MarkWest Liberty Midstream & Resources said that it will construct a midstream 120 million cubic feet per day (mmcf/d) cryogenic gas processing facility and associated natural gas liquids (NGL) pipeline by mid 2012 in Logansport, West Virginia.

The facility will be used to process liquids-rich gas transported in EQT Corporation’s Equitrans gas pipeline, which recently announced a significant expansion to increase transmission capacity.

EQT has substantial rich-gas Marcellus acreage in northern West Virginia and has contracted with MarkWest Liberty for the majority of the Logansport plant capacity.

The NGLs recovered at Logansport will be transported through pipeline to MarkWest Liberty’s fractionation, storage, and marketing complex in Houston, Pennsylvania.

The new processing facility and associated NGL pipeline significantly expands the integrated processing, fractionation, and NGL marketing services that MarkWest provides to producers in the Appalachian region.
