Key Terms

produced-water, joint industry project (jip), desalination, flow-assurance

4 terms

produced-water technical

"transform a produced-water stream from a disposal challenge into a valuable resource"

Produced water is the salty, often chemically altered water that comes up from underground along with oil and gas during production. Like wastewater from a factory, it can carry hydrocarbons, salts and chemicals and therefore creates costs and environmental risks for operators; managing, treating or disposing of it affects operating expenses, regulatory compliance and potential liabilities, so investors watch it as a driver of cash flow and risk exposure.

joint industry project (jip) technical

"The produced-water treatment pilot facility is a Joint Industry Project (JIP)"

A joint industry project (JIP) is a collaborative research or development effort where multiple companies share funding, resources and data to tackle a common technical or regulatory challenge. For investors, JIPs matter because they spread cost and risk across participants, can speed innovation or compliance by pooling expertise, and may affect future revenue or competitive position depending on how results and intellectual property are shared—think of it like neighbors pooling money to build a shared tool everyone can use.

desalination technical

"guide the next phase of commercial-scale desalination facilities"

Desalination is the process of removing salt and other minerals from seawater or brackish water to produce fresh water people and businesses can use, similar to running salty water through a large, industrial filter or distillation system. It matters to investors because desalination plants are capital-intensive, often produce steady long-term revenue from water sales or contracts, and are sensitive to energy costs, regulation and environmental concerns—factors that affect profitability and risk.

flow-assurance technical

"using all of today's oil and gas flow-assurance solutions: water sourcing, recycling"

Flow-assurance is the set of practices and technologies used to keep oil, gas or other fluids moving smoothly through wells and pipelines, preventing blockages, corrosion or pressure problems—think of it as winterizing a long, industrial plumbing system to stop freezes and clogs. For investors, strong flow-assurance means steadier production, lower maintenance and safety risks, and more predictable revenue from an energy asset; failures can lead to costly shutdowns and lost output.

• The produced-water treatment pilot facility is a Joint Industry Project (JIP) between Western Midstream, Chevron, ConocoPhillips, Devon, and ExxonMobil.
• The facility is designed to produce approximately 1,000 barrels per day of reclaimed freshwater – ten times the amount of JIP 1.
• The facility's water output is expected to contribute to long-term water security in West Texas.

HOUSTON, June 17, 2026 /PRNewswire/ -- Today, Western Midstream Partners, LP (NYSE: WES) ("WES" or the "Partnership"), alongside its Joint Industry Project (JIP) collaborators Chevron U.S.A. Inc. ("Chevron"), ConocoPhillips Company ("ConocoPhillips"), Devon Energy Corporation ("Devon"), and Exxon Mobil Corporation ("ExxonMobil"), announced the start-up of its second produced-water treatment pilot facility ("JIP 2") near Red Bluff Reservoir in Reeves County, Texas. The facility is designed to receive 2,000 barrels per day of produced water and produce approximately 1,000 barrels per day of reclaimed freshwater, or approximately ten times the amount produced by JIP 1. This new facility builds upon the success of JIP 1 (described below) which evaluated and field-tested multiple produced-water treatment technologies to select preferred, high-performing solutions for ongoing operations.

In 2023, WES and its collaborators created JIP 1, a small-scale pilot site in West Texas, to evaluate and measure technologies needed to commercialize beneficial use of produced water in the Permian Basin. During the 24-month project, technical experts at WES and its collaborators collected over 50,000 water quality data points to demonstrate a treatment process that can consistently produce water quality suitable for end-use applications that include industrial cooling, irrigation, and surface discharge.

The JIP 2 facility will also serve as a demonstration site, enabling continued optimization of operations while validating consistent reclaimed freshwater production for a range of end-use applications. Insights and data collected from JIP 2 will guide the next phase of commercial-scale desalination facilities. WES and its JIP collaborators will continue to work closely with regulators, local communities, and independent experts to further validate the treatment process and confirm water quality outcomes. These investments are aimed at reducing industry disposal volumes while developing a potential alternative water source benefiting industry and surrounding communities.

"The start-up of JIP 2 marks a pivotal milestone in our journey to transform a produced-water stream from a disposal challenge into a valuable resource for the Permian Basin and beyond," said Oscar K. Brown, President and Chief Executive Officer of WES. "Through our multi-barrier treatment approach, we are transforming that stream into highly treated reclaimed freshwater suitable for industrial cooling and irrigation applications, while helping reduce pressure on Texas' limited water resources. WES already handles approximately 3.0 million barrels per day of produced water using all of today's oil and gas flow-assurance solutions: water sourcing, recycling, gathering, long-haul transportation, and disposal, and we believe beneficial reuse will be the next major solution to the Permian Basin's water challenges. We are very proud of the progress our team and our JIP members have made together over the past two years, and we believe JIP 2 brings us meaningfully closer to WES's first commercial-scale facility."
