TGS expands 3D multi-client seismic data library in Sierra Leone

HOUSTON (20 July 2011) - TGS will commence acquisition of multi-client 3D seismic data in offshore Sierra Leone later this month.  This survey marks over ten years of investment for TGS in the West African region and will add 2,535 km2 to the existing TGS data library.  The new 3D seismic will provide important data for continued exploration on the Sierra Leone segment of the West Africa Transform Margin, where recent discoveries have established that a working hydrocarbon system exists.

The M/V GeoCarribean will acquire the 2011 survey.  Data processing will be performed by TGS and available to clients in Q1 2012. 

The survey is supported by industry funding.
