Marathon Petroleum Corporation (MPC) is one of the largest integrated downstream energy companies in the United States, with more than 135 years of experience in the energy sector. Its operations are focused primarily on refining and marketing, where it boasts a refining capacity of approximately 3.0 million barrels per day across its refineries located in key regions including the Gulf Coast, Mid-Continent, and West Coast. MPC also has a significant footprint in the midstream market through its subsidiary MPLX, managing a network that connects natural gas and natural gas liquids producers to domestic and international markets. This integrated approach allows MPC to optimize logistics and enhance operational efficiency in its refining processes.
Separating its business into two segments—Refining & Marketing and Midstream—MPC not only refines crude oil and renewable feedstocks but also sells a wide array of refined products such as gasoline, diesel, propane, and asphalt both domestically and internationally. The company leverages its extensive distribution network, including terminals and a sizable fleet of barges, to maximize market reach. Recent expansions, such as the acquisition of Andeavor, have strengthened its competitive positioning, allowing it to optimize operations and expand its geographic footprint significantly.
