PGS Releases Additional 3D Data for West Africa Transform Margin and Côte d’Ivoire

Côte d’Ivoire’s prospective Tano Basin is targeted with this additional 3108  sq. km of 3D seismic data targets open acreage, which expands continuous MegaSurvey data coverage from Côte d’Ivoire to Nigeria.

In partnership with PetroCi and Direction Générale des Hydrocarbures, PGS has expanded the Côte d’Ivoire MegaSurvey, bringing the total coverage to 33 861 sq. km of 3D and 31 743 line-km of 2D. The various 3D input datasets have been matched, merged and re-binned onto a common grid resulting in a single, continuous volume of full-stack seismic data in the time domain.  

Additional CDI MegaSurvey data is highlighted in orange

The Cote d’Ivoire MegaSurvey spans the western extension of the prolific Tano Basin and covers the high-profile Baleine-1X (Eni) discovery with preliminary resource estimates of up to 2.0 billion barrels of oil in place and up to 2.4 trillion cubic feet (TCF) of associated gas in two main Cretaceous reservoir levels. The dataset also occurs along-strike of the 2021 Eni “Eban-1X” discovery, offshore Ghana which is reported to have found light oil in an 80m thick section of Cenomanian sandstones. These discoveries highlight the significant remaining potential of Cretaceous shelf edge play along the margin.  

New Coverage of Open Blocks CI-523, CI-525 and CI-804

MegaSurvey regional seismic enables exploration for analogs, the identification of new prospects, and allows detailed play analysis from shelf to deep water, along the entire margin. Five key regional horizons have been tied to well and interpreted allowing field-scale geological understanding to be placed into a basin-wide context and open acreage opportunities to be assessed with confidence.
