The Gulf of Mexico Outer Continental Shelf (OCS) continues to be the most intensely developed offshore oil-and-gas producing region in the world. With the development od technology, exploration, development, and produciton are being extended to include areas off the coast of Southwest Florida and deepwater areas near the Mississippi River Delta. Development in both areas requires careful analyses of local considerations. The hydrocarbon potential of the region, while not well established in the frontier portions, generally remains favorable. A total of 482 fields have been discovered to date in the federally regulated part of the Gulf of Mexico. Reserve estimates have been made for the 435 producing fields in that region. Through December 31, 1980, those fields have produced 5.0 billion barrels of oil and condensate, and 48.7 trillion cubic feet of gas. Remaining recoverable reserves are 3.1 billion barrels of oil and 40.2 trillion cubic feet of gas. Estimates of undiscovered recoverable reserves for the Gulf of Mexico are 6.6 billion barrels of oil and 71.9 trillion cubic feet of gas. Since enactment of the Outer Continental Shelf Lands ACt in1953, there have been 42 oil and gas lease sales in the Gulf of Mexico. An average of three lease sales per year are scheduled through 1986. Since 1953, the Bureau of Land Management (BLM) has leased 3,119 tracts in the Gulf of Mexico; 1,825 lease are currently active. The distribution of leased tracts exhibits a regionwide pattern as shown by lease sales A62, 62, A66, and 66. Proposed Lease Sales 67, 69, 72, and 74 will probably continue that pattern. Tracts off the coast of southwest Florida in the Charlotte Harbor, Howell Hook, and Pulley Ridge areas will be offered in upcoming sales. Operations on tracts in deepwater areas slated for future sales may require additional technology. Exploration, development, and production in the Gulf of Mexico Region are continuing at a rapid pace throughout the Gulf of Mexico. Between January 1, 1980, and April 15, 1981, 197 initial plans of exploration and 165 supplemental plans of exploration were submitted to the U.S. Geological Survey (USGS). Duirng the same period, 107 initial and 131 supplemental plans of development/exploration were submitted to the USGS, As of May 1981, there were 121 offshore mobile drilling nunits in the Gulf of Mexico. Pipelines continue to be the preferred mode of transport for Gulf of Mexico OCS oil and gas production. Pipeline additions to the existing network avergae 69 miles (111 km) per month. At any given time, numerous pipeline projects are under way in the Gulf of Mexico. To supplement OCS oil and gas production several deepwater port projects, designed to handle imported crude oil, are being planned or constructed in the region, The process of transportstion planning in the Gulf of Mexico is done by industry and government through BLM's Intergovernmental Planning Program and its Regional Technical Working Group (RTWG). The RTWG has completed the First Edition Gulf of Mexico Regional Transportation Management Plan. The nearshore and onshore facilities in the Gulf of Mexico service both the domestic onshore and offshore iol and gas industry as well as the global market. Most of the major centers along the Gulf Coast, including Houston, Corpus Christi, Galveston, Beaumont, Port Author, and Freeport, Texas; New Orleans, Lake Charles, Lafayette, Baton Rouge, Morgan City, and Houma, Louisiana; Pascagoula, Mississippi, Mobile, Alabama; and Port Manatee, Florida, have ties to the offshore industry. A wide array of services and support industries, ranging from small independant vendors to major internaitonal manufacturing contractors, can be found within the region. Profiles of selected centers reveal typical industries and patterns of activity that are characteristic throughout the Gulf Coast region.
