Exploration Activity: Slim Holes At Blue Mountain Geothermal Area (Fairbank Engineering Ltd, 2003)

Exploration Activity Details
Location Blue Mountain Geothermal Area
Exploration Technique Slim Holes
Activity Date 2002 - 2004

Usefulness useful
DOE-funding Unknown

 
Exploration Basis
The first geothermal observation test holes were drilled for the DOE's Geothermal Resource Exploration and Definition (GRED) program. The holes were drilled to test areas of projected high temperatures based from temperature gradients in shallow holes and low apparent resistivity anomalies.
 
Notes
Two geothermal slim holes were drilled, Deep Blue No. 1 &2. Deep Blue No. 1 was completed in 2002 and it reached a depth of 672.1 m and a temperature of 144.7°C. Deep Blue No. 2, was drilled and completed in 2004. It reached 1128 m depth and a maximum temperature of 167.5°C. Results from the subsurface information gained from these drill holes indicated reservoir temperatures of around 250°C. These Geothermal observation holes were an important exploration step before utilization of the Blue Mountain Geothermal Area could take place.
