Refining Operations

Our refining operations are located in Cheyenne, Wyoming; El Dorado, Kansas; Artesia, New Mexico; Tulsa, Oklahoma and Woods Cross, Utah.  Each of the refineries has the complexity to convert discounted, heavy and sour crude oils into a high percentage of gasoline, diesel and other high value refined products.  The Company markets products primarily throughout the Rocky Mountains, Plains states and Southwestern regions, which are among the most attractive refined product markets in the United States.

Cheyenne Refinery
The Cheyenne Refinery is located in Cheyenne, Wyoming and has a crude oil capacity of 52,000 barrels per day with the complexity to convert a wide variety of crude oils into a high percentage of light products. Crude oil is purchased from local producers, including the nearby Niobrara and Bakkenformations and is also imported via the Express Pipeline from Canada.  Cheyenne refined products are primarily marketed in the eastern slope of the Rocky Mountain region, which encompasses eastern Colorado (including the Denver metropolitan area), eastern Wyoming, and western Nebraska.

El Dorado Refinery
The El Dorado Refinery is located in El Dorado, Kansas and is one of the largest refineries in the Plains States and 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 due to its direct pipeline access to the Cushing, Oklahoma hub, which is connected by pipelines to the Gulf Coast, Canada and a majority of U.S. crude production. This crude oil access, combined with the refinery's complexity, gives it the flexibility to refine a wide variety of crude oils.  El Dorado refined products are marketed primarily throughout the Plains States and eastern slope of the Rocky Mountain region, which encompasses eastern Colorado (including the Denver metropolitan area) and eastern Wyoming.

Navajo Refinery
The Navajo Refinery is located in Artesia, New Mexico and has a crude oil capacity of 100,000 barrels per day with the flexibility and complexity to process heavy crude oil, sour crude oil and light sweet crude oil. The refinery is in close proximity to West Texas crude supply and also has direct pipeline access to the wide variety of crude oils in Cushing, Oklahoma, including Canadian crudes.  Navajo refined products are marketed primarily in the southwestern United States and northern Mexico.

Tulsa Refinery
The Tulsa Refinery is located in Tulsa, Oklahoma and has a crude oil capacity of 125,000 barrels per day.   The Tulsa Refinery primarily processes sweet crude oils, but can also process sour crude oils and sits adjacent to Cushing, Oklahoma, the largest crude oil trading hub in the U.S.  Tulsa refined products are marketed primarily throughout the midcontinent region of the United States. The Tulsa Refinery also manufactures lubricants and specialty waxes, including lubricating oils (base, blended and process oils), waxes, horticultural oils and asphalt modifiers, which are marketed by Holly Lubricants. 

Woods Cross Refinery

The Woods Cross Refinery is located just north of Salt Lake City, Utah and has a crude oil capacity of 31,000 barrels per day.  The Woods Cross Refinery is a high conversion refinery that has advantaged access to regional sweet and black wax crudes as well as pipeline access to Canadian crude oils.  Woods Cross refined products are marketed primarily in Utah, Idaho, Nevada, Wyoming and eastern Washington.

Holly Energy Partners

HollyFrontier owns a 34% interest, including the 2% general partnership interest, in Holly Energy Partners, L.P. (NYSE: HEP), a master limited partnership that owns and operates petroleum logistics assets including pipelines, terminals and tankage throughout the midcontinent.  Through subsidiaries, HEP owns or leases approximately 2,500 miles of petroleum product and crude oil gathering pipelines in Texas, New Mexico, Oklahoma and Utah.  HEP also owns tankage and refined product terminals in several Southwest and Rocky Mountain states.

UNEV Pipeline

The UNEV pipeline is a joint venture with Sinclair Corporation to build and operate a refined products pipeline from Salt Lake City, Utah to Las Vegas, Nevada along with associated terminal facilities in Cedar City, Utah and North Las Vegas, Nevada. HollyFrontier owns a 75% interest in the joint venture, and Sinclair owns the remaining 25% interest. The initial capacity of the pipeline will be 62,000 barrels per day (“bpd”), with the capacity for further expansion to 120,000 bpd. The current total cost of the pipeline and terminal project is expected to be approximately $340 million, with the HollyFrontier share of the cost totaling $255 million. This project includes the construction of ethanol blending and storage facilities at the Cedar City terminal. The pipeline is in the final construction phase and is expected to be mechanically complete late summer 2011.
