Organization and Basis of Presentation   The condensed financial statements of Reef Global Energy VII, L.P. (the “Partnership”) have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosure normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to those rules and regulations. We have recorded all transactions and adjustments necessary to fairly present the financial statements included in this Quarterly Report on Form 10-Q (this “Quarterly Report”). The adjustments are normal and recurring. The following notes describe only the material changes in accounting policies, account details, or financial statement notes during the first six months of 2013. Therefore, please read these unaudited condensed financial statements and notes to unaudited condensed financial statements together with the audited financial statements and notes to financial statements contained in the Partnership’s Annual Report on Form 10-K for the year ended December 31, 2012 (the “Annual Report”).  The results of operations for the three and six month periods ended June 30, 2013 are not necessarily indicative of the results that may be expected for the year ending December 31, 2013.   Going Concern   The accompanying financial statements have been prepared assuming the Partnership is a going concern, which assumption contemplates the realization of assets and satisfaction of liabilities in the normal course of business. Our independent registered public accounting firm’s opinion included in our Annual Report includes an explanatory paragraph indicating substantial doubt about our ability to continue as a going concern.   During the first quarter of 2013, the Partnership sold its interest in the Sand Dunes property, which was comprised of four shut-in wells, three productive wells, and one salt water disposal well. As a result of this sale, the Partnership has two remaining  properties, one of which was shut-in at June 30, 2013 awaiting a workover proposal from the operator. The producing property has an estimated remaining economic reserve life of  18 months utilizing current prices, costs, and projected production volumes at June 30, 2013. The Partnership has no plans to sell its interests in either of these two properties or to drill additional wells. The Partnership also has no plans to engage in commodity futures trading or hedging activities. Finally, the estimated economic reserve life of Partnership wells is computed based upon operating revenues and costs and does not consider Partnership general and administrative costs. Future cash flows generated from these two wells will be significantly impacted by actual prices received, and by actual production volumes. Current projections indicate that subsequent to June 30, 2013, revenues generated from crude oil and natural gas sales will not be sufficient to cover operating expenses and general and administrative costs. Reef Oil & Gas Partners, L.P. (“Reef”), as the Partnership’s managing general partner and sole general partner, may be required to provide additional capital contributions to the Partnership should working capital and future cash generated from crude oil and natural gas sales not be sufficient to  settle all  remaining asset retirement obligations and general and administrative costs. These factors raise substantial doubt about the ability of the Partnership to continue as a going concern.  The financial statements do not include any adjustments relating to the recoverability and classification of asset carrying amounts or the amount and classification of liabilities that might result should the Partnership be unable to continue as a going concern. The managing general partner continues to evaluate several options related to the Partnership, including the possible sale of marketable assets, as a result of these declining cash flows.   </div>falsefalsefalsenonnum:textBlockItemTypenaThe entire disclosure for organization, consolidation and basis of presentation of financial statements disclosure.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name FASB Interpretation (FIN) -Number 46R -Paragraph 4, 14, 15 -LegacyDoc This reference is SUPERSEDED by the Accounting Standards Codification effective for interim and annual periods ending after September 15, 2009.
