MPLX LP

MPLX is a diversified, growth-oriented master limited partnership formed in 2012 by MPC to own, operate, develop and acquire midstream energy infrastructure assets. We are engaged in the gathering, processing and transportation of natural gas; the gathering, transportation, fractionation, storage and marketing of NGLs; the gathering, transportation and storage of crude oil and refined petroleum products; and fuels distribution services. MPLX provides services in the midstream sector across the hydrocarbon value chain through our Logistics and Storage and Gathering and Processing segments.

Logistics and Storage

MPLX transports and stores crude oil, refined products and other hydrocarbon-based products, primarily in the Midwest and Gulf Coast regions of the U.S. Assets consist of a network of wholly- and jointly-owned common carrier crude oil and refined product pipeline systems and associated storage assets, refined product terminals, storage caverns and an inland marine business. 

We own, lease, operate or have interest in approximately 10,000 miles of crude and refined product pipelines. We also own, lease or have interest in 62 light product terminals in the Midwest, Gulf Coast and Southeast regions of the United States. Our terminal facilities are used for the receipt, storage, blending, additization, handling and delivery of refined petroleum products. We have butane and propane storage caverns in Illinois, Michigan and West Virginia.

In addition, MPLX provides fuels distribution services to MPC and owns refining logistic assets consisting of tanks with approximately 56 million barrels as well as refinery docks, loading racks and associated piping.

MPLX’s marine operations include 20 owned towboats as and more than 240 owned and leased barges that transport refined products and crude oil on the Ohio, Mississippi and Illinois rivers and their tributaries and inter-coastal waterways. Our marine repair facility is a full-service marine shipyard located on the Ohio River adjacent to MPC’s Catlettsburg refinery.

We also have interest in various joint-interests, including LOOP LLC, the only U.S. deep water oil port located offshore in Louisiana, which offloads crude oil from marine vessels destined for onshore storage and pipeline transport.

Gathering and Processing

MPLX operates several natural gas gathering systems, which have a combined throughput capacity of 5.9 bcf/d. The scope of gathering services we provide depends on the composition of the raw or untreated gas at producer customers’ wellheads. For dry gas, we gather, and if necessary, treat the gas and deliver it to downstream transmission systems. For wet gas that contains heavier and more valuable hydrocarbons, we gather the gas for processing at a processing complex.

MPLX’s natural gas processing complexes remove the heavier and more valuable hydrocarbon components from natural gas. We operate natural gas processing complexes in the Marcellus shale, Utica shale, Appalachia region, and Southwest region with approximately 8.7 bcf/d of natural gas processing capacity.

Once natural gas has been processed at a natural gas processing complex, the heavier and more valuable hydrocarbon components, which have been extracted as a mixed NGL stream, can be further separated into their component parts through the process of fractionation. Our NGL fractionation facilities have a capacity of approximately 610,000 bpcd and separate the mixture of extracted NGLs into individual purity product components for end-use sale. We sell basic NGL products, including ethane, propane, normal butane, isobutene, natural gasoline and other primary products such as ethylene and propylene.
