Summit Advances Double E Expansion with New Permian Contracts

Summit Midstream is advancing expansion of the Double E pipeline in the Permian, backed by new long-term gas transportation agreements and a capacity increase of up to 50%.

(P&GJ) — Summit Midstream is advancing expansion of its Double E natural gas pipeline in the Permian Basin, supported by new long-term transportation agreements and a planned capacity increase of up to 50%, according to its latest earnings release.

The company has launched a binding open season to support a mainline compression project that would increase Double E capacity from approximately 1.6 billion cubic feet per day to about 2.4 billion cubic feet per day by the end of 2028.

The expansion effort follows multiple new long-term, take-or-pay agreements with shippers that are expected to significantly increase throughput on the system over the next several years. Summit said the additional contracts could drive Permian segment Adjusted EBITDA from $34 million in 2025 to approximately $60 million by 2029.

Recent agreements include an 11-year transportation deal for 210 million cubic feet per day, with volumes beginning in late 2026 and ramping up through 2028, as well as another 11+ year agreement for 230 million cubic feet per day tied to future processing plant expansion.

The Double E system continues to expand its downstream connectivity, adding delivery points into the Transwestern Central Pool, the Hugh Brinson Pipeline and a planned connection to the Desert Southwest Pipeline, improving access to Gulf Coast markets.

Summit also recently refinanced the Double E capital structure with a $440 million term loan, which will fund ongoing expansion projects, including the compression upgrade.

Outside the Permian, the company is growing its crude oil footprint in the Williston Basin, where it signed a new 10-year gathering agreement covering more than 200,000 acres in North Dakota. The deal is expected to support additional drilling and system expansion across the region.

Summit said producer activity remains steady across its systems, with seven rigs currently running and up to 126 wells expected to come online in 2026, supporting continued throughput growth.

Heath Deneke, President, Chief Executive Officer and Chairman, commented, "We are pleased with the commercial and financial progress achieved over the past two quarters, which underscore the strategic value of our infrastructure, embedded growth opportunities, and our continued focus on execution with financial discipline. With the signing of major long-term agreements on the Double E Pipeline and in the Williston Basin, we are building on strong commercial momentum in our Permian and Rockies segments, while maintaining steady operational performance, strengthening our balance sheet and allocating capital prudently."
