TGS Starts Seismic Survey Offshore AU

TGS has commenced acquisition of a 3D multi-client seismic survey in the Outer Exmouth Plateau area. The new survey, Gnaraloo, covers 808 square miles (2,093 square kilometers) over parts of blocks WA-347-P, WA-348-P and neighboring open acreage to the north of the Mary Rose Northeast 3D multi-client survey, previously announced in December 2011. The Gnaraloo survey ties in with existing modern 3D coverage in the area. Upon completion of the Gnaraloo survey, the TGS portfolio of 3D multi-client coverage in this highly prospective area offshore Australia will exceed 5,405 square miles (14,000 square kilometers).

The seismic data is being acquired by the M/V Geo Atlantic and is expected to complete during early 2Q 2012 with final data available in 4Q 2012. The survey is supported by industry funding.
