Refinery, Frontier Refining & Marketing

The El Dorado Refinery is one of the largest refineries in the Plains States and the Rocky Mountain region with a crude oil capacity of
135,000 barrels per day.
The El Dorado Refinery can select from many different types of crude oil because of its direct access to the Cushing, Oklahoma hub, which is connected by pipelines to the Gulf Coast and to Canada. This access, combined with the El Dorado Refinery’s complexity, gives it the flexibility to refine a wide variety of crude oils. The El Dorado Refinery also has a coking unit, which allows the refinery to process a large percentage of heavy, discounted crudes.
We market El Dorado’s refined products primarily in the eastern slope of the Rocky Mountain region, which encompasses eastern Colorado (including the Denver metropolitan area) and eastern Wyoming, and throughout the Plains States. The El Dorado Refinery's product mix includes gasoline (55%), diesel and jet fuel (34%) and asphalt, chemicals and other refined petroleum products (11%).
