The heat beneath our feet flows through the earth in a complex pattern. Utah FORGE is situated in a heat reservoir that has been studied since the 1970s. In this webinar, Dr. Stuart Simmons delves into the unique geologic and geothermal resources found at Utah FORGE and the surrounding area.
What exactly are the rock types that make up the underground laboratory of Utah FORGE? In this webinar, Dr. Clay Jones describes the geology of the site and surrounding area and the findings from core and cutting analyses of deep wells!
Spanning more than 45 square miles, The Geysers in northern California is the largest geothermal power plant complex in the world. For over a century, its steam has powered innovation, clean energy, and communities across the region.
This well is the fourth and deepest of a cluster of vertical seismic monitoring wells that are located near the toe of 16A(78)-32. The well was drilled vertically to a total depth of approximately 9,000 feet about 1300 feet north of 58-32.
Well 56-32 will be fully cased (5 ½ inch) and used for deployment of seismic sensors during stimulation experiments. A Silixa DAS fiber optic cable 7500 feet long will be cemented along the outside the casing. During the drilling of 56-32, MSE (Mechanical Specific Energy) calculations and PDC bits will be used to optimize penetration rates as was successfully utilized in the drilling of 16A(78)-32. Below 7500 feet depth, mud hammer bits will be trialed and evaluated for drilling performance.

Worth noting
This well, as well as the deep, highly deviated 16A(78)-32, was drilled with specially modified polycrystalline diamond composite or PDC bits. These bits proved superior to the tricone bits used in drilling the previous wells.
According to Reed Hycalog, the bit manufacturer, drilling well 56-32 set a record for a bit run of 1208 ft in 53 hours, drilling on average 25 ft/hr in hot, crystalline granite.
Dr. Kristine Pankow of the University of Utah has been named the Geological Society of America’s 2025–2026 Distinguished Lecturer. Her lecture, “Utah FORGE: A Field-Scale Geothermal Laboratory,” will spotlight groundbreaking research at the world’s only dedicated site for advancing Enhanced Geothermal Systems.
While enjoying the first days of 2025, we’ve taken a moment to reflect on everything that Utah FORGE accomplished during the past year. There’s a lot to be proud of!
