TGS, a global provider of energy data and intelligence, today announced an agreement with the National Oil Company of Liberia ("NOCAL") to reprocess over 5,100 square kilometers of 3D seismic data over Blocks 8 & 9 in the offshore Liberia basin.

The survey will be processed using a Pre-Stack Depth Migration (PSDM) workflow to enable optimal imaging of the main targets in the Cretaceous reservoirs to reveal the latest insights into the prospectivity of the Liberia Basin.

Since June 2021, the Liberia Petroleum Regulatory Authority (LPRA), in cooperation with NOCAL, has invited direct exploration licensing negotiations for all offshore blocks over the Harper and Liberia basins. Thirty-three blocks are available with a maximum block size of 3,500 square km.

EVP Eastern Hemisphere at TGS, Will Ashby, commented, "TGS has been active in acquiring data over the West Africa Transform margin for the past two decades, and this update of a key 3D survey demonstrates TGS' ongoing commitment to exploration success in the country. Offshore Liberia offers significant hydrocarbon potential and we are proud of our long and successful partnership with Liberia."

The survey is supported by industry funding, with processing starting this month and final deliverables expected in Q2 2023.
