Oligocene-Pliocene Deepwater Basins – A Review of Geology, Reserves and Economics

B033 OLIGOCENE-PLIOCENE DEEPWATER BASINS: A REVIEW OF GEOLOGY RESERVES AND ECONOMICS Abstract Introduction. Important discoveries have been made in deep marine settings during the last ten years. Although spectacular giant fields were found deepwater reserves with a total of some 77 billion barrels of oil equivalent (Bboe) only represent 8% of all offshore reserves. Deepwater is defined as water depths beyond 500 meters in this paper. 1 A large part of the deepwater reserves are located in reservoirs of Oligocene to Pliocene age. To better predict future potential in deep marine reservoirs a study was undertaken to analyse basins worldwide
