DENVER, May 6, 2014 /PRNewswire/ -- Cimarex Energy Co. (NYSE: XEC) today announced that it has signed a purchase and sale agreement to acquire oil and gas assets primarily in the Cana- Woodford shale play in Western Oklahoma for $497.4 million in cash. Simultaneously, Cimarex entered into an agreement with Devon Energy (NYSE: DVN) to sell at closing a 50 percent interest in these assets for $248.7 million. The acquisition is expected to close on or before June 30, 2014, and is subject to customary conditions and purchase price adjustments. Cimarex's share of the assets includes its estimate of proved developed reserves of approximately 140 billion cubic feet equivalent (64 percent gas) at January 1, 2014, current production of approximately 35 million cubic feet equivalent per day (63 percent gas) and 50,000 net acres, including 30,000 net acres in the Cana- Woodford area and oil-rich East Cana area. Approximately 65 percent of the proved developed reserves are associated with properties in which Cimarex already owns a working interest. Cimarex Chairman and CEO, Tom Jorden, said, "This acquisition is a perfect bolt-on for Cimarex as it consolidates working interest ownership in the Cana core infill development project area while adding exposure to other western Oklahoma oil and gas plays." The acquisition will be funded with bank debt. Cimarex plans to discuss this transaction in more detail on its first quarter conference scheduled to take place at 11:00am Mountain time on May 7, 2014.
