TGS Announces Two New Projects in the Norwegian Barents Sea

ASKER, NORWAY--(Marketwired - Apr 24, 2014) - TGS commences new 2D and 3D multi-client projects in the Norwegian Barents Sea. Both surveys will provide customers with high quality data prior to the closing of the 23^rd Norwegian Licensing round.

The HFCE14 is a 3,100 km² 3D multi-client survey, extending TGS' existing multi-year 3D Hoop coverage to more than 20,000 km². The survey will be acquired by the M/V GECO Eagle towing 10 streamers and will cover similar Jurassic targets as the new Wisting light oil discovery.

NBR14 is an extension of TGS long offset 2D grid in the Barents Sea, adding 6,600 km to the existing data library. The survey will cover the Eastern part of the Norwegian Barents Sea, including the newly opened area in the former disputed Norway-Russia zone. M/S Academik Shatskiy will acquire the data utilizing broadband technology.

Data processing will be performed by TGS using its Clari-Fi™ broadband processing technology and final data will be available to clients from Q4 2014.

The surveys are supported by industry funding.
