Summit Investments Announces Expansion Of Its Crude Oil And Water Gathering System In Bakken Shale Play

Dallas, TX /PRNewswire/ - Summit Midstream Partners, LLC ("Summit Investments"), the privately held company that owns and controls the general partner of Summit Midstream Partners, LP (NYSE: SMLP) and also owns a 71.6% limited partner interest in SMLP, announced today a significant expansion of its Divide crude oil and water gathering system currently under construction in Williams and Divide counties in North Dakota. In addition to the approximately 90 miles of crude gathering pipeline being constructed as part of the Divide system, Summit Investments will construct approximately 145 miles of new gathering pipeline capable of handling up to 45,000 barrels of crude oil and 45,000 barrels of water per day. The expansion is supported by the recent execution of a new, ten year, fee-based crude oil and water gathering agreement covering 250,000 dedicated acres with a leading independent producer in the Bakken Shale Play. The total capital expenditures for the expansion are approximately $60 million and will add to the approximately $200 million of expansion capital being spent by Summit Investments in 2013. The expansion is expected to be put in service in phases between the fourth quarter of 2013 and the first quarter of 2014.

Steve Newby, President and CEO of Summit Investments commented, "The execution of this new commercial agreement reflects the next step in our growth strategy to expand our presence in the Bakken Shale Play through organic development projects. We are excited to expand our existing crude oil and water gathering service offerings to new customers that are actively drilling around our Divide system, and we expect to continue to expand our gathering system with other producers that are active in the area. This development will add additional scale to our already large inventory of future drop down opportunities for SMLP."
