HOUSTON, July 29 -- Energy Corp. of America, a private Charleston, W.Va., operator, is developing gas production from Devonian Marcellus shale in Greene County in the southwest corner of Pennsylvania.
In May, the company began a 3-year program to develop 10,000 acres it holds in the county. It is producing 8 MMcfd of gas from wells completed only in the Marcellus and more than 15 MMcfd from vertical wells in which it has commingled Marcellus gas with output from other formations.
Two rigs are drilling horizontal wells to the Marcellus, which lies at about 8,000 ft true vertical depth in Greene County. The company holds more than 1 million acres in the Appalachian basin on which the Marcellus varies in depth from 3,000 ft to 8,000 ft.
ECA has drilled 155 Marcellus vertical and horizontal Marcellus wells, and initial potentials of the completed wells have ranged from 500 Mcfd to 3 MMcfd. The wells produce little condensate.
ECA drilled one of the first horizontal wells in Greene County in 2007 as part of a joint venture with an industry partner, but it operates and wholly owns almost all of its wells.
The company owns more than 40 miles of pipeline and has sufficient capacity available on interstate systems to market its production.
