Fervo says its third-generation well design drills 143% faster than its first Cape Station well
Fervo drilled Sawtooth 7, its ninth well using a third-generation design, to 19,448 feet measured depth with a 7,500-foot horizontal section at 460 degrees in 21 days. That is 143% faster drilling than its first Cape well, with cost targets of $5,500/kW for Phase II.
- Sawtooth 7 reached 19,448 ft measured depth with a 7,500-ft horizontal section at 460°F in 21 days—a 70% reduction in drilling time vs. the first commercial well.
- Third-generation design improvements demonstrate a steep learning curve that could unlock higher output per well and lower per-megawatt costs.
- Cape Phase II targets $5,500/kW with longer-term goals of $3,000/kW, approaching conventional power plant economics.
