| Abstract | The Hotspot project has sampled three different geothermal environments in the Snake River Plain (SRP) in Idaho. The project used slim-hole wire line coring in conjunction with a bottom hole temperature probe developed by DOSECC. The first hole at Kimama in the center of the eastern SRP was cored to a depth of 1,915 m. Temperature measurements showed the SRP fresh water aquifer extends to a depth of 965 m and masks the underlying temperature gradient of 74.5oC/Km. A core hole in the town of Kimberly reached a depth of 1,959 m and demonstrated a resource of >50° C from 800 m to the bottom of the hole. A core hole at Mountain Home AFB in the eastern SRP reached a depth of 1,821 m and documents an intermediate- to hightemperature resource. |
