WebFault slip during the hydroshearing experiments was predominantly aseismic. The results of our hydraulic stimulations indicate that stimulation of short borehole intervals with limited fluid volumes (i.e., the concept of zonal insulation) may be an effective approach to limit induced seismic hazard if highly seismogenic structures can be avoided.

Web7 feb. 2024 · Open fractures in hydroshearing are formed at relatively low pressures because their strength is lower than that of the surrounding rock. Pumping pressure that is too high can “overstimulate” HDR formation, causing irreversible rock movements and leading to a short circuit (e.g., Rosemanowes, Fjalbacka) [ 4 ]. Webhe Seattle - Geothermal energy developers plan to pump 24 million gallons of water into the side of a dormant volcano in Oregon to demonstrate new technology they hope will give a boost to a green energy sector that has yet to live up to its promise.
