c)(2) of Regulation S-X. Amounts accrued for and paid to MOC for operator charges totaled $250,326 and $219,643 for the years ended December 31, 2013 and 2012, respectively. Operator charges are billed in accordance with the Program and Partnership Agreements.

Costs incurred in oil and natural gas acquisition, exploration and development activities for the years ended December 31, 2013 and 2012 were:

		2013				2012
Development		$	320			$	40,504

Capitalized costs related to oil and natural gas acquisition, exploration and development activities for the years ended December 31, 2013 and 2012 were as follows:

		2013			2012
Cost of oil and natural gas properties at year-end:
Producing assets - Proved properties	$	16,950,665		$	16,950,345

Total capitalized cost		17,305,066			17,302,828
Accumulated depreciation, depletion,
amortization and impairment		(15,016,631	)		(14,881,637	)
Net capitalized costs	$	2,288,435		$	2,421,191

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, Forrest A. Garb & Associates Inc., in accordance with guidelines established by the Securities and Exchange Commission and the FASB’s accounting standard. The Partnership considers reserve estimates to be reasonable; however, due to inherent uncertainties and the limited nature of reservoir data, estimates of oil and gas reserves are imprecise and subject to change over time as additional information becomes available.

These reserve estimates have been prepared using projected costs and the average first-of-the-month natural gas and oil prices for the twelve months ended December 31, 2013 and the twelve months ended December 31, 2012.

There have been no favorable or adverse events that have caused a significant change in estimated proved reserves since December 31, 2013. 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. All proved reserves are developed; therefore, the Partnership has no proved undeveloped properties for the years ended December 31, 2013 and 2012.

	Crude Oil and
	Condensate			Natural Gas

(1) All of these reserves are categorized as proved developed.

Technologies Used in Reserves Estimation

Proved reserves are those quantities of oil and natural gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations. The term “reasonable certainty” implies a high degree of confidence that the quantities of oil technologies that an entity can use to establish reserves. The SEC now allows use of techniques that have been proved effective by actual production from projects in the same reservoir or an analogous reservoir or by other evidence using reliable technology that establishes reasonable certainty. Reliable technology is a grouping of one or more technologies (including computational methods) that have been field tested and has been demonstrated to provide reasonably certain results with consistency and repeatability in the formation being evaluated or in an analogous formation. To achieve reasonable certainty, our technical team employs technologies that have been demonstrated to yield results with consistency and repeatability. The technologies and economic data used in the estimation of our proved reserves may include, but are not limited to, empirical evidence through drilling results and well performance, well logs, geologic maps and available downhole and production data, seismic data, well test data and reservoir simulation modeling.
