ASKER, NORWAY--(Marketwired - Dec 9, 2013) - TGS has commenced acquisition of a 3D multi-client seismic survey covering 2,022 km² offshore Benin.

"The BR-13 survey will be TGS' second 3D survey in Benin," commented Stein Ove Isaksen, Senior Vice President Eastern Hemisphere for TGS. "The 3D data will build upon current subsurface knowledge and provide improved imaging of deep Cretaceous and Tertiary strata. Interpretation of this data will lead to better delineation of oil and gas prospects over the acreage surveyed as well as a greater understanding of adjacent areas."

The seismic data is being acquired by the BGP Prospector, with a 10 streamer configuration. Data processing will be performed by TGS using its proprietary seismic multiple elimination processing technology, TAME™. Final data will be available to clients from Q3 2014.

The survey is supported by industry funding.
