Gulf Coast Refining Capacity

Refineries in the Gulf Coast area surrounding Houston make up the largest refining center in the United States.
Published on 4/14/21
Gulf Coast Refining Capacity

The majority of the refineries in the state of Texas are clustered near major sea ports along the Gulf Coast, predominately in the Houston area. The 10 refineries in the Houston metro process 2.6 million barrels of crude oil per calendar day – 45.4 percent of the state’s total production and 14.3 percent of the nation’s production. The entire Gulf Coast Region – including Corpus Christi, Port Arthur and Beaumont – accounts for 87.3 percent of the state’s total production and more than a quarter of production in the United States.

These coastal refineries have access to local Texas production, foreign imports, and oil produced offshore in the Gulf of Mexico, as well as the U.S. government’s Strategic Petroleum Reserve, which operates two large storage facilities in Texas.
