HOUSTON (12 February 2019) – TGS announces a new multi-client onshore 3D seismic survey, Railgun 3D, located within the Powder River Basin.

Railgun 3D will encompass approximately 680 km2 in Converse and Campbell Counties, Wyoming. The high-resolution survey is ideally located in the high potential trend core of the basin where the prospective stratigraphic section of stacked reservoirs exceeds 5000 ft in thickness.  Unconventional targets include two world class source rocks, the Niobrara and Mowry, along with numerous historically productive tight sand formations including the Turner, Sussex, Shannon, Parkman, Frontier and Teapot, that are now being exploited successfully with unconventional technologies.

Recording will commence in Q3 2019 and will be completed before the end of the year. The data will be processed by TGS utilizing its modern land imaging technology to provide clients with greater reservoir understanding. The Railgun 3D is complemented by TGS' extensive geologic products which include a fully interpreted regional basin stratigraphic model that is analytics-ready, derived from an extensive library of high-quality well data.  More than 41,000 LAS logs and over 145,000 raster logs are immediately available for the Powder River Basin.

"TGS’ entry into the Powder River Basin is consistent with our strategy to identify prolific and high potential onshore plays where the application of modern seismic can deliver significant benefits to the exploration and production of hydrocarbons,” stated Kristian Johansen, CEO for TGS.  “Through the Railgun 3D, TGS establishes a solid position in this known hydrocarbon producing province that will enhance our current library offerings and provide additional opportunities for growth in this important basin.”
