Fervo Energy Cuts Drilling Time by 70% with Third-Generation Well Design
Event summary
- Fervo Energy drilled Sawtooth 7, its ninth well using the 3.0 design at Cape Station Phase II, in 21 days.
- The well reached a measured depth of 19,448 feet with a 7,500-foot lateral in a 460°F resource.
- Drilling time reduced by 70% compared to the first commercial horizontal well at Project Red in 2022.
- Cape Phase II is on track to deliver power at $5,500 per kilowatt, with a goal of achieving $3,000 per kilowatt.
The big picture
Fervo Energy's latest drilling milestone underscores the strategic importance of learning curves in enhancing geothermal productivity. The company's ability to reduce drilling time by 70% while increasing well complexity highlights a critical shift in operational efficiency, potentially lowering costs and improving project economics. This development aligns with broader industry trends toward cleaner, more reliable energy solutions, particularly as demand from AI hyperscalers and utilities grows.
