Crestwood Equity Partners LP (NYSE: CEQP) (“Crestwood Equity” or “Crestwood”) today announced it has entered into new, long-term commercial agreements with BlueStone Natural Resources II, LLC (“BlueStone”) to gather and process natural gas across its Alliance, Lake Arlington and Cowtown systems in the Barnett Shale. Under the terms of the agreement, Crestwood will provide services to BlueStone for a period of 10 years under a fixed-fee and percent of proceeds fee structure. As part of the agreement, BlueStone has provided production assurance to Crestwood whereby across all systems BlueStone will return currently shut-in wells to production by July 1, 2016 and will not shut-in or choke back production for economic purposes through the end of 2018.

On April 6, 2016, BlueStone closed the acquisition of Quicksilver Resources Inc. (“Quicksilver”) Barnett Shale assets. In connection with the closing, Quicksilver withdrew its motion to reject Crestwood’s legacy gathering agreements relating to its Barnett Shale assets.

“I am pleased to announce our new long-term relationship with BlueStone, which will bring an experienced and financially sound oil and gas operator to our Barnett Shale systems and final resolution to Crestwood’s participation in the Quicksilver bankruptcy process,” stated Robert G. Phillips, Chairman, President and Chief Executive Officer of Crestwood’s general partner. “BlueStone has significant experience in the Barnett Shale with specific expertise in low cost operations and growing production through optimizing existing producing wells as well as developing new drilling locations. The new agreements provide for comparable gathering, processing, compression and treating services to BlueStone, are in-line with our previously announced 2016 guidance, are designed to maximize production in the current low commodity price environment and provide significant upside to both Crestwood and BlueStone as commodity prices recover. The partnership with BlueStone provides visibility to regaining volume growth on the system and Crestwood looks forward to providing strong customer service as both parties work to revitalize this premier, low cost natural gas resource.”

BlueStone, formed in 2012, specializes in the development of oil and gas properties in the South Texas and Barnett Shale plays and is sponsored by Natural Gas Partners. BlueStone is headquartered in Tulsa, Oklahoma.
