TGS-Nopec Geophysical Co. began acquisition of a new non-exclusive 2D survey in Indonesia's Makassar Strait, Southeast Asia. The 5,200 km CM04 survey complements and infills data acquired by the company's earlier MDD99, CM01, and CM02 surveys. Industry pre-funding supports the survey.

New data will be acquired over part of the West Sulawesi Fold Belt, which was largely unknown prior to the company's work in the area.

The new dataset will enable petroleum explorers to better define the geological history of the area. The area covered by CM-04 is likely to be offered in a bid round by the Indonesian government during the second half of 2005.

The TGS-NOPEC non-exclusive seismic database in the Straits of Makassar will total in excess of 25,000 km of 2D data upon conclusion of the survey.
