Located in Billings, Montana, our Billings Refinery processes a mixture of Canadian heavy, high-sulfur crude oil plus domestic high-sulfur and low-sulfur crude oils, all delivered by pipeline and truck.

The facilities have fluid catalytic cracking, naphtha reforming and hydrodesulfurization units. A delayed coker converts heavy, high-sulfur residue into higher-value light oils. The refinery produces a high percentage of gasoline, diesel and aviation fuels as well as fuel-grade petroleum coke. Finished petroleum products from the refinery are delivered by pipeline, railcar and truck. Pipelines transport most of the refined products to markets in Montana, Wyoming, Idaho, Utah, Colorado and Washington.

The Billings Refinery was awarded the 2016 ENERGY STAR certification in recognition of its efforts to reduce greenhouse gas emissions through energy efficiency.
