TGS has commenced an extension to the offshore Angola 3D multi-client survey. The extension, covering 4,064 km2 over blocks 36 and 37, will add to the original survey of 12,500 km2 which has completed acquisition.

"We are very pleased to continue our relationship with Sonangol and to support oil and gas exploration in the Republic of Angola," commented Stein Ove Isaksen, Senior VP Eastern Hemisphere for TGS. "Angola's conjugate margin pre-salt basins, similar to hydrocarbon rich basins offshore Brazil, provide exciting new opportunities in petroleum exploration."

The seismic data is being acquired by the M/V Geco Eagle. Data processing will be performed by TGS and preliminary data will be available to clients from Q4 2013.

The survey is supported by industry funding.
