Enhanced geothermal systems use well stimulation and hydroshearing technology to improve geothermal reservoirs.
The hydroshearing process creates movement and sound in the rock, resulting in microseismicity. The opening and growth of fractures during stimulation is mapped by real-time measurement of the microseismicity. Using a micro-seismic array (MSA), AltaRock’s engineers and geologists closely monitor the stimulation process. Data gathered by the MSA is used to map the fracture network and generate a microseismic event map around the well bore. Micro-seismic event maps reveal the size, location and orientation of the fracture system, and are used to track and quantify reservoir growth.
