The latest PGS mega-survey data reveals Tano Basin prospectivity from shelf to deep water across the West African Transform Margin.
The latest PGS mega-survey data reveals Tano Basin prospectivity from shelf to deep water across the West African Transform Margin.
In partnership with PetroCi and Direction Générale des Hydrocarbures, PGS has completed phase two of the Côte d’Ivoire mega-survey, adding 9897 km2 of 3D data and 24,632 km of 2D data in the Tano Basin. Data from phases 1 and 2 have been matched, merged, and re-binned onto a common grid, to create a single, continuous 32,310 km2 volume of full-stack data in the time domain.
The latest Cote d’Ivoire mega-survey spans the western extension of the prolific Tano Basin and covers two recently spudded exploration wells ‘Baleine-1X’ (Eni) and ‘Obunu-1X’ (Total). The mega-survey is also along strike to the recent Eni ‘Eban-1X’ nearfield discovery, which is reported to have found light oil in an 80m-thick section of Cenomanian sandstones.
Numerous Upper Cretaceous turbidite channel and fan systems present in the eastern deepwater area are also revealed on the new coverage.
The new mega-survey coverage allows the entire West African transform margin to be analysed in a regional context. ‘The basin-wide understanding provided by PGS MegaSurvey seismic data allows reliable regional depositional models to be built both spatially and temporally through geological time, making it easier to identify the best potential targets for future exploration,’ said PGS.
PGS 3D data along the margin covers existing discoveries, farm-in opportunities, and open blocks available for licensing.
Five key regional horizons have been tied to wells and interpreted allowing field-scale geological understanding to be placed into a basin-wide context and open acreage opportunities to be assessed with confidence.
