PART I



|ITEM 1. | Business
|------- | --------

Mewbourne Energy Partners 06-A, L.P. (the
Registrant or the Partnership) is a limited partnership organized under the laws of the State of Delaware on November 16, 2005 (date of inception). In accordance with the laws of the state of Delaware, Mewbourne
Development Corporation (MD), a Delaware Corporation, has been appointed as the Registrants managing general partner. MD has no 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 06-07 Drilling Programs. General and limited partnership interests were offered at $1,000 each. The maximum offering amount was $50,000,000 (50,000 interests) per partnership. The Registrant was declared effective by the Securities and
Exchange Commission on July 11, 2006. On September 1, 2006, the offering of limited and general partnership interests in the Registrant was closed, with interests aggregating $50,000,000 originally being sold to 1,576 subscribers of which
$43,174,000 were sold to 1,342 subscribers as general partner interests and $6,826,000 were sold to 234 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 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.

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.

##### Table of Contents

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 30, 2007, MOC employed 161 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 and capacity of natural gas pipelines and other transportation facilities;
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | 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. Further, oil and natural gas prices
do not necessarily move in tandem. Because approximately 85% of the Registrants reserves at December 31, 2006 were natural gas reserves, the Registrant is more affected by movements in natural gas prices.

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



4



---

##### Table of Contents

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 prices for oil and natural gas at that date. A significant decline in oil and natural gas prices from current
levels, or other factors, without other mitigating circumstances, could cause a future writedown of capitalized costs and a non-cash charge against future earnings.

The Registrants ceiling test calculations for the year ended December 31, 2006 indicated an impairment of oil and natural gas properties of approximately $3.8 million.

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. Our drilling operations involve risks from high pressures and from mechanical difficulties such as stuck pipes, collapsed casings and
separated cables. 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 and the demand for oil and gas products.

None.



|ITEM 2. | Properties
|------- | ----------

The Registrants properties consist primarily of
interests in properties on which oil and gas wells are located both producing and in progress. 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, 2006, 17 wells had been drilled and were productive. The following table
summarizes the Registrants drilling activity for the year ended December 31, 2006:



|                  |  |       |  |            |  |      |  |

|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 November 16, 2005. The offering of limited
and general partnership interests began July 11, 2006 as a part of an offering registered under the name Mewbourne Energy Partners 06-07 Drilling Programs. The offering of limited and general partner interests in the Registrant concluded
September 1, 2006, with total investor partner contributions of $50,000,000.

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

Because the Registrant was formed during the period covered by this report, no trend analysis based on yearly changes in liquidity, capital resources or results of operations is available.

Revenues and other income for the year ended December 31, 2006 totaled $1,093,393, and consisted of oil and gas sales in the amount of $401,814, and interest income
in the amount of $691,579. Gas production volume during the year ended December 31, 2006 amounted to approximately 51,558 Mcf of gas at a corresponding average realized price of $6.72 per Mcf of gas. Oil production volume during the year ended
December 31, 2006 amounted to approximately 951 Bbls of oil at a corresponding average realized price of $58.28 per Bbl of oil. Expenses totaling $4,064,949, consisted primarily of depreciation, depletion and amortization and cost ceiling write
down in the amount of $234,083 and $3,782,238 respectively. Lease operating expenses totaled $14,980. Production taxes were $29,077. Administrative and general expenses were $4,328. Asset retirement obligation accretion expenses were $243. While the
Partnership was organized on November 16, 2005 no activity began until the 2006. At December 31, 2006, 17 wells had been drilled and were productive. The Registrants oil and gas revenues should increase during 2007 as additional
wells are completed and oil and gas production is sold. Interest income should decrease in 2007 as the remaining wells are drilled and the available cash is utilized for equipping of such wells. The Registrant expects that drilling and completion
costs will decrease during 2007 and that lease operating cost and depletion provisions will increase.

Liquidity and capital resources

Cash and cash equivalents were $20,312,671 at December 31, 2006. Approximately $25,971,489 of the initial partners capital of $50,000,000 was used for drilling
and completion and prepaid well costs and $4,250,000 was utilized for sale commissions and due diligence fees. Capital requirements in the future are expected to be paid with remaining cash on hand. Management believes that funds are sufficient to
complete the wells for which funds have been committed. Management expects these wells to be drilled in 2007. Under certain circumstances, as provided in the Registrants Partnership Agreement, the Registrant may use revenues and/or borrow
monies, either through a financial institution or through an affiliate of MD, to fund additional capital requirements. 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, 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, asset retirement obligation, and the ceiling test for the Registrants oil and gas properties.

##### Table of Contents

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 assuming year-end selling prices, year-end development and production costs and a 10 percent annual discount
rate.

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.

Asset Retirement Obligations

In accordance with FAS 143, the Partnership has recognized an estimated liability for future
plugging and abandonment costs. The estimated liability is 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 year ended December 31, 2006, is as
follows:

Organization and Related Party Transactions

The Partnership was organized on November 16, 2005. 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 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 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. Reimbursement to MOC for operator charges totaled $473,065 for the year ended December 31, 2006. Operator charges are billed in
accordance with the program and partnership agreements.

In consideration for services rendered by MD in managing the business of the Partnership, the
Partnership during each of the initial three years of the Partnership will pay to MD

a management fee in the amount equal to 7/10s of 1% of the subscriptions by the investor partners to the Partnership. Management fees can only be paid
out of funds available for distributions. Since there were not sufficient funds available for distribution management fees were not allocated to the Partnership for the year ended December 31, 2006.

In general, 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. Since there were not sufficient funds available for distribution administrative expenses were not allocated to
the Partnership for the year ended December 31, 2006.

The Partnership participates in oil and gas activities through a Drilling Program Agreement
(the Program). The Partnership and MD are parties to the Program. The costs and revenues of the Program are allocated to MD and the Partnership as follows:

|(1) | Pursuant to the Program, MD must contribute 100% of organization and offering costs and lease acquisition costs which approximate 20% of total capital costs. To the extent that
organization and offering costs and lease acquisition costs are less than 20% of total capital costs, MD is responsible for tangible drilling costs until its share of the Programs total capital costs reaches approximately 20%.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The Partnerships financial statements reflect its respective proportionate interest in the Program.



|ITEM 7A. | Quantitative and Qualitative Disclosures about Market Risk
|-------- | ----------------------------------------------------------

1.
Interest Rate Risk

The Partnership Agreement allows borrowings from banks or other financial sources of up to 20% of the total capital contributions to the
Partnership without investor approval. Should the Partnership elect to borrow monies for additional development activity on Partnership properties, it will be subject to the interest rate risk inherent in borrowing activities. Changes in interest
rates could significantly affect the Partnerships results of operations and the amount of net cash flow available for partner distributions. Also, to the extent that changes in interest rates affect general economic conditions, the Partnership
will be affected by such changes.

##### Table of Contents

2. Commodity Price Risk

The
Partnership does not expect to engage in commodity futures trading or hedging activities or enter into derivative financial instrument transactions for trading or other speculative purposes. The Partnership currently expects to sell a vast
majority of its production from successful oil and gas wells on a month-to-month basis at market prices. Accordingly, the Partnership is at risk for the volatility in commodity prices inherent in the oil and gas industry, and the level of commodity
prices will have a significant impact on the Partnerships results of operations. For the year ended December 31, 2006, a 10% change in the price received for natural gas production would have had an approximate $35,000 impact on our
revenue.

3. Exchange Rate Risk

The Partnership currently has
no income from foreign sources or operations in foreign countries that would subject it to currency exchange rate risk. The Partnership does not currently expect to purchase any prospects located outside of either the United States or United States
coastal waters in the Gulf of Mexico.



|ITEM 8. | Financial Statements and Supplementary Data
|------- | -------------------------------------------

The required financial
statements of the Registrant are contained in a separate section of this report following the signature attestation. See Item 15. Exhibits, Financial Statement Schedules and Reports on Form 8-K.



|ITEM 9. | Changes in and Disagreements with Accountants on Accounting and Financial Disclosure
|------- | ------------------------------------------------------------------------------------

None.



|ITEM 9A. | Controls and Procedures
|-------- | -----------------------

MD maintains a system of controls and
procedures designed to provide reasonable assurance as to the reliability of the financial statements and other disclosures included in this report, as well as to safeguard assets from unauthorized use or disposition. MDs Chief Executive
Officer and Chief Financial Officer have evaluated the effectiveness of the design and operation of its disclosure controls and procedures with the assistance and participation of other members of management. Based upon that evaluation, MDs
Chief Executive Officer and Chief Financial Officer concluded that as of December 31, 2006 its disclosure controls and procedures are effective for gathering, analyzing and disclosing the information the Partnership is required to disclose in
the reports it files under the Securities Exchange Act of 1934 within the time periods specified in the SECs rules and forms. There have been no changes in MDs internal controls for the quarter ended December 31, 2006 or in other
factors which have materially affected, or is reasonable likely to materially affect the internal controls over financial reporting.

##### Table of Contents

Report of Independent Registered Public Accounting Firm

To the Partners of Mewbourne Energy Partners 06-A, L.P. and to the Board of Directors of Mewbourne Development Corporation:

We have audited the accompanying balance sheet of Mewbourne Energy Partners 06-A, L.P. as of December 31, 2006 and the related statement of operations, changes in
partners capital, and cash flows for the year 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 audit.

We conducted our audit in accordance with the standards of the Public Partnership 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 audit provides 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 Mewbourne Energy Partners 06-A, L.P. at
December 31, 2006, and the results of its operations and its cash flows for the year then ended, in conformity with accounting principles generally accepted in the United States of America.

NOTES TO FINANCIAL STATEMENTS



|1. | Significant Accounting Policies:
|-- | --------------------------------

Accounting for Oil and
Gas Producing Activities

Mewbourne Energy Partners 06-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 November 16, 2005. The offering of limited and general partnership interests began July 11, 2006 as a part of an offering
registered under the name Mewbourne Energy Partners 06-07 Drilling Programs, (the Program), and concluded September 1, 2006, with total investor contributions of $50,000,000 originally being sold to 1,576 subscribers of which
$43,174,000 were sold to 1,342 subscribers as general partner equity interests and $6,826,000 were sold to 234 subscribers as limited partner equity interests. The managing general partner has no equity interest in the partnership.

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 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 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, 2006, approximately $5.31 million of capitalized costs were excluded from 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 was a cost ceiling write-down of $3,782,238 for the year ended December 31, 2006. Prepaid
well costs represent payments to Mewbourne Oil Company, a related party, for the acquisition, exploration and development of oil and gas properties for which the Partnership is contractually obligated but activities have not yet commenced.

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, 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, asset retirement obligation, and the ceiling test for the Registrants oil and gas properties.

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.

##### Table of Contents

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. At various times throughout the year, the cash amount may be in excess of the amount insured by the Federal Deposit Insurance Corporation.

Asset Retirement Obligations

In accordance with FAS 143, the Partnership has recognized an estimated liability for future
plugging and abandonment costs. The estimated liability is 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 year ended December 31, 2006, is as
follows:



|                             |  |      |

|                             |  |      |       

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, 2006, 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.



|2. | Organization and Related Party Transactions:
|-- | --------------------------------------------

The Partnership was
organized on November 16, 2005. 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 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.

##### Table of Contents

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. Reimbursement to MOC for operator charges totaled $473,065 for the year ended
December 31, 2006. Operator charges are billed in accordance with the program and partnership agreements.

In consideration for services rendered by
MD in managing the business of the Partnership, the Partnership during each of the initial three years of the Partnership will pay to MD a management fee in the amount equal to 7/10s of 1% of the subscriptions by the investor partners to the
Partnership. Management fees can only be paid out of funds available for distributions. Since there were not sufficient funds available for distribution management fees were not allocated to the Partnership for the year ended December 31, 2006.

In general, 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. Since there were not sufficient funds available for distribution administrative expenses were not
allocated to the Partnership for the year ended December 31, 2006.

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:

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 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 oil and gas 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, 2006. 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.
