Yellow slickers at Billings Refinery

About us

The Billings Refinery started operations in 1949, processing an average of 20,000 barrels per day of crude oil.

In 1954, the installation of the first fluid coker in the world enabled the refinery to take advantage of heavy crude. Since that time, the refinery has grown to include 18 major processing units, increasing capacity to roughly 60,000 barrels of crude oil per day and producing about 600 million gallons of gasoline and diesel fuel annually.

Located on the bank of the Yellowstone River near Lockwood, Montana, the refinery covers 720 acres, which includes about 370 acres of undeveloped land and urban wildlife habitat area. The refinery employs more than 270 people and about 100 of contractors on a daily basis.

Crude oil is supplied by producers in Wyoming and Alberta, Canada. Employing industry-leading technologies our products include all grades of gasoline, conventional gasoline blendstocks for blending with ethanol, ultra low sulfur diesel fuels, asphalt, butane and propane. The distribution market includes Montana, Wyoming, Utah, Colorado, South Dakota, Washington, Idaho and parts of Nevada.
