CAPE TOWN, South Africa – Fugro has completed a survey for Anadarko over exploration acreage in the Orange basin offshore South Africa.

Anadarko is operating the first exploration period over frontier blocks 5/6 and block 7, in partnership with PetroSA.

Fugro’s survey involved acquisition of multi-beam echo sounder (MBES) data from theMV Fugro Gauss, and onboard seep mapping interpretation. The program is part of a greater seafloor geochemical exploration survey designed by Anadarko and its partner.

The nearly 56,000-sq km (21,622-sq mi) MBES survey provided bathymetry and backscatter MBES data for identification of natural hydrocarbon seepage at the seafloor.

Fugro geoscientists onboard the vessel performed mapping of potential seeps, interpretation of the surficial sedimentary geology, structural geology and shallow fluid migration systems, and reported the acquired MBES data.

Helle Els, commercial manager of Fugro Survey Africa, said: “Seep hunting requires both MBES bathymetry and MBES backscatter data to be collected and processed in real-time during the survey. Our geologists onboard evaluate the data to determine potential seep targets and weight them for a later geochemical coring survey.”
