ASKER, NORWAY (5 July 2011) - TGS will commence acquisition of a new 3D multi-client survey which covers 1,100 km2 over the Magnus Basin, including the southwest to northeast striking "End of the World" fault.  TGS will also reprocess approximately 6,500 km2 of 3D seismic data in the same area to build a combined project of 7,600 km2.  

The new seismic data will be acquired by M/V Geo Pacific towing 8 x 6,000 m streamers and be completed in Q3 2011.  Data processing from the new acquisition and reprocessing will be performed by TGS and available to clients from late Q1 2012.  The survey is supported by industry funding.
