Spectra Energy has started a new 2D multi-client seismic survey offshore Namibia in partnership with CGGVeritas and the National Petroleum Corporation of Namibia. The programme involves the acquisition of 7,000km of long offset data that covers held and open blocks in the Orange Basin.

Spectrum said a good level of prefunding was obtained from companies to provide support for the programme.

SeaBird Exploration, a provider of marine 2D and 3D seismic data solutions, will acquire the seismic data with its Northern Explorer vessel. The data will then be processed through full pre-stack time migration and include angle stacks and AVO products.

Spectrum, due to the frontier nature of the area, will also offer a fast model, pre-stack depth migration sequence for the project. Final deliverables will be processed by June 2012.

Offshore Namibia is considered highly unexplored, with only 15 wells drilled so far in an area covering more than 500,000km2. Seven of the wells were drilled at the Kudu gas field, which was discovered by the country’s first offshore exploration well in 1973.

Over 20,000km of high-quality 2D multi-client data from offshore Namibia is also available through Spectrum in eight individual surveys. Each survey was designed and acquired to target key structures within the offshore area.
