TGS has commenced acquisition of a 3D multi-client seismic survey in the Outer Exmouth Plateau area.

The new survey, Gnaraloo, covers 2,093 km2 over parts of blocks WA-347-P, WA-348-P and neighbouring open acreage to the north of the Mary Rose Northeast 3D multi-client survey.

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 the prospective area offshore Australia will exceed 14,000 km2.

The seismic data is being acquired by the M/V Geo Atlantic and is expected to complete during the early second quarter of 2012 with final data available in the fourth quarter.
