Overview
- An appraisal well reached about 11,200 feet and was drilled in under 11 days, with temperature logs placing the site above the 95th percentile for deep geothermal gradient in the Western U.S.
- A diagnostic fracture injection test was completed successfully, indicating the formation can be stimulated and providing key reservoir data for development planning.
- The reservoir sits in sedimentary rocks—sandstones, claystones, and carbonates—expanding Fervo’s EGS targets and suggesting simpler, more cost‑effective drilling than granite.
- Fervo credits proprietary AI‑driven subsurface analytics and AI‑enabled drilling with identifying and optimizing the Blanford play.
- The findings were presented by Co‑Founder and CTO Dr. Jack Norbeck at the 51st Stanford Geothermal Workshop, with industry outlets reporting the company’s results and the cited independent assessment.
