The company's efforts have paid off. By shifting focus from vertical Cotton Valley wells to the Haynesville, Goodrich decreased its total proved developed finding and advancement costs from $3. 21 an Mcf of gas equivalent to $2. 38 an Mcfe from 2009 to 2010. With oil costs trading much greater than gas on a Btu equivalent basis, Goodrich also is targeting the oil window of the Eagle Ford Shale.
Although these wells take ability, time, and cash to plan and construct, business officials state they think they can achieve 50 plus percent rois. Drilling wells in either play needs rigs with the best equipment, says Denney. He states leading drives are important because they enable pumping and turning the drill string while coming out of the hole, which is essential at times for hole cleaning.
Leading drives likewise optimize directional drilling performance. Drawworks that can provide at least 1,500 horse power are likewise key, Denney adds. " 3000 hp drilling rigs believe in high horse power," he worries. "A 1,500-horsepower rig carries a premium over a 1,000-horsepower rig, however it speeds journeys and puts less pressure on the equipment. We get our money's worth." Simply as crucial as the drawworks and leading drive is having powerful mud pumps on the rig, Denney says.

"That horse power is required for mud hydraulics to keep the hole tidy, and to drive the downhole motor and other equipment. We have actually accomplished up to 6,000-foot laterals to date, and we are targeting 9,000-foot long laterals in the near future." In lots of cases, it makes good sense for the rig to have the capability to skid, Denney states.
"In the Eagle Ford, if we can skid, our drilling costs can be minimized as much as $500,000 a well," he states. Goodrich Petroleum is far from the only business that needs "high-spec" rigs with effective leading drives, raising systems and pumps. According to industry sources, rigs with bigger (+1,000) horsepower rankings account for an estimated 60 percent of the active rig fleet.
