Newberry EGS Demonstration: Phase II Preview
We recently posted a recap of our activities during Phase I of the Newberry Enhanced Geothermal Systems Demonstration.
Now that the Bureau of Land Management has issued a Finding of No Significant Impact for the project, we are moving into Phase II activities.
The primary objective of Phase II is the creation an EGS reservoir by using hydroshearing techniques to stimulate an existing deep hot well, NWG 55-29. In doing so, we hope to demonstrate that the underlying heat resource can be efficiently extracted at a rate that is economically viable.
This summer, Phase II tasks revolve around stimulating the existing well, NWG 55-29, and monitoring EGS reservoir creation:
- Three new monitoring wells will be drilled and two existing wells deepened,
- Fifteen seismometers will be installed in the wells and at surface location to create a sensitive real-time seismic network,
- Water supply pipelines and transfer pumps will be configured,
- Stimulation pumps will be brought to the well site,
- Culminating in stimulation and testing of the target injection well in the fall.
Next summer, we will drill and test two production wells to intersect EGS reservoir created this fall. This will be followed by a 30-day circulation test involving the injection well and both production wells.
Throughout this project, we are working with geothermal academics and experts in the geothermal industry to develop, validate and enhance geoscience and engineering techniques. Successful development will provide clean, renewable, baseload geothermal power generation in the State of Oregon and will demonstrate to the American public that EGS can play a significant role in reducing foreign energy dependence.
