SOUTH PERTH, Australia — Searcher Seismic has completed a multiclient 3D seismic acquisition campaign in the Orange Basin offshore Namibia, which has delivered deepwater discoveries for operators Shell and TotalEnergies over the past 18 months.
The campaign was a collaboration with Shearwater and NAMCOR, and it comprised two separate surveys conducted in phases.
During Phase 1, Searcher acquired 1,700 sq km of 3D data within the boundaries of Block PEL 85, which lies within the basin’s most prospective acreage. According to the company, fast-track data have provided insights into geological features and hydrocarbon prospectivity.
“We have been astonished by the quality of the Phase 1 imaging even on the early data volumes allowing us to de-risk reservoir, source and multiple traps already,” said Neil Hodgson, vice president of Geoscience.
For Phase 2, Searcher mobilized the Shearwater Empress to acquire 5,000 sq km of 3D seismic over Block PEL 3. The main aims were to image and delineate the reservoir geology of the Kudu gas field, operated by BW Energy, and other potential plays within the survey area.
The company has now acquired more than 6,700 sq km of 3D data offshore Namibia during the 2022-2023 season, which it claims is the largest multiclient 3D offering throughout the Orange Basin.
Final products should be completed by fourth-quarter 2023.
