The company engages in the gathering, processing and transportation of natural gas; the gathering, transportation, fractionation, storage and marketing of NGLs (natural gas liquids, such as ethane, propane, butanes, and natural gasoline); and the gathering and transportation of crude oil. The company has a presence in various natural gas resource plays, including the Marcellus Shale, Utica Shale, Huron/Berea Shale, Haynesville Shale, Woodford Shale, and Granite Wash formation where the company provides midstream services for producer customers. The company’s integrated midstream energy asset network links producers of natural gas, NGLs, and crude oil from some of the major supply basins in the United States to domestic and international markets. Its assets include approximately 5,800 million cubic feet per day of natural gas processing capacity; 379,000 Bbl/d (barrels per day) of NGL fractionation capacity; and approximately 4,000 miles of pipelines. Segments The company’s segments include Marcellus, Utica, Northeast, and Southwest. Marcellus This segment provides integrated natural gas midstream services in southwestern Pennsylvania and northern West Virginia through the company’s wholly owned subsidiary, MarkWest Liberty Midstream & Resources, L.L.C. (MarkWest Liberty Midstream). With a total processing capacity of approximately 3.2 Bcf/d, the company is the major processor of natural gas in the Marcellus Shale, and has integrated gathering, processing, fractionation, storage and marketing operations that support the improving liquids-rich natural gas production in the northeast United States. Natural Gas Gathering and Processing: The company operates five processing complexes in its Marcellus segment, including the Houston Complex located in Washington County, Pennsylvania (the ‘Houston Complex’); the Majorsville Complex located in Marshall County, West Virginia (the ‘Majorsville Complex’); the Mobley Complex located in Wetzel County, West Virginia (the ‘Mobley Complex’); the Sherwood Complex located in Doddridge County, West Virginia (the ‘Sherwood Complex’); and the Keystone Complex. In addition, the company operates two natural gas gathering systems. NGL Gathering and Fractionation Facilities: The NGLs produced at the company’s Majorsville Complex, Mobley Complex, Sherwood Complex and a third-party's Fort Beeler processing facility are gathered to the Houston Complex or to the Hopedale Complex through a system of NGL pipelines to allow for fractionation into purity NGL products. In addition, NGL's produced at a third party's processing facility in Butler County, Pennsylvania are transported through an NGL pipeline to the company’s Keystone Complex for fractionation into purity NGL products. Utica This segment includes MarkWest Utica EMG, LLC (MarkWest Utica EMG), which provides gathering, processing, fractionation and marketing services in the liquids-rich and dry-gas areas of the Utica Shale in Ohio. Natural Gas Gathering and Processing: MarkWest Utica EMG operates two processing complexes in the Utica Shale with a total capacity of approximately 925 million cubic feet of natural gas per day, such as the Cadiz Complex in Harrison County, Ohio and the Seneca Complex in Noble County, Ohio. In addition, it continues to expand its gathering system, which spans approximately 320 miles and delivers natural gas to both of the processing complexes. The company’s gathering and processing facilities are supported by long-term fee based agreements with various major producers in the Utica Shale. Fractionation Facility and Market Outlets: The Hopedale Complex is jointly owned by MarkWest Liberty Midstream and MarkWest Utica EMG, which are included in the Marcellus and Utica segments, respectively. Ethane Recovery and Associated Market Outlets: The company completed a 40,000 Bbl/d de-ethanization facility at its Cadiz Complex in 2014.
