Mark West Energy Partners Add Processing Infrastructure In West Virginia

December 2012, Vol. 239 No. 12

MarkWest Energy Partners is developing additional processing infrastructure at its Mobley complex in Wetzel County, WV. MarkWest will construct Mobley III, a 200 MMcf/d gas processing facility, to support development of rich-gas acreage in the Marcellus Shale by EQT Corp. and other producers. The additional Mobley plant is supported by long-term, fee-based contracts.

MarkWest expected to complete construction of its first 200 MMcf/d Mobley facility shortly. The second facility, a 120 MMcf/d plant, will be operational by early 2013 and is primarily supported by growing rich-gas development of Magnum Hunter Resources and third parties. MarkWest’s planned construction of Mobley III is expected to be complete by late 2013. Once the projects are operational, the Mobley complex will have 520 MMcf/d of processing capacity.

By mid-2013, MarkWest will have the ability to extract ethane with the completion of 78,000 bpd of combined de-ethanization facilities at its Majorsville and Houston complexes. Ethane recovered by MarkWest will have access to all of the planned ethane pipeline projects that will originate from its Houston complex.
