Our Refineries

We operate ten refineries in the western United States with a combined capacity of approximately 1.2 million barrels per day.

Powered by the deep engineering expertise of our workforce, these highly advanced facilities refine domestic and foreign crude oils into transportation fuels and other petroleum products that help drive the markets we serve.

At our refineries – and everywhere we do business – the health and safety of our employees, customers and communities is our number one priority and an integral part of our culture. We continually evaluate and invest in technologies and systems to support safe, reliable and clean operations.


Our refineries are supplied by domestic feedstocks, which includes sources in Alaska, California, Colorado, New Mexico, North Dakota, Texas, Utah and Wyoming, and from foreign feedstocks that include Canada, South America, West Africa and other foreign crudes.


Petroleum products refined at our facilities include: CARB and conventional gasoline, CARB and conventional diesel fuels, jet fuel, heavy fuel oils, liquefied petroleum gas, fuel gases, asphalt, propane, propylene, petroleum coke and calcined coke.
