Petroleum Geo-Services (PGS) has made available first data of the MegaSurvey targeting the extensive prospective acreage of the Ghanaian offshore area.
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.
The Ghana 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.
Exploration is now pushing into the eastern frontier areas of the Saltpond and Keta Basins, expected to contain Tertiary and Upper Cretaceous potential.
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.
PGS MegaSurvey data highlights the excellent structural and stratigraphic trapping potential in the Ghanaian offshore. The regional nature of the data allows the tectonic and basin development to be fully explored leading to a greater understanding of existing and potential petroleum systems.
The Ghana MegaSurvey now completes the PGS coverage of the West Africa Transform Margin, providing the foundation for successful exploration.
