Form 10-K for the Fiscal Year Ended December 31, 2018 Notes to Consolidated Financial Statements Supplementary Information on Oil, Natural Gas and Natural Gas Liquid Reserves (Unaudited) Estimated Quantities of Proved Oil, NGL and Natural Gas Reserves, page 68 1. The disclosure provided on page 6 related to the Partnership's drilling activity indicates six new wells were drilled in October and November 2017 with costs incurred of approximately $1.3 million in the year ended December 31, 2017. The disclosure also indicates two of these wells were completed in March 2018 and the remaining four wells were completed in April, June and July of 2018 with costs incurred of approximately $6.5 million in the year ended December 31, 2018. As 83% of the total cost of drilling and completing these wells was not incurred until 2018, tell us why you considered the proved undeveloped reserves attributable to these six wells to be converted to proved developed status during 2017. Refer to Rule 4-10(a)(6) of Regulation S-X. David McKenney Energy 11, L.P. November 7, 2019 Page 2 Exhibits and Financial Statement Schedules Exhibit 99.1, page 81 2. Disclosure in the reserve report indicates the Partnership supplied an expense model to be used in the preparation of the reserves and related cash flows in which the operating costs are forecast to scale down from $25,000 per well per month in year one to $7,500 per well per month in year eight and then are held constant at $6,800 per well per month in year fourteen and through the end of the well life. Based on the definition of proved reserves in Rule 4-10(a)(22) of Regulation S-X, explain to us why you consider a change in the existing economic conditions and operating methods resulting in a projected reduction in future operating costs to be reasonably certain. As part of your response, provide us with supporting documentation of actual historical cost reductions or contractual arrangements in place as of fiscal year end that achieve the cost reductions shown in your reserve report. We remind you that the company and its management are responsible for the accuracy and adequacy of their disclosures, notwithstanding any review, comments, action or absence of action by the staff. You may contact John Hodgin, Petroleum Engineer, at (202) 551-3699 if you have questions regarding engineering comments.
