The 11,425 sq km of data will support future exploration in the basin.
Existing 2D data and adjacent 3D data show the potential for reservoir depositional fairways overlying a source interval contemporaneous with the Guyana basin petroleum system to the northwest.
Basin model studies suggest a mature, extensive early Cretaceous petroleum system supported by the Zaedyus discovery nearby off French Guiana and the Narina and Venus finds on the conjugate margins of Liberia and Sierra Leone in West Africa.
Kristian Johansen, CEO of TGS, said the new survey would “be instrumental in enabling exploration companies to have a robust subsurface understanding in advance of future Permanent Offer rounds”.
Sophie Zurquiyah, CEO of CGG, added, “Our geoscientists will apply their deep regional insight and cutting-edge imaging technologies such as time-lag FWI and least-squares migration to provide the high-resolution, high-fidelity data and images necessary to better understand this frontier basin.”
Early PSDM products will be made available during fourth-quarter 2023, followed by the final products from third-quarter 2024.
