The future Tano Basin in Ivory Coast is targeted with this additional 3108 km2 of 3D seismic data targeting an open area, extending the continuous coverage of MegaSurvey data from Ivory Coast to Nigeria.
In partnership with PetroCi and the Direction Générale des Hydrocarbures, PGS expanded the Ivory Coast MegaSurvey, bringing the total coverage to 33,861 km2 in 3D and 31,743 line km in 2D. The different 3D input datasets were matched, merged and aggregated onto a common grid, resulting in a single, continuous volume of complete time domain seismic data.
The Ivory Coast MegaSurvey covers the western extension of the prolific Tano Basin and covers Eni's highly publicised Whale-1X 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 Eni's 2021 "Eban-1X" discovery, offshore Ghana, which reportedly found light oil in an 80m-thick section of Cenomanian sandstone. These discoveries highlight the significant remaining potential of the Cretaceous shelf edge play along the margin.
New coverage for open blocks CI-523, CI-525 and CI-804
MegaSurvey regional seismic allows exploration of analogues, identification of new prospects and allows detailed analysis of the play from shelf to deep water, across the margin. Five key regional horizons were linked to the well and interpreted, allowing field-scale geological understanding to be placed in a basin-scale context and open acreage opportunities to be assessed with confidence.
