Asker, Norway [19 December 2019] – TGS announced today that it has completed a transaction to purchase over 800 square miles of onshore 3D seismic surveys from a U.S. based E&P company. The data is available for licensing immediately.

This transaction supports TGS’ onshore growth strategy with the addition of key surveys, most notably in the SCOOP-STACK of the Anadarko Basin, Powder River Basin, and Permian Basin. Furthermore, this purchase complements TGS’ leading seismic data offering in the onshore United States and offers operators a more comprehensive onshore seismic library from which to enhance their exploration efforts in significant hydrocarbon-bearing basins.

Kristian Johansen, CEO at TGS commented, “These new datasets strengthen our position in core areas of onshore US and expand our library coverage in new prospective areas.  In combination with our extensive library of enhanced well data products, including log reconstruction via machine learning (ARLAS), we continue to offer the most complete subsurface data to shale players in the US.”
