PGS releases GeoStreamer 3D for Côte d’Ivoire
Marine geophysical firm PGS released a new 900 sq. km multi-azimuth GeoStreamer 3D seismic survey, providing increased resolution and sharper imaging of prolific Upper Cretaceous plays in Côte d'Ivoire 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.
PGS provides seismic images and 3D data describing the subsurface beneath the ocean floor that oil companies rely on to find oil and gas reserves worldwide. A further 7 000 sq. km of GeoStreamer broadband data will be available in July 2020.
