Western USA
Explore historic and new plays in several prominent basins
CGG’s Western U.S. library contains an extensive amount of seismic data, providing subsurface imaging for several areas of interest. The North Dakota data sets identify several oil plays within the Williston Basin, while the Wyoming data sets focus on both historic and new oil and gas plays. Large reserves lie within several basins throughout the state of Wyoming, and CGG’s surveys were designed primarily to target these Cretaceous formations. CGG’s library consists of 692 mi2 in the Washakie Basin, 178 mi2 in the Wind River Basin, 1,324 mi2 in Green River Basin, and 935 mi2 in the Powder River Basin.

Big Cat
One of the most recent additions to CGG’s Western U.S. data library is Big Cat 3D. Expanding our coverage over the Powder River Basin, this 354 mi2 survey in Johnson County, Wyoming, targets the Shannon, Sussex, Niobrara, Frontier, Mowry, Muddy and Minnelusa formations. The survey was recorded using UNITE telemetry along with CGG’s patented EmphaSeis™ low-frequency sweep. The data has been processed using CGG’s advanced imaging technology and delivers high-quality data allowing our clients to make more informed decisions for exploration and development.
