Drilling Ordeals Said to Delay Geothermal Project

The bit has snapped off at least once and become repeatedly fouled in a shallow formation called cap rock, and the drillers have twice been forced to pull it out and essentially start the hole over again.

Late last year, the project, undertaken by a start-up company called AltaRock Energy, received $6.25 million in financing from the Energy Department, in hopes that it would be the first of dozens of projects to produce renewable energy by fracturing rock at the bottom of a deep hole and then circulating water through the cracks to generate steam.

But last month, after an article in The New York Times raised questions on whether AltaRock had been forthcoming about earthquakes generated by a similar project in Basel, Switzerland, the Energy Department and the Bureau of Land Management informed the company that it would not be allowed to fracture rock until the department completed a new review of whether the project would be safe. The company was allowed to keep drilling, however, down toward the depth at which it would begin the fracturing.
