NPGS Monthly Dinner Meeting: Dixie Valley Geothermal Power Project—September 3, 2015      

NPGS logo

What: Nevada Petroleum & Geothermal Society—Monthly Dinner Meeting
When: Thursday, Sep 3, 2015
Where: Ramada Reno Hotel, 1000 East 6th Street, Reno, NV
Speaker: Dick Benoit, Consulting Geothermal Geologist, Reno, NV
Topic: Dixie Valley Geothermal Power Project

Abstract: The 56 MW net Dixie Valley geothermal power project has now operated at more or less full output for 27 years. This success was primarily due to three companies with very different character and strengths being involved during the development phase between 1974 and 1988. The wide spacing of exploration wells early in the project history greatly reduced dry hole or step-out risk during the field development phase. The large horizontal and vertical separation between producers and injectors has been successful in allowing modest production fluid temperature declines. The project evolved over its initial 9 years of production from a 49.8 MW net project with a projected long-term production well makeup schedule to a 56 MW net project supported by a cold groundwater injection augmentation program that stabilized the reservoir pressure and eliminated the need for future makeup production wells. The timing of this fairly intense and costly activity coincided with a period of high electricity prices in the Standard Offer #4 contract that allowed significant ongoing field development expenditures. Since 2000 project improvements have shifted from the wellfield to power plant modifications. The turbine was modified to enable the power plant to operate at lower pressures and a 5 MW net binary plant was installed on the injection line.

About the speaker: Dick Benoit is a semi-retired consulting geothermal geologist with 42 years of work in the geothermal industry. He has a Bachelors degree in geology from Western Washington University in 1970 and a Masters degree in geology from the University of Montana in 1972.  Dick began working in the geothermal industry in 1973. He was the Resource Manager of the Dixie Valley geothermal field from 1986 until 2000.

Nevada Today Article—Cutting-Edge Geothermal Research at UNR

Forging new geothermal resources through research: U.S. Department of Energy project calls on University expertise in geologic modeling and geothermal exploration

8/5/2015 – By: John Seelmeyer, Nevada Today

http://www.unr.edu/nevada-today/news/2015/forging-new-geothermal-resources-through-research

RENO, Nev. – Researchers from the University of Nevada, Reno are poised to play a key role in a project that holds the potential to unlock massive new resources of power generated from geothermal sources.

The project dubbed “FORGE” – short for Frontier Observatory for Research in Geothermal Energy – seeks to dramatically widen the number of potential locations where power could be produced from geothermal resources. University professors Jim Faulds and Wendy Calvin, among the world’s leaders in the understanding of geothermal systems, are providing their expertise to the project funded by the U.S. Department of Energy.

Researchers from the University will provide geologic modeling of two potential FORGE sites – one near Fallon and a second near Coso, California. This geologic modeling is critically important to the FORGE project, Faulds, director of the University’s Nevada Bureau of Mines and Geology, explained. “The feasibility studies will help determine where best to establish the FORGE project.”

The establishment of FORGE at these two sites will provide the geothermal community a field laboratory where the science and engineering needed for widespread commercialization of EGS, enhanced geothermal systems, can be developed and refined.

Traditionally, geothermal power plants have been built at locations where they could tap into a naturally occurring source of steam heated under the earth’s surface. After the hot water is used to generate power, it is re-injected back into the earth and re-heated to be used again and again.

The FORGE project, however, seeks to develop enhanced geothermal technology for use at locations where heat is available but water doesn’t naturally flow through the underground rock. Those locations are widespread through the Great Basin.

“The potential is enormous,” Faulds said. The Department of Energy, which is funding the FORGE program, estimates that enhanced geothermal systems could power 100 million homes in American with clean and renewable energy.

But the geological challenges are difficult, he said, because researchers need to find ways to open formations sufficiently so that water can move through the heated rock and become steam to drive generating units.

“We know that there are huge resources in the subsurface,” the geologist said. “Finding that fluid flow is the trickiest part.”

The researchers based in the University’s College of Science bring valuable experience to the FORGE team: experience that will make that job easier.

“We have a long history of working with the geothermal systems in the region and understanding the geologic setting of those systems,” Faulds said.

Participation in the FORGE project provides an opportunity for University researchers to widen their knowledge of geothermal operations and maintain the state’s position on the cutting edge of development of the geothermal industry.

“FORGE will lay the groundwork for new methods, expand our exploration from surface to the subsurface and allow us to include new projects in reservoir modeling and 3D data synthesis,” said Calvin, a professor in geophysics and remote sensing who serves as director of the Great Basin Center for Geothermal Energy [gbcge.org] headquartered at the University.

The program also draws the spotlight to other University research.

“The FORGE project offers the University and the State of Nevada a huge opportunity to showcase our cutting-edge research capability in enhanced geothermal systems,” said Mridul Gautam, the University’s vice president for research and innovation. “I thank the Department of Energy for recognizing the leadership and commitment demonstrated by this University and the state to advanced research and development of clean-energy technologies, in general, and geothermal energy, in particular.”

The two FORGE projects in which the University was selected to participate are among five sites under analysis that will share $2 million in Department of Energy funding.

In this first phase of the project, researchers will examine the feasibility of each of the five sites. Up to three of the sites then will be selected for further research, totaling up to $29 million, during the next two years. From that second phase work, one site will be selected for FORGE research and development.

Sandia National Laboratories is leading both FORGE research teams in which the University is participating. Other key partners in both the Fallon and Coso research include Lawrence Berkeley National Laboratory, U.S. Geological Survey, GeothermEx/Schlumberger, the U.S. Navy and Itasca Consulting Group.

In the Fallon project, Ormat Nevada, Inc. of Reno is a key partner. In the Coso project, the Coso Operating Company LLC is a key partner.

New Server for NBMG Website—please note new links

The NBMG website has been moved to a new web server. This web server migration was critical since the old server was running the Microsoft Server 2003 operating system, which becomes unsupported on July 14, 2015.

The URLs have changed for the “Free Downloads” links on the Publications page, so please be sure to update your bookmarks. Here is an example of the new URL format (for Nevada Mineral Industry 2013):

Old URL: http://www.nbmg.unr.edu/freedownloads/mi/mi2013.zip  (no longer works)
New URL: http://data.nbmg.unr.edu/public/freedownloads/mi/mi2013.zip

You can locate these Free Downloads links by clicking on the blue publication title on the listing of NBMG publications on the shopping cart. When you click on the title, you will then be on the publication landing page which includes options to purchase the item or download it for free if that option is available. If there is no Free Downloads tab to the right of the Description tab on the landing page, then there is no free download available. The Description and Free Downloads tabs are located on top of the gray text box under the thumbnail images.

Note that some pages in our website have moved as a result of this server migration, particularly from our cleanup and organization of the web server files in order to make updating the website more efficient. We also had to eliminate php code in order to move our website to the University’s server.

Here are some of the main pages affected by the changes:

There is limited space on the new web server, so to organize our data and ensure there is plenty of room for growth we moved our large static data (mining district scans, historical air photos, etc.) to a new location that includes “http://data.nbmg.unr.edu” in the first part of the URLs. While data.nbmg.unr.edu is not an open server to browse through, all public data that sits at data.nbmg.unr.edu is accessible through links in various web pages throughout our website and interactive web applications.

If you have any questions about this migration, please contact Jennifer Vlcan, Manager, NBMG Cartography & GIS group

New Geologic Map—Welcome Quadrangle

Welcome

Title:  Geologic map of the Welcome quadrangle and an adjacent part of the Wells quadrangle, Elko County, Nevada
Author:  Allen J. McGrew[udayton.edu] and Arthur W. Snoke[uwyo.edu]
Year:  2015
Series:  Map 184
Format:  plate: 51 x 32.5 inches, color; text: 40 pages, color
Scale:  1:24,000; inset: 1:12,000

Located in central Elko County, the Welcome quadrangle and an adjacent part of the Wells quadrangle expose a remarkable array of critical relationships for understanding the geologic history of the state of Nevada and the interior of the southwestern U.S. Cordillera. Covering the northern end of the East Humboldt Range and adjacent Clover Valley and Clover Hill, this map includes the northern terminus of the Ruby Mountains–East Humboldt Range metamorphic core complex.

The oldest rocks in the state of Nevada (the gneiss complex of Angel Lake), and Nevada’s only exposures of Archean rock, form the core of a multi-kilometer scale, southward-closing recumbent fold-nappe, the Winchell Lake nappe (WLN). Although intensely metamorphosed and profoundly ductilely attenuated, the WLN folds a series of pre-metamorphic thrust allochthons that collectively form an essentially complete sequence of Paleoproterozoic to Mississippian metasedimentary rocks. The WLN transported what may be Nevada’s most deeply exhumed rocks, with peak pressures ranging to 10 kb, peak temperatures in excess of 750 ºC, and widespread partial melting and stromatic migmatization, all related to Late Cretaceous to Paleocene tectonism.

Overprinting the metamorphic core is a WNW-directed kilometer-scale shear zone that, together with the detachment fault that forms its roof, accommodated tens of kilometers of extensional displacement in mid- to late Cenozoic time, diachronously exhuming the terrain from mid-crustal depths by late Miocene time. In addition, the high-grade rocks are extensively intruded by one of the Nevada’s most diverse suites of magmatic rocks, ranging in age from Archean to Miocene and in composition from mafic to felsic. On the west flank of Clover Hill, a west-dipping detachment-fault system separates the high-grade metamorphic core from an overlying plexus of brittlely deformed, partly correlative but lower grade to non-metamorphosed Paleozoic rocks. In turn, a sequence of partly syntectonic volcanic and sedimentary rocks ranging in age from Eocene to Miocene structurally overlie the fault-bounded Paleozoic units. The Cenozoic sequence includes late Eocene and Oligocene ignimbrites and volcaniclastic rocks, Miocene sedimentary rocks and megabreccias, a Miocene rhyolite complex, and younger sedimentary rocks and vitric tuffs. The presence of the most distal northeasterly exposure of a key Oligocene volcanic marker, the 29 Ma tuff of Campbell Creek, suggests that a broad, low-relief (unfaulted) terrain was dissected by paleovalleys that extended at least 200 km to the west. Bracketed between the tuff of Campbell Creek and a 15.5 Ma tuffaceous sandstone at the base of the Miocene Humboldt Formation is a proximal sedimentary sequence known as the sedimentary sequence of Clover Creek that includes conglomerate, sedimentary breccia, sandstone, and megabreccia as well as intercalations of fossiliferous lacustrine strata. The megabreccias consist of unmetamorphosed mid-Paleozoic rocks (chiefly Upper Devonian Guilmette Formation) interpreted as rock-avalanche deposits shed from evolving normal-fault scarps inferred to have bounded the basin to the east. Disconformably overlying the sedimentary sequence of Clover Creek is a thick sequence of Miocene Humboldt Formation that is tilted steeply down against the detachment fault system, documenting large-scale displacement on the detachment system extending to at least as young ca. 9 Ma.

Finally, bounding the range today on both east and west are large, normal-fault systems that were active in Quaternary time, including the Clover Hill fault, which may represent a southerly extension of the blind fault that caused the 2008 Mw 6.0 Wells earthquake.

This map was prepared with support from the Geological Society of Nevada; National Science Foundation; University of Wyoming, Laramie; and the University of Dayton, Dayton, Ohio.
