BTU Graph brief

Marathon Petroleum spans conversion and logistics: refinery economics interact with crude supply, terminal and pipeline access, product distribution, retail demand, and renewable feedstocks.

What Marathon Petroleum does

Marathon Petroleum operates petroleum refineries, product marketing and branded fuel distribution, renewable-fuel facilities, and marine, pipeline, and terminal logistics in the United States.

Its relationship with MPLX adds gathering, processing, and transportation exposure to the downstream system. Researchers should separate the refining and marketing company from the midstream partnership while mapping their integration.
