A proven MIDSTREAM partner.


Headquartered in suburban Denver, Colorado, Stonehenge was first formed in 2007 as a partnership between Energy Spectrum Capital and 3MG Enterprises (management and certain owners of Kahuna Ventures, LLC). Our first project was the creation of Keystone Midstream Services, LLC in partnership with Rex Energy and Summit Discovery Resources II, LLC in the Appalachian Basin. MarkWest Liberty Midstream & Resources, LLC acquired the system from Stonehenge in 2012.


Today, Stonehenge operates multiple gathering and compression systems in the Appalachian Basin including Stonehenge Appalachia, Stonehenge Laurel Gathering, and Pine Run Midstream. As an established midstream operator with a proven track record of success, our goal is to support our customers through the highest standards of safety, reliability, and project execution while continuing to grow our services by leveraging our engineering expertise, operational excellence, and financial strength.
