Short summary
The Newberry Deep Drilling Project (NDDP) will be located on the Newberry Volcano, Oregon, USA, at an idle geothermal exploration well, NWG 46-16, drilled in 2008, 3500 m deep and 340–374 °C at bottom, which will be deepened another 1000 to 1300 m to reach 500 °C. The main goals are to test EGS in the ductile/brittle transition zone and to test technology for drilling, well completion, and geophysical monitoring in a very high temperature environment.
