Acquisitions in 2012 added 35.0 MMBoe, all of which related to the purchase of reserves from Eagle Energy Production, LLC (“Eagle”) that was effective October 1, 2012. At year-end 2012, the Oklahoma reserves totaled 38.7 MMBoe, comprised of 38% crude oil, 22% NGLs, and 40% natural gas. All in, including acquisitions, drill bit additions, and revisions, Midstates replaced 1,446% of total 2012 production. Revisions to previous reserve estimates totaled 3.0 MMBoe. While West Gordon accounted for 1.6 MMBoe of those revisions, net reserves at West Gordon remained largely unchanged due to reserve additions from drilling activities in the north fault block.Midstates’ 2012 proved reserves had a net present value discounted at 10% (“PV-10”) of $1,489 million, up 115% from $693 million at year-end 2011. John Crum, Midstates’ CEO and President commented, “We are very pleased with the significant growth we achieved in our proved reserves during 2012 both organically in Louisiana and from the Eagle acquisition. We grew our Louisiana reserve base by 40% through successful drilling activities and increased proved reserves by 38.7 MMBoe through the acquisition and subsequent drilling of the Eagle properties. Importantly, Midstates replaced greater than 14 times its total 2012 production at a competitive all-in finding, development, and acquisition cost of approximately $20 to $23 per Boe based on preliminary cost estimates.” Crum continued, “Our 2013 drilling program will provide the opportunity to further grow reserves. We will also look at increasing acreage in our existing focus areas in Louisiana and Oklahoma/Kansas and to adding a potential third core area to our portfolio.” About Midstates Petroleum Company, Inc.
