The Permian Basin, a titan of American energy production, continues to see significant investment in its midstream infrastructure, particularly concerning the increasingly critical challenge of sour gas management. Tejon Treating and Carbon Solutions LLC has recently concluded a substantial expansion of its Mongoose amine treating plant and associated gathering network, a move poised to unlock further production potential for third-party operators in the prolific Midland Basin of West Texas. This strategic upgrade directly addresses a burgeoning need for specialized processing capabilities, signaling robust growth prospects for the region’s energy sector.
Midland Basin Sour Gas Capacity Receives Significant Boost
As of May 29, Tejon Treating officially brought online Phase 2 of its Mongoose facility, located near Westbrook, Mitchell County, Texas. This pivotal expansion dramatically elevates the plant’s sour gas treatment capacity, boosting it by an impressive 53 million cubic feet per day (MMcfd) from its initial Phase 1 capacity of 17 MMcfd. This translates to a substantial increase in throughput, enabling the processing of greater volumes of natural gas containing hydrogen sulfide (H2S), a common byproduct in many Permian wells that requires specialized handling before market delivery.
The comprehensive Phase 2 project extends beyond mere plant capacity. Tejon has also strategically enhanced its downstream delivery infrastructure, integrating new connection points that bolster market access for processed gas. A particularly noteworthy development is the tie-in to a new substation in Howard County, Texas, facilitating 100% electrification of both the Mongoose plant and its crucial compressor station. This commitment to electrification is a critical step towards reducing operational emissions, aligning with broader industry trends and investor expectations for more sustainable energy production practices.
With the completion of this expansion, Tejon now commands a formidable midstream footprint, operating over 90 miles of pipeline infrastructure dedicated to sour gas gathering. The Mongoose plant alone contributes 70 MMcfd of amine treating capacity, servicing a diverse portfolio of Midland Basin producers. These operators collectively represent an expansive 137,000 dedicated acres, underscoring the significant demand driving this infrastructure investment and the strategic importance of Tejon’s capabilities in the region.
Addressing a Critical Market Gap with Strategic Positioning
Mike Solomon, Tejon’s president, emphasized the imperative nature of this infrastructure build-out. “The strong need for reliable sour gas gathering and treating infrastructure in this specific part of the Midland Basin is undeniable,” Solomon stated. He further highlighted the company’s unique market position: “With our enhanced plant capacity, diversified takeaway options, and fully electrified operations, we are exceptionally well-placed to fill a significant market void as the exclusive sour gas treating plant in this key region.” This strategic advantage positions Tejon as a critical enabler for producers facing sour gas challenges, potentially driving further dedicated acreage and throughput volumes.
Tejon Treating and Carbon Solutions LLC itself is a relatively new entity, established in 2023 by Bayswater Management Co. LP and Bayswater Exploration & Production (E&P) LLC, both based in Denver. Initially, the Mongoose gas plant exclusively processed production from Bayswater E&P’s 35,000 dedicated acres. The current expansion to accommodate third-party volumes from 137,000 acres signifies a strategic shift towards becoming a broader, independent midstream service provider, capturing a larger share of the Midland Basin’s growing sour gas output.
Integrating Environmental Solutions: Acid Gas Injection
Beyond traditional treating, Tejon’s affiliate, Bayswater Operating Co. LLC, plays a crucial role in the sustainable management of acid gas. Bayswater operates an acid gas injection (AGI) well, AGI #1, also located in Mitchell County. This well received its initial permit from the Texas Railroad Commission (TRRC) in March 2023, allowing for the injection of up to 6.9 MMcfd of CO2 and H2S into the deep Ellenburger formation, targeting depths between 8,300 and 9,000 feet, with a maximum allowable surface pressure of 2,500 psig. This AGI well represents a critical component of the overall infrastructure, providing a safe and environmentally responsible method for disposing of the acid gas removed during the amine treating process.
In a clear indication of anticipated future growth and the need for expanded sour gas handling capabilities, Bayswater Operating is actively seeking TRRC approval. In the latter half of 2024, the company aims to increase the permitted maximum quantity of injected treated acid gas into AGI #1 by an additional 12.6 MMcfd, bringing the total permitted injection capacity to 19.5 MMcfd. This significant increase, projected for a duration of approximately 40 years, underscores the long-term vision for sustainable sour gas management in the region and the expectation of sustained, high-volume production from the Permian’s Midland Basin.
Looking Ahead: Phase 3 and Long-Term Value Creation
The strategic expansion efforts are not stopping at Phase 2. Tejon is already proactively planning for future production growth, with front-end engineering and design (FEED) studies currently underway for the addition of a third treatment train, designated Phase 3, at the Mongoose gas plant. While specific details regarding the timing and scope of Phase 3, as well as the AGI #1 expansion, are still under wraps, these preliminary studies signal a clear commitment to continuous capacity enhancement. This forward-looking approach ensures that the infrastructure remains ahead of the curve, ready to support the robust development plans of Permian producers.
For investors, Tejon’s ongoing investments in the Mongoose plant and associated infrastructure represent a compelling opportunity within the essential midstream sector. By providing critical sour gas gathering and treating services in a high-growth, infrastructure-constrained region of the Permian, Tejon is not only enabling producer activity but also mitigating environmental footprints through electrification and advanced acid gas injection. This blend of operational expansion, environmental responsibility, and strategic market positioning creates a strong value proposition, driving efficiency and sustainability across the dynamic Permian Basin energy landscape.
