Exploration and discoveries, 1947-1989: An historical perspective. Gulf of Mexico OCS

Technical Report ·
OSTI ID:6865026
Original recoverable proved reserves of hydrocarbons in the 739 proved fields discovered through 1989 on the Gulf of Mexico Outer Continental Shelf (OCS) are estimated to be 10.9 billion barrels of oil (BBO) and 129.1 trillion cubic feet of natural gas (Tcfg); 57 of these fields have been abandoned. Remaining proved reserves recoverable from the 682 active proved fields have been estimated to be 3.03 BBO and 40.2 Tcfg. An additional 114 active fields have not been sufficiently developed to warrant conseration as proved. The Gulf of Mexico OCS is primarily a gas province. Cumulative production through 1989 was 7.8 BBO and 89 Tcfg. On an energy-equivalent basis the production equates to nearly 67% gas. In recent years the area has contributed about 10 percent of the domestic oil production and 22 percent of the gas. Thus, future discoveries and production from the region will have a significant impact on the Nation's oil and gas supply. Exploration and subsequent development activities have gradually progressed seaward into deeper Gulf waters. Average field size has steadily decreased over time.
