The first microseismic events associated with stimulation were recorded on September 28

Stimulation of the Newberry EGS Demonstration injection well, NWG 55-29, began on September 23. Since then, we’ve successfully injected approximately 3,000,000 gallons of water into the expanding EGS reservoir. 

The first microseismic events associated with stimulation were recorded on September 28, and to date over 200 events have been located by the microseismic array (MSA). These events continue to be reviewed by seismologists as data streams in from the field. Data from a number of the MSA stations is available for viewing on the Pacific Northwest Seismic Network  and the Lawrence-Berkeley Nation Laboratory website.
