Norwegian geophysical giant TGS has commenced the Nigeria Onshore MegaSurvey, a new regional-scale seismic project covering 28,000 square kilometres across the Onshore Niger Delta.
The project is supported by industry funding and is in partnership with the Nigerian Upstream Petroleum Regulatory Commission (NUPRC), Petrodata Management Services and Reighshore Energy Services, and will deliver merged, continuous, modern three dimensional (3D) seismic coverage across one of Nigeria’s most established hydrocarbon provinces, with final products expected to be available in the third quarter of 2026.
“The onshore Niger Delta is a mature basin with a long history of exploration and production. However, much of the existing subsurface seismic data coverage is fragmented, limiting the ability of operators to assess opportunities at a regional scale”, TGS says in a statement.
“The Nigeria Onshore MegaSurvey addresses this challenge by delivering consistent seismic data continuity, enabling operators to review existing fields, evaluate undeveloped discoveries, and progress new exploration opportunities across the basin.
“By providing a unified regional dataset, the MegaSurvey supports more efficient subsurface evaluation, improved portfolio screening, and accelerated decision-making in an area that remains critical to Nigeria’s oil and gas sector”.
