MPLX LP (MPLX) is a diversified, growth-oriented master limited partnership formed in 2012 by Marathon Petroleum Corporation to own, operate, develop and acquire midstream energy infrastructure assets. MPLX provides services in the midstream sector across the hydrocarbon value chain through the 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 crude oil and refined product pipeline systems, associated storage assets and an inland marine business.
MPLX owns, leases, operates or has interest in 3,500 miles of crude oil pipelines and 2,400 miles of light product pipelines. MPLX also has 59 owned and operated, one leased and two partially owned light product terminals, butane and NGL storage caverns, an inland marine business, crude oil and product storage facilities (tank farms) and a barge dock facility.
MPLX’s marine transportation operations include 18 owned towboats as well as more than 200 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.
GATHERING AND PROCESSING
MPLX operates several natural gas gathering systems in six states. The scope of gathering services provided depends on the composition of the raw or untreated gas at producer customers’ wellheads. MPLX’s natural gas processing complexes remove the heavier and more valuable hydrocarbon components from natural gas. MPLX currently operates natural gas processing complexes in the Marcellus shale, Utica shale, Appalachia region, and Southwest region.
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 natural gas liquid (NGL) stream, can be further separated into their component parts through the process of fractionation. Our NGL fractionation facilities separate the mixture of extracted NGLs into individual purity product components for end-use sale.
Assets include approximately 5.6 billion cubic feet per day of gathering capacity, 7.8 billion cubic feet per day of natural gas processing capacity and 570,000 barrels per day of fractionation capacity.
