PGS releases Côte d’Ivoire GeoStreamer data

  • Exploration & Production

Marine geophysical firm PGS has released new multi-azimuth GeoStreamer 3D for Côte d’Ivoire.

This 900-square-kilometre survey should provide increased resolution and sharper imaging of 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.

Processing of the latest north-south acquisition, which covers the majority of the block, combines with the underlying east-west-acquired data.

The combined azimuths benefit from the GeoStreamer broadband frequency bandwidth and depth imaging flow, PGS explains.

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 Upper Cretaceous play has 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.

The PGS data library offers six 3D GeoStreamer surveys and over 12,000 line kilometres of 2D data for Côte d’Ivoire.

A further 7,000 square kilometres of GeoStreamer broadband data will be available in July 2020.

No wells have been drilled in deepwater Côte d’Ivoire.

However, with modern regional datasets available, the complex sediment provenance is becoming more understood.
