Accounting for Oil and Gas Producing Activities

Mewbourne Energy Partners 04-A, L.P., (the Registrant or the Partnership), a
Delaware limited partnership is engaged primarily in oil and gas development and production in Texas, Oklahoma, and New Mexico, and was organized on January 27, 2004. The offering of limited and general partnership interests began June 10,
2004 as a part of an offering registered under the name Mewbourne Energy Partners 04-05 Drilling Programs, (the Program), and concluded August 20, 2004, with total investor contributions of $30,000,000 originally being sold to 1,118
subscribers of which $27,235,000 were sold to 1,022 subscribers as general partner interests and $2,765,000 were sold to 96 subscribers as limited partner interests.

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 March 31, 2006, all capitalized costs were subject to amortization, while at March 31, 2005, approximately $4.1 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 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 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.

3. Asset Retirement Obligations

In accordance with Financial Accounting Standards Board Statement No. 143, Accounting for Asset Retirement Obligations, 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 three months ended March 31, 2006, is as follows:



|                             |  |   |        
|---------------------------- |  | - | -------
|Balance, beginning of period |  | $ | 377,536
|Accretion expense            |  |   | 3,406  
|                             |  |   |        
|Balance, end of period       |  | $ | 380,942
|                             |  |   |        

4. Related Party Transactions

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.

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. Services and 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. Effective 01/01/2006 the Partnership has elected to include the
management fee as part of the full cost pool pursuant to Rule 4-10(c)(6)(iii) and (iv) of Regulation S-X. The Partnership analyzed prior periods and determined that this change would not have been material in prior statements.

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.

for their respective interests.

|(2) | As noted above, 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%.

Item 2. Managements Discussion and Analysis of Financial Condition and Results of Operations

Liquidity and Capital Resources

Mewbourne Energy Partners 04-A, L.P. was formed January 27, 2004. The offering of limited and general
partnership interests began June 10, 2004 and concluded August 20, 2004, with total investor contributions of $30,000,000.

The Partnership has
acquired interests in oil and gas prospects for the purpose of development drilling. The Partnership participated in the drilling of 78 wells. 73 wells were productive and 5 wells were abandoned.

Future capital requirements and operations will be conducted with available funds generated from oil and gas activities. No bank borrowing is anticipated. The
Partnership had net working capital of $1,909,835 at March 31, 2006.

During the three months ended March 31, 2006, the Partnership made cash
distributions to the investor partners in the amount of $5,059,998 as compared to $885,000 for the three months ended March 31, 2005. The Partnership expects that cash distributions will continue during 2006 as additional oil and gas revenues
are sufficient to produce cash flows from operations.

The sale of crude oil and natural gas produced by the Partnership will be affected by a number of
factors that are beyond the Partnership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 Partnership.

As shown in the table above, total oil and gas sales increased $1,444,791 (64.5%) for the three months ended
March 31, 2006 as compared to the three months ended March 31, 2005. Of this increase, $60,384 and $835,652, respectively, were related to increases in volumes of oil and gas sold. Volumes of oil and gas sold increased 997 bbls of oil and
116,172 mcf of gas for the three months ended March 31, 2006 as compared to the three months ended March 31, 2005. The increase in volumes of oil and gas sold was primarily due to the addition of 37 new wells completed since March 31,
2005. The increase in oil and gas sales was also attributable to increases of $23,053 and $525,702, respectively, related to increases in the average prices of oil and gas sold. Average oil and gas prices increased to $60.54 per bbl and $7.19 per
mcf for the three months ended March 31, 2006 from $49.39 per bbl and $5.77 per mcf for the three months ended March 31, 2005.

Interest income.
Interest income was $6,456 during the three months ended March 31, 2006 as compared to $46,272 during the three month period ended March 31, 2005. The decrease is primarily due to the decrease in funds available for investment.

Lease operations and production taxes. Lease operating expense during the period ended March 31, 2006 totaled $106,139 as compared to $68,029 for the period
ended March 31, 2005. Production taxes during the period ended March 31, 2006 totaled $301,250 as compared to $179,576 for the period ended March 31, 2005. Lease operating expense increased primarily due to the addition of 39 new
wells from the period March 31, 2005 through March 31, 2006. The increase in production taxes is due to the increase in oil and gas revenues.

Depreciation, depletion and amortization. Depreciation, depletion and amortization for the three month period ended March 31, 2006 total $1,122,013 compared to $791,909 for the three month period ended March 31, 2005. The increase
is due to the increase in production volumes.

Administrative and general expense. Administrative and general expense for the three month period ended
March 31, 2006 total $256,183 compared to $80,679 for the period ended March 31, 2005. The overall increase is due to increased administrative charges caused by increased oil and gas revenues. The increase was also related to higher
general expenses for reporting costs.
