Two new seismic surveys in Russia

28 July 2005OSE

Naersnes, Norway and Houston, Texas (28 July, 2005) - Russian geophysical companies, partners of TGS-NOPEC Geophysical Company (TGS), have initiated two new seismic programs offshore Russia. In the Sea of Okhotsk near the Sakhalin Island, Partner Dalmorneftegeofizika (DMNG) will acquire 8,000 kilometers of multi-client 2D seismic data. The new program will infill the pre-existing seismic grid in the region and extend the program into the Sakhalin 6 area for the first time. In the Barents Sea, Partner New Geoprojects will acquire 7,000 kilometers of multi-client 2D seismic data.

TGS is pleased that the plan of building up a completely new regional 2D seismic grid in the Russian Barents Sea is materializing and that TGS is chosen as partner to offer these data to market. Many geoscientists believe that the Barents Sea is one of the most prospective petroleum provinces in the world.

Final data on both surveys is expected to be available by year end.
