MarkWest Energy Partners LP plans to add midstream infrastructure at its Keystone complex in Butler County, Pa., to support growing rich gas production from the Marcellus Shale and Upper Devonian formations.
According to a press release, MarkWest will build two 200-million-cubic-feet-per-day processing plants called Bluestone III and IV. The company expects the plants to be operational during the fourth quarter of 2015 and the second quarter of 2016, respectively.
The company also plans to construct 40,000 barrels per day of additional de-ethanization capacity and more than 20,000 barrels per day of additional propane and heavier NGL fractionation capacity.
