We have exciting news to share this morning. Yesterday, we got both pumps running at full capability and brought the well head pressure up to 1800 psi. Shortly afterwards, two microseismic events with magnitudes close to zero occurred near the bottom of the bore hole. In addition, the permeability increased slightly. This means that hydroshearing and creation of an EGS reservoir has begun! As we continue to slowly increase the rpm’s of the pumps, we anticipate many more microseismic events over the next week.
The map above shows the locations (red dots) of the events in relation to the geothermal well’s surface location and five of our closest monitoring stations.
