ASKER, NORWAY (16 January 2018) - TGS announces three new onshore seismic projects; Sanderson, West Hackberry and Dawson in prolific North American basins.

The West Hackberry 3D multi-client seismic survey is located north of TGS` Loyal 3D Complex in the Anadarko Basin. This new project will encompass 777 km2 predominantly in Garfield County in the state of Oklahoma. The Hackberry Complex will target a high potential area in the core of the prolific Mississippian Chester and Meramec intervals of the SCOOP/STACK play fairway.

The Sanderson 3D multi-client seismic survey is TGS` third seismic project in the Permian Basin and is located along the eastern flank of the Delaware Basin to the east of TGS` West Lindsey 3D. This new project will encompass 464 km2 predominantly in Pecos County, Texas and provide modern, high resolution 3D seismic data to an area that is seeing high interest from E&P companies. Strong potential exists in multiple zones including the Artesia Group on the shelf, the Delaware sands and the prolific Wolfcamp, as well as the historic deep productive trends in the Siluro-Devonian and Ordovician Ellenburger.

The Dawson 3D multi-client seismic survey is located in the province of British Columbia, Canada and provides a complimentary addition to our existing footprint in this region. This new project will encompass approximately 70 km2 providing enhanced imaging solution of the Montney shale formation.

Permitting on all three surveys has already commenced and data acquisition is expected to begin within first half of 2018. Preliminary data will be available in Q2 and Q3 2018. The data will be processed by TGS utilizing its modern land imaging technology.

"With support from our clients, TGS continues to strengthen our onshore position. I am pleased to announce such a diverse portfolio of new seismic projects in key shale basins of North America, such as the Permian Basin, SCOOP/STACK and the Montney. With our growing onshore seismic library, combined with our vast database of well data and interpretive products, TGS is uniquely positioned to help our customers develop the best data driven subsurface models to aid their exploration efforts," commented Kristian Johansen, CEO for TGS.

All three projects are supported by industry funding.
