TGS announces expansion of its 2018 onshore seismic activity with third project in the Anadarko Basin

HOUSTON, TX (12 April 2018) - TGS further expands its 2018 onshore seismic activity with the announcement of the Gloss Mountain 3D seismic survey. Gloss Mountain is a significant addition to our industry leading geoscience data position in the SCOOP/STACK area of the Anadarko Basin. This project will encompass a minimum of 900 sq. km in Major and Woods counties Oklahoma, just north of TGS' previously announced Canton 3D and our existing Loyal Complex 3D.

Permitting of the survey is in progress, with data acquisition expected to begin in Q3 2018. Preliminary data will be available Q1 2019, with final data in Q2 2019. The data will be processed by TGS utilizing its modern land imaging technology to provide clients with high resolution imaging of high potential Mississippian Chester, Osage and Meramec intervals in the center of the prolific SCOOP/STACK play fairway. Gloss Mountain 3D is complemented by TGS' extensive geologic products database in the SCOOP/STACK, comprising data from over 100,000 wells and multiple interpretive products, including Basin Temperature Modeling.

"The increased appetite from clients to fund new projects onshore North America demonstrates the value that E&P companies place in seismic as a tool to increase productivity and well results.  The addition of the Gloss Mountain 3D seismic survey, combined with our vast database of well data and interpretive products in the SCOOP/STACK play fairway, optimally positions TGS, to provide our clients with complete coverage of contiguous modern geoscientific data in this prolific area", commented Kristian Johansen, CEO for TGS.

This project is supported by industry funding.
