TGS builds arctic region seismic data bank

Offshore staff

ASKER, Norway – TGS (OSLO:TGS) has completed a two-year 2D seismic acquisition campaign in the Labrador Sea offshore eastern Canada.

The program was performed as a joint venture with PGS, which acquired 22,118 km (13,743 mi) of data.

The seismic vessel has since started a 2D seismic program in the Flemish Pass-Orphan basin area, offshore Newfoundland. This is expected to total 20,000 km (12,427 mi) and will take two seasons to complete.

Offshore northeast Greenland, TGS has begun a new 3,000-km (1,864-mi) 2D program in partnership with Fugro. Additionally, the company started work on a 7,300-km (4,536-mi) 2D seismic survey in the Laptev and East Siberian seas of the Russian Arctic, with the program due to finish by year-end.

This summer, TGS finished acquisition of a 4,080-sq km (1,575-sq mi) EOTW 3D survey in the northern North Sea, completing a data set that is now 10,000 sq km (3,861 sq mi) in size in what the company describes as a high-potential play.

TGS has also completed acquisition of a 3,300-sq km (1,274-sq mi) EB12 survey in the Erlend basin of the northern North Sea shelf. Afterwards, the company turned its attention to the 1,520-sq km (589 sq mi) Erlend West Survey in Quads 208 and 217 of the Faroe Shetlands basin, which has now concluded.

Elsewhere, TGS continued data acquisition on a 12,500-sq km (4,826-sq mi) 3D survey offshore Angola, designed to image prospective deepwater presalt blocks thought to be geologically analogous to hydrocarbon basins offshore Brazil.

This summer, in partnership with Dolphin Geophysical, the company started an 11,250-km (6,990-mi) 2D seismic campaign offshore Mauritania, the second phase of the NWAAM 2D multi-client program. Acquisition should be concluded shortly.

Finally, TGS has completed its fourth multi-client 3D survey in the Exmouth Plateau offshore northwest Australia, the 2,536-sq km (979-sq mi) Honeycombs program.
