Stimulation underway at the Newberry EGS project in Oregon
Stimulation going forward and other updates have been released for the the Newberry EGS project in Oregon, successfully injectong approximately 3,000,000 gallons of water into the expanding EGS reservoir
Newberry EGS Demonstration injection well project has published some new developments in their website. The following is the press release done by the company.
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.
Over the next week, we’ll inject TZIM into the well, diverting water flow away from the current zone and forcing it out into other areas to further improve the reservoir. After stimulation is complete, TZIM will biodegrade leaving behind an interconnected, multi-zone EGS reservoir. Once the TZIM has biodegraded, the well will be flow tested; steam and water production and temperature will be recorded and used to analyze results of this year’s field work.
We’d like to extend a thank you to all those who participated in the Geothermal Resource Council’s Newberry EGS Demonstration site tour in late September. We had a great day in the field showing you the project site, and look forward to seeing you again soon! We also had a great weekend talking to visitors who stopped by our booth at the Bend Fall Festival last weekend.
