Data from a PGS’ MegaSurvey has revealed Tano Basin prospectivity from shelf to deep water as a supplement to ongoing coverage from Côte d’Ivoire to Nigeria.
PGS said this data package “enables regional exploration 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 MegaSurvey, adding 9 897km² of 3D and 24 632km 2D 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 Côte d’Ivoire MegaSurvey spans the western extension of the prolific Tano Basin and covers two recently spudded exploration wells “Baleine-1X” (Eni) and “Obunu-1X” (Total). The MegaSurvey 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.
PGS said the basin-wide understanding provided by the 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.
The new MegaSurvey coverage allows the entire West African transform margin to be analysed in a regional context.
PGS 3D data along the margin covers existing discoveries, farm-in opportunities, and open blocks available for licensing. A special promotional package is available that allows exploration for analogs, identification of new prospects, and detailed play analysis from shelf to deep water, along the entire margin.
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 available to be assessed.
