Midstates Petroleum Company, Inc. (NYSE: MPO) (the “Company” or “Midstates”) today provided an update on drilling operations and additional information on fourth quarter 2012 and first quarter 2013 production. The Company said its fourth quarter 2012 production averaged 15,592 net barrels of oil equivalent per day (Boe/d) compared with guidance of 15,100 to 15,600 Boe/d. Production from Oklahoma operations totaled 7,207 Boe/d while production from Louisiana operations totaled 8,385 Boe/d. Midstates also stated that its production for the month of December averaged 16,643 net Boe/d, of which 8,174 Boe/d were from operations in Oklahoma while 8,469 Boe/d were from operations in Louisiana. John Crum, Midstates’ CEO and President commented, “We are extremely pleased with our production volume growth in the fourth quarter. The integration of the Mississippian Lime operations and the Eagle team into Midstates has gone very smoothly, and the results announced today are a clear indication of how well that effort has proceeded.” During the fourth quarter, Midstates had four rigs active in its Mississippian Lime horizontal program in Oklahoma, spud 13 operated wells and placed a total of 14 operated wells into production. Three of the rigs were focused on drilling in the core of Midstates’ acreage while the fourth was used to test and/or retain acreage outside of the core area. At December 31, 2012, four wells were drilling and nine were awaiting completion or connection to pipelines. Overall, the wells continue to show results that are consistent with Midstates’ expectations. In Louisiana, during the fourth quarter of 2012, the Company drilled or sidetracked 14 vertical wells as planned at Pine Prairie, including eight wells in its shallow program and six wells in its Wilcox program. In the DeQuincy area, horizontal wells brought on production during 2012 continue to show encouraging results. At North Cowards Gully, the McFatter 8H-1 was drilled to a total measured depth of 16,870 feet including a 3,350-foot lateral and is currently undergoing stimulation. The McFatter 8H-1 is a follow up well to the very successful Upper Wilcox “B” Musser Davis 8H-1 well that was completed in September 2012 and had an initial 14-day average gross production rate of 1,649 Boe/d. The well has produced a total of approximately 122,000 Boe (73% oil) from inception of production through January 15, 2013. The Company believes it could have over 20 more potential horizontal well locations at North Cowards Gully for future drilling.
