MarkWest has just signed a deal with XTO Energy (XTO is a wholly-owned subsidiary of Exxon Mobil) to extend MarkWest’s natural gas liquids (NGLs) gathering pipeline in Butler County, PA to XTO’s processing plant. Previously MarkWest announced plans to extend the same pipeline from its Houston, PA complex to the Bluestone complex in Butler County. With this announcement, MarkWest will further extend the pipeline from Bluestone to XTO’s plant.
This deal will grant MarkWest the right to fractionate and market NGLs from XTO. Adding this new pipeline to other recently announced pipelines by MarkWest, when everything is built and running, MarkWest will have 3 billion cubic feet of gas processing capacity and 270,000 barrels per day of fractionation capacity throughout the Marcellus and Utica Shale.
