The Department of Energy Advanced Research Projects Agency awarded a Cooperative Agreement totaling $5.205 million to the University of Texas at Austin on November 4, 2025, under the Advanced Research Projects Agency - Energy program (CFDA 81.135).

The award funds development of a high-temperature sliding sleeve that operates at temperatures up to 225°C to improve energy recovery rates in enhanced geothermal systems. The sleeve incorporates zonal isolation to create individual fractures with defined geometries, employs an alternate-stage sequencing method to ensure fractures are orthogonal to the wellbore, and controls flow distribution by adjusting slot opening in each sleeve. These innovations address challenges in geothermal energy extraction.

Performance occurs in Austin, Texas, with a period of performance extending from November 4, 2025, through November 3, 2028. The University of Texas System is the parent entity.

Two sub-recipients pass through funding to deliver components of the project. Neubrex Energy Services (US), LLC received a sub-award effective March 10, 2026. NCS Multistage, LLC received a sub-award effective February 17, 2026. Both sub-recipients contribute to the improved energy recovery rate work under the same project title.
