Pipeline giant MarkWest has just gobbled up another, albeit much smaller, competitor. MarkWest announced yesterday it is purchasing Keystone Midstream for $512 million. Keystone is owned by Stonehenge Energy Resources and Rex Energy with operations primarily in Butler County, PA.
As part of the deal, MarkWest will gain contracts and a partnership with Rex Energy and Sumitomo Corporation to transport and process their rapidly expanding production in the liquids-rich portion of the Marcellus Shale in Butler and Beaver counties in Pennsylvania. MarkWest and Rex are also exploring a deal for Utica Shale production in eastern Ohio.
