Offshore staff
OSLO, Norway — TGS is teaming up with the National Oil Company of Liberia (NOCAL) to reprocess 2D and 3D seismic data covering two prospective offshore basins.
The project involves integrating legacy datasets to create a unified velocity model in depth, using imaging algorithms to deliver the final migrated seismic data.
The reprocessed products should support exploration, TGS added, by providing continuous seismic attributes of higher confidence at target levels throughout the margin.
David Hajovsky, eceutive vice president of Global Multi-client at TGS, said the new data would be “essential in promoting future licensing rounds offshore Liberia under a direct negotiation approach. It also allows E&P companies to further evaluate exploration opportunities in an underexplored but proven petroleum system adjacent to prolific hydrocarbon provinces."
Recently the company finished the first phase of reprocessing about 12,097 km of 2D legacy offshore seismic data to improve subsurface clarity, and the results are available for licensing.
The second phase, now underway, will reprocess an additional 12,675 line km over the Liberia and Harper basins, bringing the total to more than 24,700 km. In adition, TGS plans to reprocess 15,616 sq km of legacy 3D seismic data in the Liberia basin.
