The project is currently in Phase I of III and has received $400,000 in initial funding from the DOE FORGE initiative plus additional investments from partner institutions. Phase I will culminate in a conceptual geologic model detailing the geothermal resource at Newberry Volcano, and a final report and presentation to the DOE FORGE review committee in the spring of 2016. Together, the conceptual geologic model, report and presentation will articulate Newberry’s suitability as the nation’s FORGE site. The five competing groups in Phase I will be down-selected to a maximum of three groups which will continue to Phase II. Phase II will involve further site characterization, team building and planning, followed by down-selection to the final FORGE site which will continue into Phase III. Phase III will involve field site development, well drilling, reservoir stimulation and testing and other competitively funded research and development activities related to EGS.

If Newberry Geothermal Energy is selected as the final FORGE site, there will be significant economic benefits to Central Oregon, the state and the region as scientists and engineers from around the country and the world come to the community to do research. The NEWGEN site is just 28 miles from OSU-Cascades, Oregon State University’s branch campus in Bend, creating opportunities for faculty research, student internships and community engagement. Successful development of the Newberry site into a national laboratory for EGS research will support cutting-edge science and engineering dedicated to bringing geothermal energy online at competitive market rates across the country. The laboratory will also serve as a training site for those entering the sustainable energy workforce.

Eventually, research breakthroughs at FORGE will enable development of the massive geothermal resource on Newberry Volcano with the potential to create up to 300 construction jobs and 100 permanent jobs. In addition, the State of Oregon and Deschutes County will benefit from royalty income generated by the project during Phase III. The technologies to be tested and developed at NEWGEN will be applicable across the many volcanic areas of the western US, opening them up to EGS technology and making a real difference to the national capacity for EGS power generation.

With a long history of investment and research at Newberry, the site is well-aligned with DOE FORGE goals and requirements. Previous research at Newberry has made significant progress in characterizing the geologic and thermal properties of the area and significantly improved our understanding of EGS development in volcanic terrains. The Newberry Geothermal Energy team is dedicated to improving the scientific understanding of EGS development, deployment and effective management to generate sustainable energy for the future.

We thank you for visiting and hope you’ll continue to support us in our efforts to bring A Research Observatory for a Sustainable Future to Central Oregon!

The stimulation injected almost four million gallons of water over 32 days of pressurized pumping. During this time 397 microseismic events were detected by the seismometer array, indicating the depth and volume of the EGS reservoir produced. Biodegradable diverters were injected on two separate occasions during stimulation and resulted in the creation of multiple zones of increased permeability within the reservoir. More information about the diverters, to TIZMs, can be found in our previous blog post (link). Preliminary results from the stimulation were presented at the American Geophysical Union Annual Meeting in December, and the poster summary from the meeting can be found here:  AGU Newberry 2014 Poster. The analysis of the pressure, flow, seismicity and water data will continue over the next few months. The reports generated from the dataset will inform planning, permitting and execution of the next stage of work at Newberry. While data analysis is ongoing, scientific papers are currently being prepared for publication and will be presented at scientific meetings in the near future.

We’re quite happy with the stimulation results and look forward to future work at the Newberry EGS Demonstration site. The blog will be relatively quiet over the winter months, but you can expect more frequent updates in the spring as we gear up for more work at Newberry. In the meantime, here are a few more photos from the field season.

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.

The 15 station microseismic array (MSA) collects real-time microseismic data during stimulation. The data is used to map reservoir growth during stimulation. As a result of the Newberry EGS Demonstration, Newberry Volcano has been the most seismically-monitored volcano in the Cascades Range since 2012, when the MSA was installed.

TZIM, or thermally-degradable zonal isolation material (say that five times fast!), swirls into AltaRock’s injection hopper, or DIVA (diverter injection valve assembly). Biodegradable plastic TZIMs block open fractures in the EGS reservoir, forcing water out into new zones during stimulation.

As part of the Geothermal Resource Council’s Newberry field trip, 24 visiting scientists, government officials, journalists, professors and others interested in geothermal research visited the Newberry EGS Demonstration site in late September just after stimulation began.

Presentation by Susan Petty

Susan’s presentation focused on  our efforts to gather information and data to develop our comprehensive operation plan before engaging in the permitting process and various public outreach campaigns (including this blog!).

She also addressed the timescale of field work at the project site, confirming that the highly anticipated Newberry EGS Demonstration has finally become  reality. Susan also  addressed the effectiveness of the diverters used during stimulation,  showing marked improvements in well permeability and evidence of stimulation/diversion locations from continuous temperature monitoring within the well.

Overall, the stimulation results  presented by Susan were well received at Stanford, and the geothermal community posed many questions  about our diversion practices and the implications it has on performing future EGS stimulations in a cost-effective way.

Presentation by Trenton Cladouhos

Trenton presented further evidence of our success at Newberry, discussing the details of our seismic monitoring during the stimulation. Trenton laid out how monitoring can enhance geosciences and engineering techniques, and he described other procedures essential to the expansion of EGS.

Trenton showed that our improvements to the local seismic network made it possible to detect micro-events. This allowed us to monitor the progress of the stimulation, detecting micro-events previously invisible to existing seismic detection equipment. The locations of over 100 events detected by the network showed that over the course of the stimulation, the diverter caused a shift in the location of the local micro-seismicity. This was further indication of our diversion’s effectiveness.

Finally, Trenton shared some of the lessons we learned regarding EGS seismic monitoring, including how crucial the borehole monitoring stations we installed were to the stimulation. The crowd at Stanford was pleased and amused to learn that even our largest events were barely noticeable on surface stations, which seemed to be more effective at detecting cars and trains than seismicity from EGS.

The obvious question is, “Why is so little attention given to geothermal energy?”

The simple answer is there just aren’t many locations where nature has made geothermal energy easily available. Geothermal energy occurs naturally when water from surface sources like rain water, lakes or aquifers finds its way down through the earth to hot rock formations deep underground. When this water comes in contact with hot rock, hot water and steam may rise to the surface in the form of geysers or hot springs. Some of the better known natural geothermal locations are Yellowstone National Park and The Geysers in Northern California. While these locations make popular tourist attractions, they are also marvelous demonstrations of clean, renewable geothermal energy.

There are, however, many areas within the U.S. where geothermal energy could be used to generate electricity if only there was a way to get hot rock and water together. EGS in these locations could be the answer to our future energy needs.

AltaRock Energy is engaged in the development of new technology and techniques for Enhanced Geothermal Systems, or EGS for short. The concept of Enhanced Geothermal Systems is to create a geothermal reservoir by drilling a well to underground formations of hot rock, and opening natural fractures in the rock by injecting water at high pressure. By injecting water down this well, and circulating the water to similar production wells drilled nearby, the water can absorb heat from the rocks, producing hot water or steam that can be used to generate electricity. Refining EGS technology by identifying and developing natural underground formations where water can reliably flow in large quantities (and be heated to sufficient temperatures) is the real challenge.

The scientists, geologists and engineers at AltaRock Energy are hard at work perfecting Enhanced Geothermal Systems technology.
