MarkWest Energy announces completion of Buffalo Creek plant MarkWest Energy (MWE) announced the completion of the 200M cubic feet per day Buffalo Creek cryogenic gas processing plant and associated high pressure trunk line in the Granite Wash. The Buffalo Creek facility is supported by long-term fee-based agreements with Chesapeake Energy (CHK). As part of the gas processing agreement with MarkWest, Chesapeake dedicated approximately 130K acres throughout the Anadarko Basin. The completion of the Buffalo Creek plant increases the partnership’s total processing capacity in the Anadarko Basin to 435 MMcf/d at two major complexes. The 200 MMcf/d Buffalo Creek facility and the 235 MMcf/d Arapahoe processing complex in Western Oklahoma are connected through the Partnership’s rich-gas gathering system, which provides 575 MMcf/d of gathering throughput capacity and flexibility and reliability. MarkWest’s infrastructure also provides producers with multiple residue gas outlets and access to natural gas liquids takeaway pipelines to Mt. Belvieu and Conway. MarkWest anticipates volumes at the new plant to ramp quickly as Chesapeake has approximately 100 MMcf/d of existing production that the Partnership has begun to process.
