A Clearer Image with CI-706 MAZ
Depth processing of the CI-706 multi-azimuth survey was completed in February 2020, comprising over 900 sq. km of GeoStreamer 3D data. New north-south acquisition over most of the block was processed with underlying data acquired east-west. GeoStreamer broadband technology maximizes the frequency bandwidth of the data and this, together with a comprehensive depth imaging flow, leads to superior illumination.
Combining the two data azimuths results in increased resolution of complex faulting in the syn-transform section, providing explorers with 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 7 000 sq. km of GeoStreamer broadband data will be available in the PGS data library from July 2020.
Regional Context with CDI MegaSurvey
In partnership with PetroCi and Direction Générale des Hydrocarbures, PGS has completed phase one of the CDI MegaSurvey. Phase two, focusing on the Eastern Côte d’Ivoire Basin will be available from mid-2020. The MegaSurvey is made up of over 23 000 sq. km of 3D and 12 000 line km of 2D data. GeoStreamer and conventional data are matched, merged and re-binned onto a common grid resulting in a single, continuous volume of full-stack data in the time domain.
The MegaSurvey allows the entire Ivorian Transform Margin to be analyzed in a regional context. The contiguous data covers both existing discoveries and open blocks available for licensing and enables exploration for analogs, the identification of new prospects, and detailed play analysis across the basin.
Five key regional horizons have been tied to wells and interpreted across the dataset, allowing field-scale geological understanding to be placed into a basin-wide context and open acreage opportunities to be assessed with confidence.
Cretaceous Potential Revealed in Open Acreage
RMS amplitudes extracted through an interval of Cretaceous turbidite deposits clearly delineate the drilled channel systems to the east of the MegaSurvey and highlight that sediments were sourced from the west. The interpretation of key Upper Cretaceous horizons as part of the MegaSurvey package reveals well-developed submarine fans hinting at reservoir potential over open blocks.
The basin-wide understanding provided by MegaSurvey seismic data allows for reliable regional depositional models to be built both spatially and temporally through geological time, allowing for the best potential targets to be identified for future exploration.
