Overview

Our Garyville refinery is located along the Mississippi River in southeastern Louisiana between New Orleans and Baton Rouge. It has a crude oil refining capacity of 617,000 barrels per calendar day (bpcd).

The Garyville refinery is configured to process a wide variety of crude oils into gasoline, distillates, natural gas liquids and petrochemicals, heavy fuel oil, asphalt and propane. Products at the refinery are transported by pipeline, barge, transport truck, rail and ocean tanker. The refinery has access to the export market and multiple options to sell refined products. A major expansion project was completed in 2009 that increased Garyville’s crude oil refining capacity, making it one of the largest refineries in the U.S.
