TGS Completes Sierra Leone Offshore Seismic Data Enhancement Project
Norwegian energy data and intelligence company TGS has completed a major multi-client reprocessing project that significantly enhances seismic data for hydrocarbon potential in acreage off the coast of Sierra Leone. The Sierra Leone Fusion 3D multi-client reprocessing project involved full reprocessing from field tapes of a 7,476 square kilometer area through a comprehensive pre-stack depth migration sequence.
The project utilized advanced machine learning-based denoise and deghosting, adaptive demultiple and advanced depth imaging workflows, including DM-FWI, to deliver clearer imaging of Upper Cretaceous plays in Sierra Leone’s high-potential basin. TGS merged multiple surveys it acquired between 2008 and 2014, placing strong emphasis on preserving AVO fidelity throughout the data to enable companies to perform advanced reservoir characterization workflows and assess AVO plays with greater confidence.
David Hajovsky, Executive Vice President of Multi-Client at TGS, noted that Sierra Leone sits within a proven yet underexplored segment of the West African Atlantic Margin, where access to consistent, high-quality seismic data is critical for informed exploration decisions. The Fusion 3D project strengthens the regional subsurface framework, enabling companies to place individual prospects into a broader geological context and evaluate opportunities with greater confidence as interest in the basin continues to build.
With the addition of significantly improved seismic data in the country’s offshore basins, TGS expands its portfolio of multi-client seismic data in Africa, furthering its commitment to advancing resource development and hydrocarbon exploration across the continent. The completion follows shortly after the firm opened an imaging center in Malaysia for multi-client projects throughout the Asia-Pacific region.
