Refinery, Frontier Refining & Marketing

Our Cheyenne Refinery has a permitted crude oil capacity of 52,000 barrels per day. Crude oil is purchased from local producers and also imported via the Express Pipeline from Canada.
The Cheyenne Refinery has a coking unit, which allows the refinery to process extensive amounts of heavy crude oil for use as a feedstock. The ability to process heavy crude oil lowers our raw material costs because heavy crude oil is generally less expensive than lighter types of crude oil. Historically, heavy crude oil has accounted for 85% or more of the Cheyenne Refinery's crude oil charge. We market Cheyenne’s refined products primarily in the eastern slope of the Rocky Mountain region, which encompasses eastern Colorado (including the Denver metropolitan area), eastern Wyoming, and western Nebraska (the “Eastern Slope”). The Cheyenne Refinery's product mix includes gasoline (41%), diesel fuel (30%), and asphalt and other refined petroleum products (29%).
