Report summary

The Gabon Basin is bordered by the Rio Muni Basin in the north and the Lower Congo basin to the south. It comprises the vast majority of Gabon’s licensed acreage, extending from the ultra-deepwater in the west, across the continental shelf and coast to the onshore jungle interior. The shelf and onshore areas of the basin are considered relatively mature. Several exploration opportunities remain open. Onshore activity has focused on the Cretaceous pre-salt horizons, whilst offshore activity has been primarily focused on post-salt reservoirs. However, deepwater drilling in the post-salt has yielded few returns, and future activity is expected to focus on the pre-salt: Total's Diaman discovery in 2013 proved the existence of a working hydrocarbon system, which was confirmed by Shell's Leopard gas field discovery in 2014. Value will only be created from such gas finds when a viable gas monetisation scheme is developed, be it a domestic market or via LNG exports.
