Proven Hydrocarbon Province
The Ghana MegaSurvey consists of 24 000 sq. km of 3D seismic data extending from the prolific Tano Basin in the west, through the Salt Pond Basin and into the relatively frontier Keta Basin to the east (above). The MegaSurvey covers the proven Upper Cretaceous oil play as targeted in the Jubilee and TEN fields. Multiple undrilled stacked turbidite channel and fan systems can be delineated using PGS MegaSurvey data, as shown below. Exploration is now pushing into the eastern frontier areas of the Saltpond and Keta Basins, expected to contain Tertiary and Upper Cretaceous potential. This ongoing exploration and appraisal continues to boost Ghana’s resources and the Ghanaian offshore continues to be one of West Africa’s exploration hot spots.
MegaSurvey Key to Regional Understanding
MegaSurveys are regional scale, merged post-stack datasets consisting of multiple surveys that will be rebinned to a common grid and then matched to produce a phase-balanced and uniformly-scaled contiguous regional volume. Extensive MegaSurvey coverage can be used to continue exploration for analogs of existing interests, to identify new prospects and to place field-scale geological understanding into a basin-wide context. The image below highlights the excellent structural and stratigraphic trapping potential in the Ghanaian offshore illustrated using MegaSurvey data. The regional nature of the data allows for the tectonic and basin development to be fully explored leading to a greater understanding of existing and potential petroleum systems. Covering both existing discoveries and open blocks available for licensing, analogs can be drawn and regional evaluations of existing successes and failures can be made.
Completes Coverage from Côte d’Ivoire to Nigeria
The West African Transform Margin is a large tectonically constrained area bounded by a series of major fracture zones formed during the separation of the African and American continents in the Late Jurassic to Cretaceous. Gaining a regional understanding of the complex tectonostratigraphic evolution of the area is key in understanding the basin development and prospectivity. The Ghana MegaSurvey now completes the PGS coverage of the West Africa Transform Margin, shown below, providing an excellent foundation for successful exploration.
