Geothermal Dual Acoustic Tool for Measurement of Rock Stress

The current hydrothermal power generation is about 1/2% of total US electricity demand, which is small compared to the potential geothermal power that could be developed using Enhanced Geothermal Systems (EGS). EGS depends on creating or enhancing a geothermal reservoir by well stimulation in a hot rock formation. The acoustic (or sonic) tool Perma Works is developing will measure the directional permeability of water and stress in potential geothermal formations. This will greatly reduce the cost of identifying and developing potential EGS fields eliminating the mini hydro-fracturing procedure to determine relative permeability and stress. As Perma Works is a leader in high-temperature electronics for logging tools, Perma Works has partnered with RelChip. RelChip is a manufacturer of the first & gt;250C operating 32Bit, ARM7 microprocessor. Not only will the proposed logging tool measure directional rock stress but it will run on conventional geothermal logging equipment and be able to stay in the well for indefinite periods of time
