TGS will perform a Powder River basin 3D seismic survey in Johnson County, Wyo. The Voyager 3D survey is a multi-client, industry-funded venture expected to complete in December 2021, with final products available in second-quarter 2022.
The survey will encompass about 555 sq km and is situated in the high potential trend north of the basin, where the prospective stratigraphic section of stacked reservoirs exceeds 5,000 ft in thickness. Unconventional targets include Niobrara and Mowry source rocks, along with numerous historically productive formations including upper and lower Cretaceous sandstones and the Pennsylvanian, currently exploited with unconventional technologies.
The data will be processed by TGS using onshore imaging technology for greater reservoir understanding. The Voyager 3D survey is complemented by a fully interpreted regional basin stratigraphic model derived from a library of high-quality well data. More than 41,000 LAS logs, 38,700 ARLAS, and over 145,000 raster logs are immediately available for Powder River basin.
