MarkWest Utica EMG Expands Utica Shale Midstream Infrastructure

July 2013, Vol. 240 No. 7

MarkWest Utica EMG LLC, a joint venture between MarkWest Energy Partners LP and The Energy and Minerals Group, plans another expansion of its large-scale midstream system to support the drilling programs of Antero Resources, Gulfport Energy Corp. and other producers in the southern core of the Utica Shale. MarkWest Utica EMG will add a third 200 MMcf/d cryogenic gas processing plant at its Seneca processing complex in Noble County, OH.

The Seneca complex continues to expand and will include three processing plants totaling 600 MMcf/d. The first two plants will begin operations later this year and will support rich-gas production from a number of key producers. In addition to the Seneca I facility, Antero’s rich-gas production will anchor the Seneca III facility, and MarkWest Utica EMG expects the plant to be operational early next year.

In just over a year, MarkWest Utica EMG has made agreements with seven producers in the southern core of the Utica Shale. By mid-2014, MarkWest Utica EMG’s fully integrated midstream system will consist of more than 300 miles of gathering pipeline, five processing facilities totaling almost 1 Bcf/d and 100,000 bpd of C2+ fractionation capacity.
