A May, 2009 report stated that Mark West Energy and NGP Midstream & Resources LP (M&R) closed a joint venture known as MarkWest Liberty Midstream & Resources. It is to focus on construction and operation of midstream services in support of Marcellus shale gas production for its customers. It is 40 percent owned by M&R and 60 percent by MarkWest and operated by the latter. MarkWest contribued roughly $100 million of its existing Marcellus assets. M&R will contribute $200 million which is roughly the amount needed to fund the project during 2009. MarkWest will invest yet another $200 million by the end of 2011.

Also in May, MarkWest announced several new developments for its Liberty joint venture-

* a new cryogenic plant with throughput of 30 Mmcf/d in southwestern 
 Pennsylvania. (Update: August, 2009 - start-up announced)
* a new 80 to 100 Mmcf/d refrigeration plant by year-end-2009. 
* a 120 Mmcf/d cryogenic processing plant in early 2010 in Houston, PA.
* a second 120 Mmcf/d cryogenic plant roughly 30 miles SW of Houston. 
Also, it already operates:
* (Update: August, 2009) a mechanical refrigeration processing plant with 
  capacity of 40 Mmcf/d. 
* six compressor stations. 
* three more compressor stations to be added by year-end-2009.
MarkWest planed to build natural gas liquids (NGL) infrastructure:
* pipeline capacity
* storage
* rail car and truck loading facility

September, 2009 found MarkWest Liberty forming a strategic alliance with Chesapeake Energy and Statoil-Hydro to process gas gathered and collected from the latter two company's Marcellus shale wells in Marshall and Wetzel counties in northern West Virginia. The gas is to be processed at a new plant MarkWest Liberty had been building adjacent to an existing compression facility operated by Columbia Natural Gas. The new plant was to be located on the West Virginia - Pennsylvania border in Majorsville about a dozen miles southeast of Wheeling, WV.

MarkWest Liberty had also been planning a 37,000 bbl/d fractionation plant at their existing Houston, PA complex. The Majorsville plant was to have a connecting pipeline to the Houston one from where the gas is to be marketed as hydrocarbon liquids to eastern U.S. metropolitan areas.
