MarkWest to expand Marcellus processing capacity

Denver-based MarkWest Energy Partners plans to expand its rich-gas processing facilities in West Virginia to handle growing production from the Marcellus Shale.

The midstream company is adding two cryogenic processing plants at its Sherwood complex in Doddridge County, West Virginia, and its Mobley Complex in Wetzel County, West Virginia.

At the Sherwood complex, MarkWest will build a processing plant that can handle 200 million cubic feet per day (MMcf/d) at the request of Denver driller Antero Resources. The new plant will be anchored by a long-term, fee-based contract and will expand total capacity at Sherwood to 1.2 billion cubic feet (Bcf/d) by the second quarter of 2015.

At the Mobley complex, MarkWest will increase total processing capacity to 920 MMcf/d with the construction of an additional 200 million cubic feet per day processing plant at the request of Pittsburgh driller EQT Corp. The new plant is anchored by a long-term, fee-based contract and also is expected to be in service by the second quarter of 2015.

Currently, the Mobley complex consists of three plants with 520 MMcf/d of total processing capacity.

During the fourth quarter of 2014, MarkWest will begin operations of a fourth plant at Mobley, increasing capacity to 720 MMcf/d. The complex supports growing Marcellus rich-gas production from EQT, Magnum Hunter Resources, Stone Energy, Consol Energy and Noble Energy.

MarkWest has 17 major processing and fractionation projects under development in the Marcellus and Utica shale regions. In 2014, MarkWest expects to complete 11 of these projects, bringing total Northeast processing and fractionation capacity to 4 Bcf/d and 250,000 barrels per day, respectively.
