Double E Pipeline, LLC owns a 135-mile interstate natural gas transmission pipeline connecting Delaware Basin gas supplies in New Mexico and West Texas with the Waha Hub. The system began operating in November 2021 and is owned 70% by Summit Midstream Corporation subsidiaries and 30% by ExxonMobil subsidiaries. Summit Midstream Permian II, LLC operates the pipeline.
On August 31, 2026, Double E approved a mainline compression expansion designed to add approximately 900 MMcf/d of transportation capacity toward Waha. The project includes a bidirectional compressor station, new plant connections and related infrastructure, with service targeted for Q4 2028, subject to regulatory approvals. Expected investment is approximately $100 million net to Summit’s 70% interest, and long-lead gas turbine compression units have already been ordered.
Air permit activity: Double E submitted an initial Permit by Rule registration on September 23, 2026, for a Mainline Compressor Station near Mentone, Loving County, Texas. The supplied TCEQ record identifies Permit 185447, Project 415278 and RN112534474. Applicable rule entries show Approve = Y, but the overall project, permit and action statuses remain PENDING, with no final completion date. Accordingly, this is a pending registration rather than a confirmed air permit approval. The station’s technical name suggests a connection to the announced expansion, although the record does not explicitly establish that relationship.
OFS sales opportunity: The expansion and station registration provide signals for construction, piping, valves, electrical systems, instrumentation, SCADA, emissions controls and maintenance services. With the main gas turbine compression units already ordered, supporting equipment and installation packages may offer more immediate opportunities.
