Gulf-based Cox Oil has entered into an agreement to acquire Energy XXI Gulf Coast in $322 million. Cox Oil will secure all of the outstanding shares of Energy XXI’s common stock for $9.10/share, as part of the agreement. This will effectively terminate Energy XXIs partnership with Orinoco Natural Resources LLC announced last month. Upon completion of the deal, Cox Oil’s production will be boosted to more than 61,000 boe/d.
