ASKER, NORWAY (24 May 2011) - TGS commences the acquisition of multi-client 3D seismic data in the Hoop Fault Complex area of the Barents Sea.  This survey is an extension of the previously announced Hoop Fault Complex survey and will add 1,800 km2 to the existing data in the area.  Approximately 500 km2 of the survey are infill in the Northern area of the 2009 survey and the remaining 1,300 km2 are an extension to the east of the 2009 survey area.  TGS is very pleased with the historical client response to the coverage in this new exploration province.  Blocks have been awarded in the survey area during the last two rounds and with the 2011 acquisition, TGS will be able to provide extended coverage for future rounds.

The M/V Polar Duke towing 10 x 6,000 m streamers with 75 m separation will acquire the 2011 survey.  Data processing will be performed by TGS and will be available to clients in Q4 2011.  The survey is supported by industry funding.
