Announcing Workshop to Plan for Deepening Newberry Well and reach over 450 °C

July 10, 2017

Bend, Oregon, July 10, 2017: The NEWGEN consortium is pleased to announce that an international workshop of geoscience experts will be held this fall to develop a full proposal for drilling one of the hottest wells in the world at Newberry Volcano, central Oregon. The workshop will be held at the Oregon State University – Cascades campus in Bend, Oregon from September 10-14, 2017.

Important scientific questions related to volcanic hazards and geothermal energy will be discussed by more than 40 engineers and scientists during this workshop sponsored by the International Continental Drilling Program (ICDP). ICDP is a non-profit organization that supports international science teams with a proven need for land-based drilling. While ICDP may partly fund future drilling, an important goal of the workshop is to identify other funding sources interested in contributing to potential economic breakthroughs in geothermal energy production and scientific breakthroughs in earthquake and volcano studies.

The Newberry Geothermal Test Facility is located on the western flank of the caldera rim of Newberry Volcano, one of the largest geothermal heat reservoirs in the western United States, extensively studied for the last 40 years. Here, hot rock is relatively close to the surface, making it easier to drill super-hot wells and carry out enhanced geothermal system (EGS) research. Millions of dollars have already been invested in the site by private geothermal developers and the US Department of Energy, resulting in a ready-to-use facility with the necessary infrastructure, environmental permits, land commitments, and monitoring plans. An idle geothermal exploration well drilled in 2008, already 3500 m deep and 320°C at bottom, will be evaluated for deepening another 1500 m to reach temperatures above 450°C.

The NEWGEN consortium was formed in 2015 by Pacific Northwest National Laboratory, AltaRock Energy, Oregon State University and Statoil to develop a research observatory on geothermal energy on Newberry Volcano. The ICDP workshop was proposed by the NEWGEN team, and other world-renowned scientists and engineers from the United States, Canada, Japan, Norway, Iceland, France, and Italy. Invited participants will have world-class expertise in geothermal energy, drilling at extreme temperatures, seismology, and volcanology.

Dear NEWGEN Supporters,

Dear NEWGEN Supporters,

Today, the Department of Energy announced the site locations for the second phase of the Frontier Observatory for Research in Geothermal Energy (FORGE). Unfortunately, the Newberry site was not selected and our efforts to establish a geothermal field laboratory near Newberry Volcano has come to a close.

We’d like to thank you all for your support. As we embarked on this project, we received tremendous support from the local community, state and local government representatives, and industry partners.

Over the course of a year, a strong working relationship was established between members of the Newberry site proposal team – AltaRock, General Electric, Pacific Northwest National Laboratory, Oregon State University, and Statoil. While the loss of the FORGE opportunity is a setback, the NEWGEN consortium is committed to continuing geothermal research and development at Newberry and will be investigating other funding sources in the near future.

Hello NEWGEN supporters! We write to you today with a brief update on the Frontier Observatory for Research in Geothermal Energy (FORGE). When we talked to many of you at the Bend Summer Festival, the Department of Energy was deliberating to choose three of the original five sites to continue competing for the final round of the FORGE selection.

Unfortunately, this process has been delayed, and we’re now expecting results by the end of September. We eagerly await DOE’s decision, and won’t hesitate to post again when we find out more! Stay tuned.

NEWGEN FORGE Laboratory – A Resource for Graduate Education and Research

August 2, 2016



The internal structure of Newberry Volcano is revealed in slices through a preliminary 3D electrical resistivity model. Warm colors indicate where the earth is conductive, blue resistive.

One of the skills I’ve gained as a graduate student studying geophysics at Oregon State University (OSU) is the ability to visualize miles of solid rock and model the internal structure of volcanoes. This is not easy to do when (aside from a limited number of deep wells) we’re only able to access the earth’s surface. To create an image of the subsurface, we take a variety of surface measurements at hundreds of locations and create a model of the subsurface that reproduces the signals we measured. We assess the performance of the model by comparing synthetic data calculated from the model with observed data. We can use data collected from deep boreholes to directly assess model predictions.

At the Newberry Volcano, we are very fortunate to have an enormous amount of data to constrain our models. There are over 40 years of extensive geophysical and geological surveys, information from four deep wells and numerous boreholes around the Newberry Geothermal Energy (NEWGEN) area. This extensive set of data allows us to create an accurate representation of the subsurface.

Some of the geophysical data used at Newberry come from small variations in the strength of the Earth’s gravity caused by variations in the density of rocks, differences in how fast seismic waves move through different types of rock, how much the ground surface is moved when fluids are injected deep underground, characteristics of tiny earthquakes that have been detected in the area, and how electric current flows through different materials underground. My focus is on the electrical properties of Newberry, where we use a geophysical method called magnetotellurics (MT).

Using MT, we look at the electric current that is induced by small fluctuations in the Earth’s magnetic field. This signal is driven by electric currents in the ionosphere that cause the Aurora borealis and distant lightning strikes, and we measure it using magnetometers along with an extremely sensitive voltmeter with electrodes extending into the subsurface.

Researchers at OSU have developed data processing tools that are used by scientists around the world to create models of the earth’s electrical resistivity, not only at geothermal sites, but also in tectonic studies of continent-scale geologic structures. I use these tools to determine what parts of Newberry are more electrically resistive and more conductive, which tells us about the composition of the subsurface. It is especially sensitive to the presence of fluids that fill permeable areas of the rocks, as well as to the presence of clays and various minerals that may indicate the presence (past or present) of fluids circulating underground. Sensitivity to this kind of target is really important to our goal of locating where the rocks at Newberry are hot and dry.

Comparing models developed using MT data with models derived using complementary measurement techniques (gravity and seismic) allows us to assess the validity of our predictions. General agreement in model predictions between the various techniques increases our confidence in our representation of the site; this high degree of inter-model harmony gives us confidence that jointly interpreting the different types of geophysics results in an accurate model of subsurface rocks and geologic structures, and provides a 3D view of the NEWGEN site without ever leaving the ground surface.

Testing Novel Reservoir Stimulation and Fracture Imaging Methods

June 24, 2016

Creating a well-connected network of fractures in hot, impermeable rocks is central to the performance of enhanced geothermal systems. The amount of heat that can be extracted is directly influenced by several properties, such as reservoir permeability and fracture surface area. Our ability to not only enhance, but also measure those fracture attributes is crucial to a better understanding of geothermal energy production in hot dry rocks.

The Department of Energy Subsurface Technology and Engineering R&D (SubTER) crosscut is currently funding research to explore novel reservoir stimulation approaches combined with methods for real-time imaging of fracture networks. Last month I traveled to Socorro, New Mexico and participated in a targeted field demonstration of this new technology with a team of researchers led by Sandia National Laboratory that included support from Pacific Northwest National Laboratory (PNNL) and Lawrence Berkeley National Laboratory.

A series of stimulation tests were performed using a novel explosive developed by Sandia that is designed to maximize permeability and at the same time minimize unwanted damage to the borehole. In addition, a suite of geophysical (electrical resistivity tomography, cross-borehole seismic, distributed acoustic, and ground penetrating radar) imaging technologies were deployed along with hydraulic tests and injection of signal enhancing contrast agents to characterize the newly developed fracture network. Novel real-time imaging capabilities developed by PNNL were also demonstrated during the integrated test. This technology will help provide critical information for operational control of the fracture generation process in the future, and could be a technology demonstrated at DOE’s Frontier Observatory for Research in Geothermal Energy (FORGE) site.
