The company also closed on the previously announced divestiture of certain assets in its Altamont acreage in the Uinta Basin.
The aggregate cash paid for the acquired properties was approximately $245 million, subject to post-closing adjustments, while the divested properties generated estimated proceeds of approximately $180 million, also subject to post-closing adjustments.
EP Energy president and CEO Russell Parker said: "We are pleased to deliver on an early achievement for the company under the new leadership team.
"The acquisition is the largest to date for the company, and we were able to complete the transactions in a balance sheet friendly manner bringing forward value from the divestiture. We are also pleased that our team has already integrated the newly acquired assets into our operations. We now look to further optimize these assets and grow production."
