CDI Blk 700/701 3D GeoStreamer®

High quality 3D GeoStreamer data covering the frontier offshore area of western Côte d’Ivoire
Website Map for Survey CDI_506_507_GS_MC3D_14
A number of recent discoveries encourage exploration in this underexplored basin with remarkable success derisking Late Cretaceous channel and fan systems.
Extensive prospectivity studies show signs of hydrocarbon presence within these open blocks with multiple potential targets identified within Syn-rift Aptian/Ablian structural plays and Upper Cretaceous post-rift stratigraphic plays.
Multi-sensor acquisition and PSDM processing give excellent data quality, characteristically rich in frequency content.
