BluEnergies and TotalEnergies Advance Harper Basin Exploration with Seismic Reprocessing and Sea Bottom Surveys
Event summary
- BluEnergies and TotalEnergies are progressing operations in Blocks LB-26, LB-30, and LB-31 offshore Liberia.
- The work program includes reprocessing 6,167 sq kms of 3-D seismic data, with over 50% completion.
- Sea bottom surveys, including Multi-Beam Echo Sounder (MBES) and seabed geochemical sampling, commenced June 19, 2026.
- Heat flow measurements are being conducted to assess the thermal history of the Harper Basin.
The big picture
BluEnergies and TotalEnergies' collaboration in the Harper Basin aligns with the broader industry trend of major oil companies securing deepwater acreage along the West Africa Transform Margin. The focus on basin floor fan plays, proven successful in regions like Ghana and Namibia, underscores the strategic importance of this exploration initiative. The scale of the Blocks—covering approximately 8,924 square kilometers—positions BluEnergies as a key player in the region's energy sector.
