TGS builds Liberia data bank
TGS remains active in seismic surveying off West Africa, according to the company’s review of its recent progress.
ASKER, Norway -- TGS remains active in seismic surveying off West Africa, according to the company’s review of its recent progress.
Late last year, TGS resumed acquisition of 3D data in Liberian offshore block 14 using the BGP Pioneer and completed its program in January. The company has acquired a total of 11,000 sq km (4,247 sq mi) of 3D data off Liberia and more than 14,000 sq km (5,405 sq mi) over the Sierra Leone/Liberia margin.
In the same region, the company recently completed a 1,480-km (920-mi) contract survey off Guinea-Bissau and a 1,200-km (745-mi) multi-client survey offshore Ghana.
It also has concluded data processing of its 6,000-sq km (2,316-sq mi), 3D multi-client survey over Liberian blocks 15-17, and a 13,500-km (8,388-mi) 2D multi-client regional survey over the waters between Ghana and Benin.
In other frontier areas, TGS has completed final processing and client delivery of around 10,000 km (6,214 mi) of 2D multi-client data along Indonesia’s West Sumatra and Sundaland margin.
The Bergen Surveyor has concluded a 15,000-sq km (5,791-sq mi), 2D multi-client survey in Baffin Bay off Greenland. This has increased the company’s 2D data bank over the area to more than 60,000 km (37,282 mi). Processed data should be available shortly in preparation for the Baffin Bay licensing round scheduled to close in May.
Towards the end of 2009, TGS started the final phase of its Southern Basin Project offshore Brazil. The final 25,000-km (15,534-mi) phase of re-processing should be completed next month, allowing TGS to provide modern depth-imaged data across the entire southern Brazil region from the Espirito Santo through Santos basins.
