OSLO, Norway – PGS has released data from its 900-sq km (347-sq mi) multi-azimuth broadband seismic survey over block CI-706 offshore Côte d’Ivoire.
According to the company, it provides increased resolution and sharper imaging of prolific Upper Cretaceous plays in the block.
Recently completed final depth processing has improved illumination of the block, adding a second azimuth to existing GeoStreamer data. The latest north-south acquisition, which covers the majority of the block, was processed with the underlying east-west-acquired data. The company said the combined azimuths benefit from the GeoStreamer broadband frequency bandwidth and a comprehensive depth imaging flow.
The combination of two data azimuths has resulted in increased resolution of complex faulting in the syn-transform section, to enable a greater understanding of the distribution of Albian sandstone targets hosted in tilted fault blocks.
The imaging of the prolific Upper Cretaceous play is also improved, with a clearer delineation of turbidite channel and fan complexes. Heightened imaging of the geomorphology of stratigraphic pinch-out traps can also reduce the risks associated with hydrocarbon migration and trap integrity, PGS said.
A further 7,000 sq km (2,703 sq mi) of GeoStreamer broadband data is expected to be available in July 2020.
