Notes to Financial Statements

1. Organization

Southwest Oil & Gas Income Fund VIII-A, L.P. was organized under the laws of the state of Delaware on November 30, 1987, for the purpose of acquiring producing oil and gas properties and to produce and market crude oil and natural gas produced from such properties for a term of 50 years, unless terminated at an earlier date as provided for in the Partnership Agreement. The Partnership sells its oil and gas production to a variety of purchasers with the prices it receives being dependent upon the oil and gas economy. Southwest Royalties, Inc., a wholly owned subsidiary of Clayton Williams Energy, Inc., serves as the Managing General Partner.

Revenues, costs and expenses are allocated as follows:

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

(1)

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

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

2. Summary of Significant Accounting Policies

The interim financial information as of ~~September~~March 3031, ~~2009~~2010, and for the three ~~and nine~~ months ended ~~September~~March 3031, ~~2009~~2010, is unaudited. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted in this Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission. However, in the opinion of management, these interim financial statements include all the necessary adjustments to fairly present the results of the interim periods and all such adjustments are of a normal recurring nature. The interim consolidated financial statements should be read in conjunction with the Partnership’s Annual Report on Form 10-K for the year ended December 31, ~~2008~~2009.

3. Abandonment Obligations

The Partnership follows the provisions of ASC topic 410-20, formerly SFAS No. 143, “Accounting for Asset Retirement Obligations” (“SFAS 143”). ASC topic 410-20 requires the Partnership to recognize a liability for the present value of all legal obligations associated with the retirement of tangible, long-lived assets and capitalize an equal amount as a cost of the asset. The cost associated with the abandonment obligations, along with any estimated salvage value, is included in the computation of depreciation, depletion and amortization.

Changes in abandonment obligations for the nine months ended September 30, 2009 and 2008 are as follows:

	2009			2008
Beginning of period	$	574,148		$	664,205

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

General

Southwest Oil & Gas Income Fund VIII-A, L.P. was organized as a Delaware limited partnership on November 30, 1987. The offering of such limited partnership interests began on March 31, 1988~~. Minimum~~, minimum capital requirements were met on July 6, 1988, and the offering concluded on March 31, 1989, with total limited partner contributions of $6,798,000.

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

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

Production costs and general and administrative costs usually decrease with production declines; however, these costs may not decrease proportionately to production volumes or revenues. Net income available for distribution to the partners is therefore expected to decline in later years based on these factors.

The Partnership recognizes income from oil and gas properties on an accrual basis while the quarterly cash distributions are based on a calculation of actual cash received from oil and gas sales, net of expenses incurred during that quarterly period. If the calculation results in expenses incurred exceeding the oil and gas income received during a quarter, no cash distribution is due until the deficit is recovered from future cash flows.

Oil and Gas Properties

The Partnership uses the full cost method of accounting for its oil and gas producing activities. Accordingly, all costs associated with acquisition, exploration, and development of oil and gas reserves are capitalized. Depletion is provided using the unit-of production method based upon estimates of proved oil and gas reserves. The amortizable base includes estimated future development costs and dismantlement, restoration and abandonment costs, net of estimated salvage value. All of the Partnership’s oil and gas properties are located within the United States. Gain or loss on the sale of oil and gas properties is not recognized unless significant oil and gas reserves are sold.

Should the net capitalized costs exceed the estimated present value of oil and gas reserves, discounted at 10%, such excess costs would be charged to current expense. As of ~~September~~March 3031, ~~2009~~2010, the net capitalized costs did not exceed the estimated present value of oil and gas reserves.

Critical Accounting Policies

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

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

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

~~Oil~~While ~~and gas~~the quantities of proved reserves require substantial judgment, the associated prices ~~have~~of aoil ~~significant~~and ~~impact~~natural ongas reserves that are included in the discounted present value of the ~~Partnership’s~~ ~~estimated~~reserves ~~proved~~do ~~oil~~not require judgment. Current SEC financial accounting and ~~gas~~reporting ~~reserves~~standards require that pricing parameters be the arithmetic average of the first-day-of-the-month price for the 12-month period preceding the effective date of the reserve report. The ceiling calculation dictates that those prices ~~and~~be ~~costs~~held inconstant. ~~effect~~Because asthe ofceiling ~~the~~calculation ~~last~~dictates ~~day~~that ofprices ~~the period~~and costs are ~~generally~~ held constant indefinitely~~.

Operating Results

The following discussion compares our results for the nine months ended September 30, 2009 and 2008. Unless otherwise indicated, references to 2009 and 2008 within this section refer to the respective nine-month period.

Revenues

Comparing 2009 to 2008, oil and gas sales decreased $2,090,582, of which price variances accounted for a $1,782,905 decrease and production variances accounted for a $307,677 decrease.

Production in 2009 (on a BOE basis) was 9% lower than 2008. Oil production decreased 7% in 2009. Gas production was 21% lower in 2009 than 2008 due primarily to production declines on three properties.

In 2009, our realized oil price was 53% lower than 2008, while our realized gas price was 64% lower. Historically, the markets for oil and gas have been volatile, and they are likely to continue to be volatile.

Expenses

Oil and gas production costs on a BOE basis decreased from $27.50 per BOE in 2008 to $27.29 per BOE in 2009. The decrease in oil and gas production costs was due primarily to lower productions taxes resulting from lower oil and gas revenues.

Depletion on a BOE basis increased 64% in 2009. Comparing 2009 to 2008, depletion expense increased $8,874, of which rate variances accounted for a $10,579 increase and production variances accounted for a $1,705 decrease.

Accretion expense increased 24% in 2009 due primarily to changes in asset retirement obligations.

General and administrative (“G&A”) expenses were 2% higher in 2009 as compared to 2008.

Texas Margin Taxes

In May 2006, the State of Texas adopted House Bill 3, which modified the state’s franchise tax structure, replacing the previous tax based on capital or earned surplus with a margin tax (the “Texas Margin Tax”) effective with franchise tax reports filed on or after January 1, 2008. The Texas ~~Margin~~margin Tax is computed by applying the applicable tax rate (1% for the Partnership’s business) to the profit margin, which is generally determined by total revenue less either cost of goods sold or compensation as applicable. Although House Bill 3 states that the Texas Margin Tax is not an income tax, the Partnership believes that Statement of Financial Accounting Standards No. 109 “Accounting for Income Taxes” (“SFAS 109”) applies to the Texas Margin Tax. However the Partnership believes, based on its interpretation, that the Texas Margin Tax does not apply to the Partnership because it qualifies under the passive entity exclusion.

Liquidity and Capital Resources

Partnership distributions during the ~~nine~~quarter ~~months~~ending ~~ended~~March ~~September 30~~31, ~~2009~~2010 were $~~370~~325,000, of which $~~333~~292,~~000~~500 was distributed to the limited partners and $3732,~~000~~500 to the general ~~partners~~partner. Cumulative cash distributions of $18,~~054~~589,097 have been made to the general and limited partners as of ~~September~~March 3031, ~~2009~~ 2010. As of ~~September~~March 3031, ~~2009~~2010, $16,~~296~~778,~~929~~429 or $1,~~198~~234.6607 per limited partner unit has been distributed to the limited partners, representing ~~240~~247% of contributed capital.

~~Recent Accounting Pronouncements~~14

Effective July 1, 2009, the Partnership adopted SFAS No. 168, “The Financial Accounting Standards Board (“FASB”) Accounting Standards Codification and the Hierarchy of Generally Accepted Accounting Principles, a replacement of FASB Statement No. 162” (“SFAS 168”) superseded by topic 105-10-5 of the FASB Accounting Standards Codification (“ASC”). SFAS 168 establishes the ASC as the source of authoritative accounting principles recognized by the FASB to be applied by nongovernmental entities in the preparation of financial statements in conformity with GAAP. Other than the manner in which new accounting guidance is referenced, the adoption did not have a material impact on our financial statements.

Effective April 1, 2009, the Partnership adopted SFAS No. 165, “Subsequent Events” (“SFAS 165”) (superseded by ASC topic 855-10-5), which establishes principles and requirements for disclosure of subsequent events. It establishes the period after the balance sheet date during which events or transactions are to be evaluated for potential disclosure. It also establishes the circumstances under which an entity shall recognize events or transactions occurring after the balance sheet date. The adoption of SFAS 165 did not have a material impact on our disclosure of subsequent events.

In December 2008, the SEC released Final Rule, “Modernization of Oil and Gas Reporting”. The new disclosure requirements include provisions that permit the use of new technologies to determine proved reserves if those technologies have been demonstrated empirically to lead to reliable conclusions about reserves volumes. The new requirements also will allow companies to disclose their probable and possible reserves to investors. In addition, the new disclosure requirements require companies to: (1) report the independence and qualifications of its reserves preparer or auditor, (2) file reports when a third party is relied upon to prepare reserves estimates or conducts a reserves audit, and (3) report oil and gas reserves using an average price based upon the prior 12-month period rather than year-end prices. The new disclosure requirements are effective for financial statements for fiscal years ending on or after December 31, 2009. The effect of adopting the SEC rule has not been determined, but it is not expected to have a significant effect on our reported financial position or results of operations.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

The Partnership financial condition, results of operations, and capital resources are highly dependent upon the prevailing market prices of, and demand for, oil and natural gas. These commodity prices are subject to wide fluctuations and market uncertainties due to a variety of factors that are beyond our control. These factors include the level of global demand for petroleum products, foreign supply of oil and gas, the establishment of and compliance with production quotas by oil-exporting countries, trading activities in commodities future markets, weather conditions, the price and availability of alternative fuels, and overall economic conditions, both foreign and domestic. The Partnership cannot predict future oil and gas prices with any degree of certainty. Sustained weakness in oil and gas prices may adversely affect our financial condition, results of operations and cash distributions to partners.

The Partnership is not a party to any derivative or embedded derivative instruments.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

The Managing General Partner has established disclosure controls and procedures that are adequate to provide reasonable assurance that management will be able to collect, process and disclose both financial and non-financial information, on a timely basis, in the Partnership’s reports to the SEC. Disclosure controls and procedures include all processes necessary to ensure that material information is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and is accumulated and communicated to management, including our chief executive and chief financial officers, to allow timely decisions regarding required disclosures.

With respect to these disclosure controls and procedures:

·	management has evaluated the effectiveness of the disclosure controls and procedures as of the end of the period covered by this report;

·	this evaluation was conducted under the supervision and with the participation of management, including the chief executive and chief financial officers of the Managing General Partner; and

it is the conclusion of chief executive and chief financial officers of the Managing General Partner that these disclosure controls and procedures are effective in ensuring that information that is required to be disclosed by the Partnership in reports filed or submitted with the SEC is recorded, processed, summarized and reported within the time periods specified in the rules and forms established by the SEC.

Internal Control Over Financial Reporting

There has not been any change in the Partnership’s internal control over financial reporting that occurred during the ~~nine~~quarter ~~months~~ ended ~~September~~March 3031, ~~2009~~2010 that has materially affected, or is reasonably likely to materially affect, its internal control over financial reporting.

Item 1A. Risk Factors

In evaluating all forward-looking statements, you should specifically consider various factors that may cause actual results to vary from those contained in the forward-looking statements. Our risk factors are included in our Annual Report on Form 10-K for the year ended December 31, ~~2008~~2009, as filed with the U.S. Securities and Exchange Commission on March 2731, ~~2009~~2010 and available at www.sec.gov. ~~Following~~There ~~are~~have ~~additional~~been ~~risk~~no ~~factors~~material ~~that could~~changes ~~affect~~to ~~our~~these ~~financial~~risk ~~performance~~factors orsince ~~could~~the ~~cause~~filing ~~actual~~of ~~results to differ materially from estimates contained in~~ our ~~forward~~Form 10-~~looking statements~~K.

Certain U.S. federal income tax deductions currently available with respect to oil and gas exploration and development may be eliminated as a result of future legislation.

The Proposed Fiscal Year 2010 Budget includes proposed legislation that would, if enacted into law, make significant changes to United States tax laws, including the elimination of certain key U.S. federal income tax incentives currently available to oil and natural gas exploration and production companies. These changes include, but are not limited to: (1) the repeal of the percentage depletion allowance for oil and natural gas properties, (2) the elimination of current deductions for intangible drilling and development costs, (3) the elimination of the deduction for certain domestic production activities, and (4) an extension of the amortization period for certain geological and geophysical expenditures. It is unclear whether any such changes will be enacted or how soon any such changes could become effective. The passage of any legislation as a result of these proposals or any other similar changes in U.S. federal income tax laws could eliminate certain tax deductions that are currently available with respect to oil and gas exploration and development, and any such change could negatively affect our financial condition and results of operations.

The adoption of climate change legislation by Congress could result in increased operating costs and reduced demand for the oil and natural gas we produce.

On June 26, 2009, the U.S. House of Representatives approved adoption of the “American Clean Energy and Security Act of 2009,” also known as the “Waxman-Markey cap-and-trade legislation” or ACESA. The purpose of ACESA is to control and reduce emissions of “greenhouse gases,” or “GHGs,” in the United States. GHGs are certain gases, including carbon dioxide and methane, that may be contributing to warming of the Earth’s atmosphere and other climatic changes. ACESA would establish an economy-wide cap on emissions of GHGs in the United States and would require an overall reduction in GHG emissions of 17% (from 2005 levels) by 2020, and by over 80% by 2050. Under ACESA, most sources of GHG emissions would be required to obtain GHG emission “allowances” corresponding to their annual emissions of GHGs. The number of emission allowances issued each year would decline as necessary to meet ACESA’s overall emission reduction goals. As the number of GHG emission allowances declines each year, the cost or value of allowances is expected to escalate significantly. The net effect of ACESA will be to impose increasing costs on the combustion of carbon-based fuels such as oil, refined petroleum products, and natural gas.

The U.S. Senate has begun work on its own legislation for controlling and reducing emissions of GHGs in the United States. If the Senate adopts GHG legislation that is different from ACESA, the Senate legislation would need to be reconciled with ACESA and both chambers would be required to approve identical legislation before it could become law. President Obama has indicated that he is in support of the adoption of legislation to control and reduce emissions of GHGs through an emission allowance permitting system that results in fewer allowances being issued each year but that allows parties to buy, sell and trade allowances as needed to fulfill their GHG emission obligations. Although it is not possible at this time to predict whether or when the Senate may act on climate change legislation or how any bill approved by the Senate would be reconciled with ACESA, any laws or regulations that may be adopted to restrict or reduce emissions of GHGs would likely require us to incur increased operating costs, and could have an adverse effect on demand for the oil and natural gas we produce.
