CGG has extended its data library of shale acreage in the United States by completing a vast three-year multi-client 3D land seismic program targeting the Marcellus Shale Fairway. The Marcellus Shale is considered to be a leading shale play for future natural gas exploration and production in the United States.
CGG conducted the 1,566-square-mile program in six phases in Lycoming, Tioga, Clinton, Centre and Clearfield Counties in Central Pennsylvania. It is believed to be the largest combined onshore seismic survey ever acquired in the continental United States.
As the terrain in Central Pennsylvania gradually became more rugged and mountainous, CGG switched from deploying the Sercel 428XL cable acquisition system to using the Sercel UNITE® wireless acquisition system to acquire the complex seismic program.
