EV Energy Partners is a master limited partnership controlled by EnerVest, an oil-and-gas company based in Houston.
The firm reported that its 2012 profits were up 20 percent to $66.1 million. Production was up 47 percent for the second quarter 2012: 10.7 billion cubic feet of natural gas, 282,000 barrels of oil and 403,000 barrels of natural gas liquids or 14.8 billion cubic feet of equivalent.
EV Energy Partners and affiliates are the largest conventional oil and gas producer in Ohio. It has accumulated 764,219 net acres and has 8,713 conventional wells in Ohio. It produces 25 percent of the natural gas produced in Ohio before the Utica shale boom.
It has also partnered with Chesapeake Energy and France’s largest oil company in Ohio’s Utica shale and has its own Utica holdings.
Total SA gained a 25 percent stake in 619,000 acres in 10 Ohio counties. That includes about 542,000 acres leased by Chesapeake and about 77,000 acres leased by EnerVest. Chesapeake got $2.03 billion and Texas-based EnerVest got $290 million in the deal.
The joint venture will likely have more than 500 wells by Dec. 31, 2014, CEO Mark Houser said.
To date, five joint venture Ohio wells are producing, 12 are either flow testing or shut down, 15 are being allowed to settle, 17 are being completed, three are being drilled and 11 being financially analyzed.
