Refining

MPC is the second-largest crude oil refiner in the U.S. and the largest in the Midwest. We own a six-plant refinery network located in the Midwest and Gulf Coast regions of the U.S., with approximately 1,881,000 bpcd of crude oil throughput capacity. The geographic locations of our refineries provide us with strategic advantages. Our refineries are integrated with each other via pipelines, terminals and barges to maximize operating efficiency.

Our refineries have the ability to procure crude oil from a variety of supply sources, which provides us with flexibility to optimize crude supply costs. MPC processes a diverse slate of crude oil. The typical slate in 2017 consisted of about 59 percent sour crude oil and 41 percent sweet crude oil. During 2016, approximately 57 percent of this crude oil was acquired from U.S. producers, an additional 21 percent from Canada and 22 percent from other international sources.

MPC’s focus on safe, efficient and reliable operations ensures that the company’s refineries are well-positioned to address changes in the marketplace, capture commercial advantages within a strong logistics system, and seek to increase retail and brand sales volumes.
