Orange Basin 3D Seismic Survey

Phase Four - Gap

Leading exploration efforts in a top-tier super basin worldwide

The Orange Basin, located off the coasts of Namibia and South Africa, has become a beacon of exploratory success in recent years. Searcher is proud to be at the forefront of this region, amassing an impressive 12,500 square kilometers in Namibian waters and an additional 9,000 square kilometers in South African waters.

In collaboration with Shearwater and NAMCOR, Phase 4 of our leading exploration project in the Namibian Orange Basin has added another 2,306 square kilometers of multi-client 3D (MC3D) data to our existing 10,300 square kilometers. This latest survey took place over PEL 39, near the South African border, and connects seamlessly with our 2024 South African MC3D seismic survey. By utilising multicomponent streamers for superior de-ghosting, the imaging and AVO de-risking highlight potential world-class Graff and Venus-style plays, positioning it as a prime site for exploration discoveries.

Our extensive and detailed data acquisition in the Orange Basin delivers critical insights into the geological framework of this resource-rich area, positioning Searcher at the forefront of exploration in the region. The advanced datasets provide essential information for your exploration teams.
