 As provided in the Partnership Agreement, as amended (the Amended
 Partnership Agreement), a first right of presentment valuation was
 computed during the first quarter of 2015. The per-unit value was
 determined to be $9,765 based on the valuation date of
 December&amp;#xA0;31, 2014. The Partnership will not repurchase any
 Investing Partner Units (Units) during the first half of 2015 as a
 result of the Partnership&amp;#x2019;s limited amount of cash available
 for discretionary purposes. The Partnership is not in a position to
 predict how many Units will be presented for repurchase during the
 remainder of 2015 and cannot, at this time, determine if the
 Partnership will have sufficient funds available to repurchase any
 Units. Pursuant to the Amended Partnership Agreement, the
 Partnership has no obligation to purchase any Units presented to
 the extent it determines that it has insufficient funds for such
 purchases.&lt;/p&gt;

 The preparation of financial statements in conformity with U.S.
 GAAP 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. Significant estimates with
 regard to these financial statements include the estimate of proved
 oil and gas reserves and related present value estimates of future
 net cash flow therefrom and asset retirement obligations. Actual
 results could differ from those estimates.&lt;/p&gt;

 As of March&amp;#xA0;31, 2015, the Partnership&amp;#x2019;s significant
 accounting policies are consistent with those discussed in Note 2
 of its consolidated financial statements contained in the Annual
 Report on Form 10-K for the fiscal year ended December&amp;#xA0;31,
 2014.&lt;/p&gt;

 In May 2014, the Financial Accounting Standards Board (FASB) and
 the International Accounting Standards Board (IASB) issued a joint
 revenue recognition standard, ASU 2014-09. The new standard removes
 inconsistencies in existing standards, changes the way companies
 recognize revenue from contracts with customers, and increases
 disclosure requirements. The guidance requires companies to
 recognize revenue to depict the transfer of goods or services to
 customers in amounts that reflect the consideration to which the
 company expects to be entitled in exchange for those goods or
 services. ASU 2014-09 is effective for annual and interim periods
 beginning after December&amp;#xA0;15, 2016. The standard is required to
 be adopted using either the full retrospective approach, with all
 prior periods presented adjusted, or the modified retrospective
 approach, with a cumulative adjustment to retained earnings on the
 opening balance sheet.&amp;#xA0;The Partnership is currently evaluating
 the level of effort needed to implement the standard, the impact of
 adopting this standard on its consolidated financial statements,
 and whether to use the full retrospective approach or the modified
 retrospective approach.&lt;/p&gt;

 Certain assets and liabilities are reported at fair value on a
 recurring basis in the Partnership&amp;#x2019;s consolidated balance
 sheet. As of March&amp;#xA0;31, 2015, and December&amp;#xA0;31, 2014, the
 carrying amounts of the Partnership&amp;#x2019;s current assets and
 current liabilities approximated fair value because of the
 short-term nature or maturity of these instruments.&lt;/p&gt;
