OKLAHOMA CITY, Dec. 22, 2011 /PRNewswire/ -- SandRidge Energy, Inc. ("SandRidge") (NYSE: SD) announced today that it has entered into a Joint Venture ("JV") with a subsidiary of Repsol YPF, S.A., a leading international energy company based in Madrid, Spain. Under the agreement, SandRidge will sell an approximate 25% non-operated working interest, or 250,000 net acres, in the Extension Mississippian play located in Western Kansas and an approximate 16% non-operated working interest, or 113,636 net acres, in its Original Mississippian play. The 363,636 net acres in total will be sold to Repsol for an aggregate transaction value of $1 Billion. Repsol will pay $250 million in cash at closing and the remainder in the form of a drilling carry. In addition to paying for its working interest share of development costs, Repsol will pay an amount equal to 200% of its working interest to fund a portion of SandRidge's cost of development until the additional $750 million drilling carry obligation is satisfied. Based on current drilling expectations, SandRidge anticipates the drilling carry obligation to be satisfied within three years. The JV will exclude all wells and acreage within the associated spacing units spudded prior to January 1, 2012 and all wells and acreage associated with SandRidge Mississippian Trust I. The transaction is expected to close in the first quarter and is subject to certain closing conditions. Tom Ward, Chairman and CEO, stated, "We are excited to announce this Joint Venture with Repsol, a global energy leader, and we are pleased that they share our confidence in the development potential of this vast Mississippian oil play. We compare the scope of this play to the Bakken and believe it will be transformational for the Mid-Continent region of the United States. SandRidge has led the way in developing the Mississippian Play and has now drilled more than 195 horizontal wells, representing nearly half of all the horizontal wells drilled in the play to date. As a result of the drilling carry and its lower working interest, SandRidge's 2012 CapEx is expected to decline to $1.6 Billion from a previous budget of $1.8 Billion. This JV with Repsol puts us on a clear path to bridge the 2012 funding gap with non-debt capital and to execute our three year plan to triple EBITDA and double oil production while lowering our debt to EBITDA ratio.
