|The Casper Refinery is a medium conversion refinery based in Casper, Wyoming. Starting operations as White Eagle Refinery in 1923, it remains one of the oldest refineries still operating in the Rocky Mountains today. It was acquired from Mobil Oil in 1968 and named the Little America Refining Company. Casper is a central hub for crude oil supplies and the refinery is capable of running a large array of crude oils, including domestic and Canadian synthetic crudes.
The refinery produces more than 1,000,000 gallons of product per day. The Casper Refinery has been updated to produce ultra-low sulfur diesel and recently installed projects to lower gasoline sulfur levels and increase gasoline production and octane levels. The refinery is an economic cornerstone for central Wyoming and many of its products are used by heavy equipment users and commercial companies throughout Wyoming.
In 2009, the refinery received the Gold Award for Achievement in Safety from the National Petrochemical and Refiners Association.
