Final Project Report: THE SNAKE RIVER GEOTHERMAL DRILLING PROJECT: INNOVATIVE APPROACHES TO GEOTHERMAL EXPLORATION

The goal of our project was to test innova9ve explora9on technologies using exis9ng and new data, and to ground-truth these technologies using slim-hole core technology. The slim-hole core allowed us to understand subsurface stra9graphy and altera9on in detail, and to correlate lithologies observed in core with surface based geophysical studies. Compiled data included geologic maps, volcanic vent distribu9on, structural maps, exis9ng well logs and temperature gradient logs, groundwater temperatures, and geophysical surveys (resis9vity, magne9cs, gravity). New data included high-resolu9on gravity and magne9c surveys, high-resolu9on seismic surveys, three slimhole test wells, borehole wireline logs, lithology logs, water chemistry, altera9on mineralogy, fracture distribu9on, and new thermal gradient measurements.
