About MPLX

An MPLX facility at dawn
MPLX is a diversified, large-cap master limited partnership that owns and operates midstream energy infrastructure and logistics assets and provides fuels distribution services.

Company Overview

Formed in 2012 by Marathon Petroleum Corporation (MPC), MPLX is engaged in the gathering, processing and transportation of natural gas; the transportation, fractionation, storage and marketing of natural gas liquids (NGLs); the gathering, transportation, storage and distribution of crude oil, refined products, other hydrocarbon-based products and renewables; as well as refining logistics and fuels distribution services. 

We provide these midstream services across the hydrocarbon value chain through our two business segments – Crude Oil and Products Logistics and Natural Gas and NGL Services.

MPLX's assets include:

MPLX is the primary midstream provider for MPC, which is the largest refiner in the United States in terms of refining capacity. MPC has crude oil refineries in the Gulf Coast, Mid-Continent and West Coast regions of the country. MPLX also has long-term relationships with a diverse set of producer customers in many crude oil and natural gas resource plays, including the Permian Basin, Marcellus Shale, Utica Shale, STACK Shale and Bakken Shale, among others.

MPLX continues to focus on capital discipline and free-cash-flow generation while executing on our growth capital plan. We continuously evaluate our portfolio to identify opportunities to develop, expand and participate in projects that complement our existing assets, assess strategic acquisitions and ensure all assets remain strategic to the portfolio. This includes positioning the MPLX portfolio and capabilities to be successful through an evolving energy landscape.
