French Guiana Guyana exploration basin

Report summary
The Guyana Basin is a well-developed half-graben, passive margin basin. It spans French Guiana, Guyana and Suriname, extending from the coastal plain to ultra-deep waters. The basin shares many geological similarities with emerging hydrocarbon plays on the Atlantic Margin of West Africa, including offshore Ghana, where the giant Jubilee discovery was made. The Liza discovery offshore Guyana is drawing explorers to neighbouring countries to the west of French Guiana. However, the poor appraisal results of the deepwater Zaedyus discovery, coupled with other exploration disappointments here, throws doubt on the prospectivity of this portion of the basin. There are no announced exploration plans and future drilling in the basin appears bleak at least in the near term.
