TGS-NOPEC to Acquire New 2D in the Sea of Okhotsk

TGS-NOPEC Geophysical Company, in co-operation with Dalmorneftegeophysica (DMNG), will acquire a new multi-client 2D seismic survey north and east of Sakhalin Island in the Sea of Okhotsk.

The program is strongly supported by industry pre-funding and acquisition will start in late June or early July. Final data will be available for delivery during Q4 in 2004.

With a total length of the program in 9100 kilometers, the project is designed to infill the Company's 1998 survey and to examine deeper basins immediately to the east of the producing fields offshore Sakhalin Island. The province is estimated to be among the most prolific hydrocarbon provinces worldwide.

TGS-NOPEC is currently reprocessing its 9,700-kilometer 1998 Sea of Okhotsk survey utilizing current technology including pre-stack time migration to improve imaging and resolution. This reprocessed data set, in combination with the new program will constitute the most modern and complete multi-client seismic coverage offshore Sakhalin Island.

DMNG's M/V Zephyr 1 will acquire the program with a 6000 meter streamer.
