Catlettsburg Refinery

Our Catlettsburg refinery is in northeastern Kentucky on the western bank of the Big Sandy River, near the confluence with the Ohio River and has a total crude oil refining capacity of 300,000 barrels per calendar day (bpcd).

The Catlettsburg refinery processes sweet and sour crude oils into gasoline, distillates, asphalt, natural gas liquids and petrochemicals, propane and heavy fuel oil. MPC completed construction of a condensate splitter in 2015, increasing the refinery’s capacity to process condensate from the Utica shale region. Pipelines, barges, transport trucks and rail are used to distribute products.
