Proposed Action


Davenport and AltaRock (Proponents) propose to create an EGS Demonstration Project involving new technology, techniques, and advanced monitoring protocols for the purpose of testing the feasibility and viability of enhanced geothermal systems for renewable energy production.

The Project would utilize an existing well pad and existing deep geothermal well on federal geothermal lease OR40497 held by Davenport Newberry Holdings LLC. Nearby there would be 20 microseismic monitoring stations. All of these sites are on nationalforest system lands. Eleven of the sites would be on federal geothermal leases administered by the BLM, and 9 would be on lands that are administered by USFS (Table 1). If approved, drilling and installation of the downhole microseismic monitoring stations for the Project would begin in early 2012.
