- MPLX LP is a diversified master limited partnership primarily engaged in the ownership, operation, and development of midstream energy infrastructure and logistics assets in the United States. The company’s core products and services include the gathering, processing, and transportation of natural gas; gathering, transportation, fractionation, storage, and marketing of natural gas liquids (NGLs); and the gathering, storage, transportation, and distribution of crude oil and refined petroleum products. Additionally, MPLX operates an extensive network of crude oil and refined product pipelines; an inland marine business that transports light products, heavy oils, crude oil, renewable fuels, chemicals, and feedstocks via a fleet of boats and barges; and terminal facilities for receipt, storage, blending, additization, handling, and redelivery of refined petroleum products via pipeline, rail, marine, and truck transportation. It also manages refinery logistics, terminals, rail facilities, storage caverns, and crude and light-product marine terminals.
MPLX LP is organized into two main operating segments: Logistics and Storage (L&S), which includes crude oil and refined product transportation, storage, and distribution infrastructure largely supporting Marathon Petroleum Corporation’s refining system; and Gathering and Processing (G&P), which focuses on natural gas gathering, processing, and NGL fractionation primarily in the Marcellus, Utica, and Permian basins. The company’s operations are concentrated in key U.S. energy-producing regions, including the Midwest, Gulf Coast, and West Texas. MPLX is a subsidiary of Marathon Petroleum Corporation and was founded in 2012, with its headquarters located in Findlay, Ohio.
Recent major developments include a strategic collaboration announced in November 2025 with MARA Holdings, Inc. to supply natural gas from MPLX’s Delaware Basin processing plants to integrated power generation facilities and data center campuses in West Texas. This partnership aims to enhance natural gas demand within the basin, improve power reliability for MPLX’s operations and its producer-customers, and support MARA’s data center energy needs. Additionally, MPLX continues to focus on expanding its integrated NGL value chain, particularly in the Permian Basin, following recent inorganic growth investments and acquisitions such as the Northwind acquisition, which added sour gas treating capabilities in the Delaware Basin. MPLX also consistently invests in operational efficiency and asset integrity to support stable, fee-based cash flows under long-term contracts. In October 2025, MPLX increased its quarterly distribution by 12.5%, reflecting confidence in its cash flow stability and growth prospects.
Overall, MPLX LP operates as a key midstream energy infrastructure player with a comprehensive suite of services addressing the transportation, storage, processing, and logistics needs of crude oil, refined products, natural gas, and NGLs across multiple U.S. regions, supported by strategic partnerships and continuous asset base enhancements.
