PGS releases new seismic data from offshore Ivory Coast
Published by Nicholas Woodroof,
This new 900 km2 multi-azimuth broadband seismic survey from PGS provides increased resolution and sharper imaging of prolific Upper Cretaceous plays in Ivory Coast block CI-706.
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 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.
A further 7000 km2 of GeoStreamer broadband data will be available in July 2020.
