PERTH, AUSTRALIA (10 March, 2010) - TGS confirmed today the continuation of its multi-client 2D seismic acquisition program in offshore Indonesia. An additional 7,300 kilometers of 2D seismic data is now being acquired in three areas along the Sundaland Margin; including offshore South Java, West Sumatra and Northwest Sumatra, Indonesia.

These new seismic surveys complement TGS' existing data library. Upon the completion of this latest program, the TGS Indonesia library will exceed 108,000 kilometers of 2D seismic; 400,000 kilometers of multi-beam bathymetric data and 1,200 core samples covering over 1 million square kilometers of Indonesia's deep-water basins. TGS has the largest geoscientific multi-client data library in Indonesia and the only multi-client data across the entire Sundaland Margin.

The project is supported by industry prefunding.
