 NOTE
1 - DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION
 
 Atlas
Resources Public 17-2007 (A) L.P. (the “Partnership”) is a Delaware Limited
Partnership which includes Atlas Resources, LLC of Pittsburgh, Pennsylvania, as
Managing General Partner ("MGP") and Operator, and 3,226 subscribers to units as
Limited Partners. The Partnership was formed on May 7, 2007 to drill and operate
gas wells located primarily in western Pennsylvania, West Virginia and north
central Tennessee. The Partnership has no employees and relies on its MGP for
management which, in turn, relies on its parent company, Atlas Energy Resources,
LLC, ("Atlas Energy"), for administrative services. On September 29, 2009, Atlas
Energy Resources, LLC and Atlas America, Inc. (“Atlas America”) (NASDAQ: ATLS)
merged with Atlas Energy Resources, LLC becoming a wholly owned subsidiary of
Atlas America. In addition, Atlas America changed its name to “Atlas Energy,
Inc.”
 
 The
financial statements as of September 30, 2009 and for the three months and nine
months ended September 30, 2009 and 2008 are unaudited except that the balance
sheet at December 31, 2008 is derived from audited financial statements. Certain
information and footnote disclosures normally included in financial statements
prepared in accordance with accounting principles generally accepted in the
United States of America (“U.S. GAAP”) have been condensed or omitted in this
Form 10-Q pursuant to the rules and regulations of the Securities and Exchange
Commission (“SEC”). However, in the opinion of management, these interim
financial statements include all the necessary adjustments to fairly present the
results of the interim periods presented. Management has considered for
disclosure any material subsequent events through November 16, 2009, the
date the financial statements were issued. The unaudited interim financial
statements should be read in conjunction with the audited financial statements
included in the Partnership's Form 10-K for the year ended December 31, 2008.
The results of operations for the three months and nine months ended September
30, 2009 may not necessarily be indicative of the results of operations for the
year ended December 31, 2009.
 
 NOTE
2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 In
addition to matters discussed further in this note, the Partnership’s
significant accounting policies are detailed in its audited financial statements
and notes thereto in the Partnership’s Form 10-K for the year ended December 31,
2008 filed with the SEC.
 
 Use
of Estimates
 
 Preparation
of financial statements in conformity with accounting principles generally
accepted in the United States of America requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
the disclosure of contingent assets and liabilities as of the date of the
financial statements and the reported amounts of revenues, costs and expenses
during the reporting period. The Partnership’s financial statements are based on
a number of significant estimates, including revenue and expense accruals,
depletion, fair value of derivative instruments and the probability of
forecasted transactions. Actual results could differ from these
estimates.
 
 Accounts
Receivable and Allowance for Possible Losses
 
 In
evaluating the need for an allowance for possible losses, the Partnership's MGP,
performs ongoing credit evaluations of its customers and adjusts credit limits
based upon payment history and the customer’s current creditworthiness, as
determined by review of its customers' credit information. Credit is extended on
an unsecured basis to many of its energy customers. At September 30, 2009 and
December 31, 2008, the Partnership's MGP's credit evaluation indicated that the
Partnership has no need for an allowance for possible losses.

 NOTE
2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)
 
 Revenue
Recognition
 
 The
Partnership generally sells natural gas and crude oil at prevailing market
prices.  Revenue is recognized when produced quantities are delivered
to a custody transfer point, persuasive evidence of a sales arrangement exists,
the rights and responsibility of ownership pass to the purchaser upon delivery,
collection of revenue from the sale are reasonably assured and the sales price
is fixed or determinable.  Revenues from the production of natural gas
and crude oil in which the Partnership has an interest with other producers are
recognized on the basis of the Partnership’s percentage ownership of working
interest or overriding royalty. Generally, the Partnership’s sales contracts are
based on pricing provisions that are tied to a market index, with certain
adjustments based on proximity to gathering and transmission lines and the
quality of its natural gas.
 
 Because
there are timing differences between the delivery of natural gas and oil and its
receipt of a delivery statement, the Partnership has unbilled revenues. These
revenues are accrued based upon volumetric data from the Partnership’s records
and estimates of the related transportation and compression fees which are, in
turn, based upon applicable product prices. The Partnership had unbilled trade
receivables at September 30, 2009 and December 31, 2008 of $3,248,200 and
$5,726,800, respectively, which are included in accounts receivable on the
Partnership’s Balance Sheets.
 
 Oil
and Gas Properties
 
 The
Partnership follows the successful-efforts method of accounting for oil and gas
producing activities. Oil and gas properties are recorded at
cost.  Depletion is determined on a field-by-field basis using the
units-of-production method for well and related equipment costs based on proved
developed reserves associated with each field. Depletion rates are determined
based on reserve quantity estimates and the capitalized costs of developed
producing properties.  In addition, accumulated depletion includes
impairment adjustments to reflect the write-down to fair market value of the oil
and gas properties. Maintenance and repairs are expensed as incurred. Major
renewals and improvements that extend the useful lives of the property are
capitalized. Oil is converted to gas equivalent basis (“Mcfe”) at the rate one
barrel equals 6 thousand cubic feet (“Mcf”).
 
 Upon the
sale or retirement of a complete field of a proved property, the cost is
eliminated from the property accounts, and the resultant gain or loss is
recorded in operations. Upon the sale or retirement of an individual well, the
net book value is credited to accumulated depletion. As a result of retirements
the Partnership is reclassified $12,500 from oil and gas properties, to
accumulated depletion for the nine months ended September 30, 2009.

      and gas properties consist of the following at the dates

 Impairment
of Oil and Gas Properties and Long-Lived Assets
 
 The
Partnership’s oil and gas properties are reviewed for impairment annually or
whenever events or changes in circumstances indicate that their carrying amounts
may not be recoverable. Oil and gas properties are reviewed for potential
impairments at the lowest levels for which there are identifiable cash
flows.
 
 The
review of the Partnership’s oil and gas properties is done on a field-by-field
basis by determining if the historical cost of proved properties less the
applicable accumulated depletion and abandonment is less than the estimated
expected undiscounted future cash flows. The expected future cash flows are
estimated based on the Partnership’s plans to continue to produce and develop
proved reserves. Expected future cash flow from the sale of production of
reserves is calculated based on estimated future prices. The Partnership
estimates prices based upon current contracts in place, adjusted for basis
differentials and market related information including published futures prices.
The estimated future level of production is based on assumptions surrounding
future levels of prices and costs, field decline rates, market demand and
supply, and the economic and regulatory climates. If the carrying value exceeds
such cash flows, an impairment loss is recognized for the difference between the
estimated fair market value (as determined by discounted future cash flows), and
the carrying value of the assets.
 
 The
determination of oil and natural gas reserve estimates is a subjective process,
and the accuracy of any reserve estimate depends on the quality of available
data and the application of engineering and geological interpretation and
judgment. Estimates of economically recoverable reserves and future net cash
flows depend on a number of variable factors and assumptions that are difficult
to predict and may vary considerably from actual results. In addition, reserve
estimates for wells with limited or no production history are less reliable than
those based on actual production. Estimated reserves are often subject to future
revisions, which could be substantial, based on the availability of additional
information which could cause the assumptions to be modified. The Partnership
cannot predict what reserve revisions may be required in future periods.There were no
impairments of oil and gas properties recorded by the Partnership for the three
months and nine months ended September 30, 2009 and 2008.
 
 Working
Interest
 
 The
Partnership agreement establishes that revenues and expenses will be allocated
to the MGP and limited partners based on their ratio of capital contributions to
total contributions, (“the working interest”). The MGP is also provided an
additional working interest of 7% as provided in the Partnership Agreement. Due
to the time necessary to complete drilling operations and accumulate all
drilling costs, estimated working interest percentage ownership rates are
utilized to allocate revenues and expenses until the wells are completely
drilled and turned on-line into production. Once the wells are completed, the
final working interest ownership of the partners is determined, and any
previously allocated revenues and expenses based on the estimated working
interest percentage ownership are adjusted to conform to the final working
interest percentage ownership. As of September 30, 2009 $247,500 of net earnings
resulting from the working interest adjustment was reclassified from the MGP’s
capital account to the limited partner’s capital account.

Adopted Accounting Standards
 
 In August
2009, the Financial Accounting Standards Board (“FASB”) issued Accounting
Standards Update 2009-05, Fair
Value Measurements and Disclosures (Topic 820) – Measuring Liabilities at Fair
Value (“Update 2009-05”). Update 2009-05 amends subtopic 820-10, “Fair
Value Measurements and Disclosures- Overall” and provides clarification for the
fair value measurement of liabilities in circumstances where quoted prices for
an identical liability in an active market are not available. The amendments
also provide clarification for not requiring the reporting entity to include
separate inputs or adjustments to other inputs relating to the existence of a
restriction that prevents the transfer of a liability when estimating the fair
value of a liability.  Additionally, these amendments clarify that
both the quoted price in an active market for an identical liability at the
measurement date and the quoted price for an identical liability when traded as
an asset in an active market when no adjustments to the quoted price of the
asset are required are considered Level 1 fair value measurements. These
requirements are effective for financial statements issued after the release of
Update 2009-05.  The Partnership adopted the requirements on September
30, 2009 and it did not have a material impact on its financial position,
results of operations or related disclosures.
 
 In June
2009, the FASB issued Accounting Standards Update 2009-01, Topic 105- Generally Accepted
Accounting Principles Amendments Based on Statements of Financial Accounting
Standards No. 168- The FASB Accounting Standards Codification and the Hierarchy
of Generally Accepted Accounting Principles (“Update 2009-01”). Update
2009-01 establishes the FASB Accounting Standards Codification (“ASC”) as the
single source of authoritative U.S. generally accepted accounting principles
recognized by the FASB to be applied by nongovernmental entities.  The
ASC supersedes all existing non-Securities and Exchange Commission accounting
and reporting standards.  Following the ASC, the FASB will not issue
new standards in the form of Statements, FASB Staff Positions, or Emerging
Issues Task Force Abstracts. Instead, the FASB will issue Accounting Standards
Updates, which will serve only to update the ASC.  ASC 105 is
effective for financial statements issued for interim and annual periods ending
after September 15, 2009.  Entities are not required to include
specific references to the ASC in their financial statements and, therefore, the
Partnership has removed all previous references to FASB authoritative guidance
and describes its accounting policies using a “plain English” approach. The
Partnership adopted the requirements of Update 2009-01 to its financial
statements on September 30, 2009 and it did not have a material impact to the
Partnership’s financial statement disclosures.
 
 In May
2009, the FASB issued ASC 855-10, Subsequent Events (“ASC
855-10”). ASC 855-10 establishes general standards of accounting for and
disclosure of events that occur after the balance sheet date but before
financial statements are issued or are available to be issued. The provisions
require management of a reporting entity to evaluate events or transactions that
may occur after the balance sheet date for potential recognition or disclosure
in the financial statements and provides guidance for disclosures that an entity
should make about those events. ASC 855-10 is effective for interim or annual
financial periods ending after June 15, 2009 and shall be applied prospectively.
The Partnership adopted the requirements of this standard on June 30, 2009 and
it did not have a material impact to its financial position or results of
operations or related disclosures. The adoption of these provisions does not
change the Partnership’s current practices with respect to evaluating, recording
and disclosing subsequent events.

Adopted Accounting Standards (Continued)
 
 In April
2009, the FASB issued ASC 820-10-65-4, Determining Fair Value When the
Volume and Level of Activity for the Asset or Liability Have Significantly
Decreased and Identifying Transactions That Are Not Orderly (“ASC
820-10-65-4”). ASC 820-10-65-4 applies to all fair value measurements and
provides additional clarification on estimating fair value when the market
activity for an asset has declined significantly. ASC 820-10-65-4 also require
an entity to disclose a change in valuation technique and related inputs to the
valuation calculation and to quantify its effects, if practicable. ASC
820-10-65-4 is effective for interim and annual periods ending after June 15,
2009, with early adoption permitted for periods ending after March 15,
2009.  The Partnership adopted the requirements of ASC 820-10-65-4 on
April 1, 2009 and its adoption did not have a material impact on the
Partnership’s financial position and results of operations.
 
 In April
2009, the FASB issued ASC 825-10-65-1, Interim Disclosures about Fair Value
of Financial Instruments (“ASC 825-10-65-1”), which requires an entity to
provide disclosures about fair value of financial instruments in interim
financial information. In addition, an entity shall disclose in the body or in
the accompanying notes of its summarized financial information for interim
reporting periods and in its financial statements for annual reporting periods
the fair value of all financial instruments for which it is practicable to
estimate that value, whether recognized or not recognized in the statement of
financial position. ASC 825-10-65-1 is effective for interim periods ending
after June 15, 2009, with early adoption permitted for periods ending after
March 15, 2009.  The Partnership adopted these requirements on April
1, 2009 and its adoption did not have a material impact on the Partnership’s
financial position and results of operations.
 
 In March
2008, the FASB issued ASC 815-10-50-1, Disclosures about Derivative
Instruments and Hedging Activities (“ASC 815-10-50-1”), to require
enhanced disclosure about how and why an entity uses derivative instruments, how
derivative instruments and related hedged items are accounted for and how
derivative instruments and related hedged items affect an entity’s financial
position, financial performance and cash flows. The Partnership adopted the
requirements of this section of ASC 815-10-50-1 on January 1, 2009 and it did
not have a material impact on its financial position or results of operations
(see Note 5).
 
 Modernization
of Oil and Gas Reporting
 
 In
December 2008, the SEC announced that it had approved revisions to its oil and
gas reporting disclosures by adopting amendments to Rule 4-10 of Regulation S-X
and Items 201, 801, and 802 of Regulation S-K. These new disclosure requirements
are referred to as “Modernization of Oil and Gas Reporting” and include
provisions that:
 
 ·
              Introduce
      a new definition of oil and gas producing activities. This new definition
      allows companies to include in their reserve base volumes from
      unconventional resources. Such unconventional resources include bitumen
      extracted from oil sands and oil and gas extracted from coal beds and
      shale formations.
 
 ·
              Report
      oil and gas reserves using an unweighted average price using the prior
      12-month period, based on the closing prices on the first day of each
      month, rather than year-end pricing. This should maximize the
      comparability of reserve estimates among companies and mitigate the
      distortion of the estimates that arises when using a single pricing
      date.

              Require
      additional disclosures regarding the qualifications of the chief technical
      person who oversees the Partnership’s overall reserve estimation process.
      Additionally, disclosures are required related to internal controls over
      reserve estimation, as well as a report addressing the independence and
      qualifications of a Partnership’s  reserves preparer or auditor
      based on Society of Petroleum Engineers
  criteria.
 
 The
Partnership will begin complying with the disclosure requirements in its annual
report on Form 10-K for the year ending December 31, 2009. The new rules may not
be applied to disclosures in quarterly reports prior to the first annual report
in which the revised disclosures are required. The Partnership is currently in
the process of evaluating the new requirements.

 NOTE
5 - DERIVATIVE INSTRUMENTS
 
 The
Partnership is exposed to certain risks relating to its ongoing business
operations. The risk is managed by using derivative instruments related to
commodity price risk. Forward contracts on natural gas and oil are entered into
to manage the price risk associated with forecasted sales of natural gas and
crude oil. The Partnership designates these derivatives as cash flow hedges and
the derivative instruments have been recorded as either assets or liabilities at
fair value on the balance sheets. The effective portion of the gain or loss on
the derivative is reported as a component of other comprehensive loss and
reclassified to earnings in the same period during which the hedged transaction
affects earnings. The following table summarizes the fair value of derivative
instruments as of September 30, 2009 and December 31, 2008, as well as the gain
or loss recognized for the three months and nine months ended September 30, 2009
and 2008, respectively. There were no gains or losses recognized in income for
ineffective derivative instruments for the three months and nine months ended
September 30, 2009 and 2008, respectively.

 Atlas
Energy, on behalf of the Partnership, from time to time enters into natural gas
and crude oil future option and collar contracts to hedge exposure to changes in
natural gas prices and oil prices. At any point in time, such contracts may
include regulated New York Mercantile Exchange (“NYMEX”) futures, options
contracts and non-regulated over-the-counter futures contracts with qualified
counterparties. NYMEX contracts are generally settled with offsetting positions,
but may be settled by the delivery of natural gas. Crude oil contracts are based
on a West Texas Intermediate ("WTI") index. These contracts have qualified and
been designated as cash flow hedges and recorded at their fair
values.
 
 At
September 30, 2009, the Partnership reflected a net hedge asset on its Balance
Sheets of $3,639,100, however unrealized gains of $6,842,300 which were required
to be recognized in net income which were related to impairment charges of the
Partnership’s oil and gas properties for the year ended December 31, 2008
results in a net unrealized accumulated loss of $3,203,200. Of the remaining
$3,203,200 net unrealized loss in accumulated other comprehensive loss at
September 30, 2009, if the fair values of the instruments remain at current
market values, the Partnership will reclassify $1,352,800 of net losses to its
Statements of Operations over the next twelve month period as these contracts
settle, and $1,850,400 of net losses in later periods. Actual amounts that will
be reclassified will vary as a result of future price changes. Ineffective hedge
gains or losses are recorded within the Statements of Operations while the hedge
contract is open and may increase or decrease until settlement of the contract.
The Partnership recognized no gains or losses during the three months and nine
months ended September 30, 2009 and 2008, respectively, for hedge
ineffectiveness or as a result of the discontinuance of cash flow
hedges.

 NOTE
6 - FAIR VALUE OF FINANCIAL INSTRUMENTS
 
 The
Partnership has established a hierarchy to measure its financial instruments at
fair value which requires it to maximize the use of observable inputs and
minimize the use of unobservable inputs when measuring fair value. The hierarchy
defines three levels of inputs that may be used to measure fair
value.
 
 Level 1–Quoted prices in
active markets for identical assets and liabilities that the reporting entity
has the ability to access at the measurement date.
 
 Level 2–Inputs other than
quoted prices included within Level 1 that are observable for the asset and
liability or can be corroborated with observable market data for substantially
the entire contractual term of the asset or liability.
 
 Level 3–Unobservable inputs
that reflect the entities own assumptions about the assumptions that market
participants would use in the pricing of the asset or liability and are
consequently not based on market activity, but rather through particular
valuation techniques.
 
 Assets
and Liabilities Measured at Fair Value on a Recurring Basis
 
 The
Partnership has certain assets and liabilities that are reported at fair value
on a recurring basis in its balance sheets. The following methods and
assumptions were used to estimate fair values.

 All of
the Partnership’s derivatives contracts are defined as Level 2. The
Partnership's natural gas and crude oil derivative contracts are valued based on
prices quoted on the NYMEX or WTI and adjusted by the respective counterparty
using various assumptions including quoted forward prices, time value,
volatility factors, and contractual prices for the underlying instruments.

 Assets
and Liabilities Measured at Fair Value on a Nonrecurring Basis
 
 The
Partnership has certain assets and liabilities that are reported at fair value
on a nonrecurring basis in its Balance Sheets. The following methods and
assumptions were used to estimate fair values.
 
 Asset Retirement
Obligations.  The Partnership estimates the fair value of asset
retirement obligations based on discounted cash flow projections using numerous
estimates, assumptions and judgments regarding such factors at the date of
establishment of an asset retirement obligation such as: amounts and timing of
settlements; the credit adjusted risk free rate of the Partnership; and
estimated inflation rates. There were no new asset retirement obligations
incurred for the three months and ninemonths ended September
30, 2009, respectively. There were new asset retirement obligations incurred for
the three months and nine months ended September 30, 2008 is as

 NOTE
7 - ASSET RETIREMENT OBLIGATION
 
 The
Partnership recognizes an estimated liability for the plugging and abandonment
of its oil and gas wells and related facilities. It also recognizes a liability
for future asset retirement obligations if a reasonable estimate of the fair
value of that liability can be made. The associated asset retirement costs are
capitalized as part of the carrying amount of the long-lived asset. The
Partnership also considers the estimated salvage value in the calculation of
depreciation, depletion and amortization.
 
 The
estimated liability is based on historical experience in plugging and abandoning
wells, estimated remaining lives of those wells based on reserve estimates,
external estimates as to the cost to plug and abandon the wells in the future,
and federal and state regulatory requirements. The liability is discounted using
an assumed credit-adjusted risk-free
interest rate. Revisions to the liability could occur due to changes in
estimates of plugging and abandonment costs or remaining lives of the wells, or
if federal or state regulators enact new plugging and abandonment
requirements.

 General
 
 We were
formed as a Delaware limited partnership on May 7, 2007, with Atlas Resources,
LLC as our Managing General Partner, or MGP, to drill natural gas development
wells. We have no employees and rely on our MGP for management, which in turn
relies on its parent company, Atlas Energy Resources, LLC (NYSE:ATN), or Atlas
Energy, for administrative services. On September 29, 2009 Atlas Energy
completed its merger with Atlas America, Inc. (NASDAQ:ATLS). In addition, Atlas
America changed its name to Atlas Energy, Inc.
 
 Our wells
are currently producing natural gas and, to a far lesser extent, oil which are
our only products. Most of our gas is gathered and delivered to market through
Laurel Mountain Midstream, LLC’s gas gathering system, a newly formed
joint-venture between Atlas Energy’s affiliate, Atlas Pipeline Partners, L.P.
(NYSE:APL) and The Williams Companies (NYSE:WMB). We do not plan to sell any of
our wells and will continue to produce them until they are depleted or become
uneconomical to produce, at which time they will be plugged and abandoned or
sold.

following table sets forth information relating to our production revenues,

 Natural Gas
Revenues.Our natural gas revenues were $3,084,900 and
$14,228,800 for the three months ended September 30, 2009 and 2008,
respectively, a decrease of $11,143,900 (78%). The $11,143,900 decrease in
natural gas revenues for the three months ended September 30, 2009 as compared
to the prior year similar period was attributable to a $3,082,700 decrease in
natural gas sales prices after the effect of financial hedges, which are driven
by market conditions, and an $8,061,200 decrease in production volumes.Our production volumes
decreased to 6,396 mcf per day for the three months ended September 30, 2009
from 14,755 mcf per day for the three months ended September 30, 2008, a
decrease of 8,359 mcf per day (57%).
 
 Our
natural gas revenues were $11,844,500 and $25,209,100 for the nine months ended
September 30, 2009 and 2008, respectively, a decrease of $13,364,600 (53%). The
$13,364,600 decrease in natural gas revenues for the nine months ended September
30, 2009 as compared to the prior year similar period was attributable to a
$4,305,100 decrease in natural gas sales prices after the effect of financial
hedges, which are driven by market conditions, and a $9,059,500 decrease in
production volumes. Our production volumes decreased to 7,660 mcf per day for
the nine months ended September 30, 2009 from 9,204 mcf per day for the three
ended September 30, 2008, a decrease of 1,544 mcf per day (17%).
 
 Oil Revenues. We drill wells
primarily to produce natural gas, rather than oil, but some wells have limited
oil production. Our oil revenues were $97,000 and $683,600 the three months
ended September 30, 2009 and 2008, respectively, a decrease of $586,600. The
$586,600 decrease in oil revenues for the three months ended September 30, 2009
as compared to the prior year similar period was attributable to a $394,800
decrease in production volumes and a $191,800 decrease in oil prices. Our
production volumes decreased to 30 bbls per day for the three months ended
September 30, 2009 from 70 bbls per day for the three months ended September 30,
2008, a decrease of 40 bbls per day (57%).
 
 Our oil
revenues were $83,400 and $1,302,600 the nine months ended September 30, 2009
and 2008, respectively, a decrease of $1,219,200 (94%). The $1,219,200 decrease
in oil revenues for the nine months ended September 30, 2009 as compared to the
prior year similar period was attributable to a $978,300 decrease in oil prices
and a $240,900 decrease in production volumes. Our production volumes decreased
40 bbls per day for the nine months ended September 30, 2009 from 48 bbls per
day for the nine months ended September 30, 2008, a decrease of 8 bbls per day
(17%).
 
 Expenses.Production
expenses were $1,509,100 and $2,283,000 for the three months ended September 30,
2009 and 2008, respectively, a decrease of $773,900 (34%). Production expenses
were $4,873,000 and $4,779,200 for the nine months ended September 30, 2009 and
2008, respectively, an increase of $93,800 (2%). The decrease for the three
months ended September 30, 2009 was due to lower transportation fees. The
increase for the nine months ended September 30, 2009 was due to higher
supervision fees due to more wells being on-line.
 
 Depletion
of oil and gas properties as a percentage of oil and gas revenues were 45% and
51% in the three months ended September 30, 2009 and 2008, respectively; and 40%
and 53% for the nine months ended September 30, 2008 and 2007, respectively.
These percentage changes were directly attributable to changes in revenues, oil
and gas reserve quantities, product prices, production volumes and changes in
the depletable cost basis of oil and gas properties.
 
 General
and administrative expenses for the three months ended September 30, 2009 and
2008 were $108,100 and $94,900, respectively, an increase of $13,200 (14%). For
the nine months ended September 30, 2009 and 2008 these expenses were $300,200
and $262,200, respectively, an increase of $38,000 (14%). These expenses include
third-party costs or services as well as the monthly administrative fees charged
by our MGP and vary from period to period due to the timing and billing of the
costs and services provided to the Partnership.

 Liquidity
and Capital Resources
 
 Cash
provided by operating activities increased $4,707,900 in the nine months ended
September 30, 2009 to $15,822,200 as compared to $11,114,300 for the nine months
ended September 30, 2008. This increase was due to an increase of a net non-cash
loss on derivative values of $6,613,200 and the change in accounts
receivable-affiliate increased operating cash flows by $12,813,100, partially
offset by a decrease in net earnings before depletion and accretion of
$14,721,000 in the nine months ended September 30, 2009 as compared to the nine
months ended September 30, 2009.
 
 Cash used
in financing activities increased $11,144,200 to $18,719,200 during the nine
months ended September 30, 2009, from $7,575,000 during the nine months ended
September 30, 2008. This increase was due to an increase in cash distributions
to partners.
 
 Our MGP
may withhold funds for future plugging and abandonment costs. Any additional
funds, if required, will be obtained from production revenues or borrowings from
our MGP or its affiliates, which are not contractually committed to make loans
to us. The amount that we may borrow may not at any time exceed 5% of our total
subscriptions, and we will not borrow from third-parties.
 
 The
Partnership is generally limited to the amount of funds generated by the cash
flows from our operations, which we believe is adequate to fund future
operations and distributions to our partners. Historically, there has been no
need to borrow funds from our MGP to fund operations.
 
 Critical
Accounting Policies
 
 The
discussion and analysis of our financial condition and results of operations are
based upon our financial statements, which have been prepared in accordance with
accounting principles generally accepted in the United States of America. On an
on-going basis, we evaluate our estimates, including those related to our asset
retirement obligations, depletion and certain accrued receivables and
liabilities. We base our estimates on historical experience and on various other
assumptions that we believe reasonable under the circumstances, the results of
which form the basis for making judgments about the carrying values of assets
and liabilities that are not readily apparent from other sources. Actual results
may differ from these estimates under different assumptions or conditions. A
discussion of our significant accounting policies we have adopted and followed
in the preparation of our financial statements is included within “Notes to
Financial Statements” in Part I, Item 1, “Financial Statements” in this
quarterly report and in our Annual Report on Form 10-K for the year ended
December 31, 2008.
 
 Subordination
by Managing General Partner
 
 Under the
terms of the Partnership agreement, the MGP may be required to subordinate up to
50% of its share of net production revenues of the Partnership to provide a
distribution to the limited partners equal to at least 10% of their agreed
subscriptions. Subordination is determined on a cumulative basis, in each of the
first five years of Partnership operations, commencing with the first
distribution of net revenues to the investor partners (August 2008). Since
inception of the program, the MGP has not been required to subordinate any of
its distributions to its limited partners.

 Recently
Adopted Accounting Standards
 
 In August
2009, the Financial Accounting Standards Board or FASB issued Accounting
Standards Update 2009-05, Fair
Value Measurements and Disclosures (Topic 820) – Measuring Liabilities at Fair
Value an Update 2009-05. Update 2009-05 amends subtopic 820-10, “Fair
Value Measurements and Disclosures- Overall” and provides clarification for the
fair value measurement of liabilities in circumstances where quoted prices for
an identical liability in an active market are not available. The amendments
also provide clarification for not requiring the reporting entity to include
separate inputs or adjustments to other inputs relating to the existence of a
restriction that prevents the transfer of a liability when estimating the fair
value of a liability. Additionally, these amendments clarify that both the
quoted price in an active market for an identical liability at the measurement
date and the quoted price for an identical liability when traded as an asset in
an active market when no adjustments to the quoted price of the asset are
required are considered Level 1 fair value measurements. These requirements are
effective for financial statements issued after the release of Update 2009-05.
We adopted the requirements on September 30, 2009 and it did not have a material
impact on our financial position, results of operations or related
disclosures.
 
 In June
2009, the FASB issued Accounting Standards Update 2009-01, Topic 105- Generally Accepted
Accounting Principles Amendments Based on Statements of Financial Accounting
Standards No. 168- The FASB Accounting Standards Codification and the Hierarchy
of Generally Accepted Accounting Principles an Update 2009-01. Update
2009-01 establishes the FASB Accounting Standards Codification or ASC as the
single source of authoritative U.S. generally accepted accounting principles
recognized by the FASB to be applied by nongovernmental entities. The ASC
supersedes all existing non-Securities and Exchange Commission accounting and
reporting standards.  Following the ASC, the FASB will not issue new
standards in the form of Statements, FASB Staff Positions, or Emerging Issues
Task Force Abstracts. Instead, the FASB will issue Accounting Standards Updates,
which will serve only to update the ASC. ASC 105 is effective for financial
statements issued for interim and annual periods ending after September 15,
2009. Entities are not required to include specific references to the ASC in
their financial statements and, therefore, we have removed all previous
references to FASB authoritative guidance and describes our accounting policies
using a “plain English” approach. We adopted the requirements of Update 2009-01
to our financial statements on September 30, 2009 and it did not have a material
impact to our financial statement disclosures.
 
 In May
2009, the FASB issued ASC 855-10, Subsequent Events or ASC
855-10.  ASC 855-10 establishes general standards of accounting for
and disclosure of events that occur after the balance sheet date but before
financial statements are issued or are available to be issued. The provisions
require management of a reporting entity to evaluate events or transactions that
may occur after the balance sheet date for potential recognition or disclosure
in the financial statements and provides guidance for disclosures that an entity
should make about those events. ASC 855-10 is effective for interim or annual
financial periods ending after June 15, 2009 and shall be applied
prospectively.  We adopted the requirements of this standard on June
30, 2009 and it did not have a material impact to our financial position or
results of operations or related disclosures. The adoption of these provisions
does not change our current practices with respect to evaluating, recording and
disclosing subsequent events.
 
 In April
2009, the FASB issued ASC 820-10-65-4, Determining Fair Value When the
Volume and Level of Activity for the Asset or Liability Have Significantly
Decreased and Identifying Transactions That Are Not Orderly or ASC
820-10-65-4. ASC 820-10-65-4 applies to all fair value measurements and provides
additional clarification on estimating fair value when the market activity for
an asset has declined significantly. ASC 820-10-65-4 also require an entity to
disclose a change in valuation technique and related inputs to the valuation
calculation and to quantify its effects, if practicable. ASC 820-10-65-4 is
effective for interim and annual periods ending after June 15, 2009, with early
adoption permitted for periods ending after March 15, 2009. We adopted the
requirements of ASC 820-10-65-4 on April 1, 2009 and its adoption did not have a
material impact on our financial position and results of
operations.

  In April
2009, the FASB issued ASC 825-10-65-1, Interim Disclosures about Fair Value
of Financial Instruments or ASC 825-10-65-1, which requires an entity to
provide disclosures about fair value of financial instruments in interim
financial information. In addition, an entity shall disclose in the body or in
the accompanying notes of its summarized financial information for interim
reporting periods and in its financial statements for annual reporting periods
the fair value of all financial instruments for which it is practicable to
estimate that value, whether recognized or not recognized in the statement of
financial position. ASC 825-10-65-1 is effective for interim periods ending
after June 15, 2009, with early adoption permitted for periods ending after
March 15, 2009.  We adopted these requirements on April 1, 2009 and
its adoption did not have a material impact on our financial position and
results of operations.
 
 In March
2008, the FASB issued ASC 815-10-50-1, Disclosures about Derivative
Instruments and Hedging Activities or ASC 815-10-50-1, to require
enhanced disclosure about how and why an entity uses derivative instruments, how
derivative instruments and related hedged items are accounted for and how
derivative instruments and related hedged items affect an entity’s financial
position, financial performance and cash flows. We adopted the requirements of
this section of ASC 815-10-50-1 on January 1, 2009 and it did not have a
material impact on our financial position or results of operations (see Note
5).
 
 Modernization
of Oil and Gas Reporting
 
 In
December 2008, the Securities and Exchange Commission or SEC announced that it
had approved revisions to its oil and gas reporting disclosures by adopting
amendments to Rule 4-10 of Regulation S-X and Items 201, 801, and 802 of
Regulation S-K. These new disclosure requirements are referred to as
“Modernization of Oil and Gas Reporting” and include provisions
that:
 
 ·
              Introduce
      a new definition of oil and gas producing activities. This new definition
      allows companies to include in their reserve base volumes from
      unconventional resources. Such unconventional resources include bitumen
      extracted from oil sands and oil and gas extracted from coal beds and
      shale formations.
 
 ·
              Report
      oil and gas reserves using an unweighted average price using the prior
      12-month period, based on the closing prices on the first day of each
      month, rather than year-end pricing. This should maximize the
      comparability of reserve estimates among companies and mitigate the
      distortion of the estimates that arises when using a single pricing
      date.
 
 ·
              Permit
      companies to disclose their probable and possible reserves on a voluntary
      basis. Current rules limit disclosure to only proved
    reserves.
 
 ·
              Update
      and revise reserve definitions to reflect changes in the oil and gas
      industry and new technologies. New updated definitions include “by
      geographic area” and “reasonable
certainty.”
 
 ·
              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.
 
 ·
              Require
      additional disclosures regarding the qualifications of the chief technical
      person who oversees the Partnership’s overall reserve estimation process.
      Additionally, disclosures are required related to internal controls over
      reserve estimation, as well as a report addressing the independence and
      qualifications of a Partnership’s reserves preparer or auditor based on
      Society of Petroleum Engineers
criteria.
 
 We will
begin complying with the disclosure requirements in its annual report on Form
10-K for the year ending December 31, 2009. The new rules may not be applied to
disclosures in quarterly reports prior to the first annual report in which the
revised disclosures are required. We are currently in the process of evaluating
the new requirements.

 ITEM
4.  CONTROLS AND PROCEDURES
 
 Evaluation
of Disclosure Controls and Procedures
 
 The
Partnership maintains disclosure controls and procedures that are designed to
ensure that information required to be disclosed in Securities and Exchange Act
of 1934 reports is recorded, processed, summarized and reported within the time
periods specified in the SEC’s rules and forms, and that such information is
accumulated and communicated to the MGP’s management, including the chief
executive officer and the chief financial officer, as appropriate, to allow
timely decisions regarding required disclosure. In designing and evaluating the
disclosure controls and procedures, the MGP’s management recognized that any
controls and procedures, no matter how well designed and operated, can provide
only reasonable assurance of achieving the desired control objectives, and the
MGP’s management necessarily was required to apply its judgment in evaluating
the cost-benefit relationship of possible controls and procedures.
 
 Under the
supervision of the chief executive officer and chief financial officer, the MGP
has carried out an evaluation of the effectiveness of the Partnership’s
disclosure controls and procedures as of the end of the period covered by this
report. Based upon that evaluation, the chief executive officer and chief
financial officer concluded that the Partnership’s disclosure controls and
procedures are effective at the reasonable assurance level at September 30,
2009.
 
 There
have been no changes in the Partnership’s internal control over financial
reporting during our most recent fiscal quarter that have materially affected,
or are reasonably likely to materially effect, our internal control over
financial reporting.
