TGS Begins 2D Regional Multi-Client Project Offshore Benin

TGS-NOPEC Geophysical Company (TGS) has commenced acquisition on a new 3,500-kilometer multi-client 2D seismic survey in offshore Benin.

The Benin 2D program is an extension of the 10,000 kilometers of TGS 2D that was recently acquired offshore Ghana. This 2D project is designed to help further define the extent of the petroleum system in the ultra-deep waters of Benin.

"The offshore Benin project adds to TGS' extensive coverage in the Gulf of Guinea and continues to clarify the regional geologic picture in this important and developing area of offshore West Africa," said David Hicks, VP of Africa, Middle East and Asia Pacific for TGS.

The MV Northern Genesis is acquiring the data.
