Understanding Gulf of Mexico Offshore
The federal offshore Gulf of Mexico is an offshore producing province rather than an onshore sedimentary basin page. Activity ranges from shelf developments to deepwater fields in the Central and Western planning areas. Reservoirs occur in multiple Tertiary trends, including Miocene and Paleogene systems, and project timelines are generally longer than those of onshore shale wells.
Platform maintenance, hurricanes, subsea infrastructure and the timing of large field startups can move Gulf output materially from month to month. EIA publishes dedicated federal Gulf oil and marketed-gas series, so offshore production can be shown without using PADD 3 or coastal-state totals. Onshore DPR well counts and land rig measures are not applicable to this geography.
