Antero Midstream, a company owning, operating, and developing midstream energy assets, completed the acquisition of gas gathering and compression assets in the Marcellus Shale from Summit Midstream Partners, a limited partnership focused on midstream energy infrastructure development, for $70m. "This transaction marks our third highly strategic bolt-on acquisition in Appalachia in the last two years. The compression and high pressure gathering assets are already interconnected with Antero Midstream's low pressure gathering system. As a result of this transaction, Antero Midstream now gathers and compresses substantially all of Antero Resources' production," Paul Rady, Antero Midstream Chairman and CEO.
