TGS has acquired a 3D multi-client survey offshore Sierra Leone. The survey, Sierra Leone Block 4A Extension, will add 1,000 km2 of new 3D data to the existing 6,268 km2 of 3D data library in Sierra Leone.

"This survey extends our current data coverage in an important and prospective area. TGS has been active in acquiring data over the West Africa Transform Margin for the past decade and we are pleased with the level of customer support to continue our investment in this region," commented Stein Ove Isaksen, Senior VP Eastern Hemisphere for TGS.

TGS is chartering the 12 streamer Polarcus Alima for this survey. Data processing will be performed by TGS and will be available to clients in Q1 2015.

The survey is supported by industry funding.
