Eastern Division

Eastern Division

ECA began its operations on the east coast in the Appalachian Basin, the oldest producing basin in the country, and has been active there for more than 50 years. ECA owns more than 900,000 acres from New York to Tennessee, and operates more than 4,400 wells and 5,000 miles of pipeline.

ECA has more than 10,000 drilling locations, with more than 20 TCF of resource base and more than 500 BCF of proved reserves. ECA also has the capability to transport more than 500 mmcf/d through multiple pipeline systems. In the past five years, ECA has drilled as many as 100 wells in a year, with up to six active drilling rigs operating at one time.

One of the earliest operators in the lucrative Marcellus shale region, ECA began testing wells in this play in the late 1970s in partnership with the Department of Energy. In 2006 ECA began its modern development of the region and has since drilled more than 375 wells from New York to Kentucky. Currently, ECA is actively developing its Marcellus acreage in Pennsylvania and West Virginia, where a vast majority of its recent wells have been drilled using innovative horizontal drilling technology.

Rocky Mountain Division

Rocky Mountain DivisionECA holds multiple high-potential oil and gas prospects in the Rocky Mountain region and is actively pursuing multiple unconventional targets throughout Montana and Wyoming. ECA has a developed heavy oil field, shallow gas holdings, and owns and operates existing gathering and transportation infrastructure.

ECA has drilled and produced gas from multiple zones there, has had significant development in the Deep Wilcox trend, and has set multiple world records drilling high-pressure, high-temperature horizontal wells in that area. ECA is also continually evaluating new prospects and opportunities throughout the region.

International Division
