Orange Basin 3D Seismic Survey

Phase One - Bridge

Advancing exploration in one of the most exciting super basins in the world.

The Orange Basin has garnered significant attention due to its high exploration potential, and Searcher is thrilled to be at the forefront of this exciting region. Phase 1 of our Namibian Orange Basin Multi-Client 3D Seismic Survey marks the beginning of a series of five projects aimed at unlocking the basin’s hydrocarbon resources.

In partnership with Shearwater and NAMCOR, Phase 1 encompassed 1,700 square kilometers of multi-client 3D seismic data across PEL 3. The data, processed to PDSM, has unveiled critical insights into the block’s hydrocarbon potential, dramatically lowering risk and uncertainty.

The quality of the imaging far exceeded our expectations, enabling us to effectively de-risk reservoirs, sources, and traps. This comprehensive dataset offers valuable information that enhances our understanding of the geological framework and can be used to inform future exploration strategies.

This dataset kick started Searcher’s ground-breaking exploration initiative in the Orange Basin, with a number of further phases expanding the data’s reach across such an exciting basin.
