We are an independent energy company, organized in the State of Wyoming in 1977, engaged in crude oil refining and the wholesale marketing of refined petroleum products. We operate refineries in Cheyenne, Wyoming and El Dorado, Kansas with a total annual average crude oil capacity of approximately 187,000 barrels per day. Both of our refineries are complex refineries, which means that they can process heavier, less expensive types of crude oil and still produce a high percentage of gasoline, diesel fuel, and other high value refined products. We focus our marketing efforts in the Rocky Mountain region and the Plains States, which we believe are among the most attractive refined products markets in the United States. Long after the Spanish gave up looking for El Dorado and its reputed gold on the high plains of the New World, Frontier El Dorado Refining is processing black gold in El Dorado, Kansas. A subsidiary of Frontier Oil, the company operates the El Dorado 130,000 barrels-per-day refinery, the largest refinery and the only petrochemical plant in Kansas. The El Dorado Refinery's product mix includes gasoline (55%), diesel and jet fuel (34%) and asphalt, chemicals and other refined petroleum products (11%). Frontier El Dorado ships its products to markets in the Plains and Rocky Mountain states.
