MPLX LP operates through two primary business segments: Crude Oil and Products Logistics, and Natural Gas and NGL Services. The Crude Oil and Products Logistics segment manages a network of pipelines, marine and land terminals, and storage facilities that distribute crude oil and refined fuels. The Natural Gas and NGL Services segment focuses on gathering systems, processing plants, and fractionation facilities that separate natural gas from liquids. Headquartered in Findlay, Ohio, the partnership was established by Marathon Petroleum Corporation to serve as its primary midstream and logistics vehicle. MPLX's fee-based business model provides cash flows by charging for capacity and throughput rather than taking direct ownership of the underlying commodities.
