Tejas is integral to a geothermal Project Team focused on developing, testing, and demonstrating full-scale novel geothermal products, devices, and methods of using them as a system to unlock carbon-free energy. These transformative stimulation and conformance technologies will create effective subterranean heat exchangers through long-reach, horizontal injectors and producers connected through multiple networks of induced and natural fractures. This project will significantly advance the state-of-the-art EGS well stimulation and operation technology by addressing critical technology gaps.

Colorado School of Mines (Mines) initiated the assembly of a team of experienced drilling, completions, and modeling experts from Mines and companies with extensive expertise in building and testing engineering devices, Tejas RE, KSWC Engineering and Machining, Utah Forge, and Rutgers University.

GeoThermOPTIMAL Enhanced Geothermal Systems (EGS), featuring FracOPTIMAL™ sleeves, mark a groundbreaking advancement in green energy being tested at Utah FORGE. GeoThermOPTIMAL’s novelty diverges from traditional geothermal methods by creating and managing a reservoir from hot, dry rock, allowing for efficient heat generation – even from lower-temperature sources.

The FracOPTIMAL system optimizes this process by ensuring a uniform network of fractures and precise control over water flow in the heat exchanger, which improves heat recovery and minimizes thermal decline. This advanced technology utilizes dissolvable balls to manipulate downhole sleeves, enhancing temperature control and reducing inefficiencies associated with conventional systems. GeoThermOPTIMAL offers a cost-effective, zero-carbon solution and supports energy storage, advancing the goal of a cleaner, more sustainable future.

Additionally, Rutgers University, now a team member, has developed transformative technologies that counter the adverse effects of geothermal temperatures on Portland cement.  Tejas is working with Rutgers to establish a standardized testing methodology to realize novel cement products, especially for wells subjected to geothermal temperatures of up to 1,000 degrees Fahrenheit or 540 degrees Celsius and 5,000 psi or 350 bar.

The Project Team is actively soliciting new members who have similar interests.
