Gulf of Mexico Oil & Gas Production
The federal waters of the Gulf of Mexico are the largest offshore oil-producing region in the United States and the only offshore one of real scale. Output comes overwhelmingly from deepwater platforms run by a small group of majors and specialist operators, and it is the part of US supply most exposed to hurricanes.
Key Figures
| Measure | Value | As of / source |
|---|---|---|
| Federal offshore Gulf crude production | 2,043 kb/d in July 2026 (14.6% of US output, +6.1% on a year earlier) | EIA monthly production, federal offshore |
| Name | Called the Gulf of America in US federal usage since 2025; EIA series are still labelled Gulf of Mexico | US federal government |
| Regulators | Bureau of Ocean Energy Management (leasing) and Bureau of Safety and Environmental Enforcement (safety) | |
| Character | Mostly deepwater platforms and subsea tiebacks, with long field lives and large per-well output | BOEM; BSEE |

The Offshore Oil Region
Why it matters
- Offshore Gulf fields feed Gulf Coast refineries by pipeline and are among the highest-volume, lowest-decline fields in the country compared with shale wells.
- New output comes from a steady flow of subsea tiebacks to existing platforms and a few new standalone developments, which is slower and lumpier than shale drilling.
- Federal lease sales set the pipeline of future projects and are a policy lever for each administration.
Hurricane risk
- Storms can shut in a large share of Gulf production and evacuate platforms for days; see hurricane season and oil prices.
- Onshore Gulf Coast refineries and ports are exposed to the same storms, so a hurricane can move both crude and product prices, as the crack spread shows.
- US-wide production context: US oil production.

Companies in this site's directory with material producing positions in the Gulf of Mexico include BP, Chevron, Shell, Murphy Oil, Occidental, Talos Energy (some hold non-operated interests). Ownership and the other basins each one works are in the producer table above and in the oil company directory.
How much oil does the Gulf of Mexico produce?
Federal offshore Gulf of Mexico crude production was about 2,043 thousand barrels a day in July 2026 according to EIA, roughly 14.6% of US crude output. It is much larger than the Pacific offshore and is the only offshore region that matters at national scale.
Why is Gulf of Mexico oil important to refiners?
Offshore Gulf crude is delivered by pipeline to Louisiana and Texas Gulf Coast refineries, which are the largest concentration of US refining capacity. It is a mix of sweet and medium-sour grades, which those refineries are built to process.
