NPGS Monthly Dinner Meeting—Thursday, October 4

Nevada Petroleum and Geothermal Society (NPGS)
Monthly Dinner Meeting
Thursday, October 4
Speaker: Jim Faulds
Topic: Geothermal Journeys through New Zealand and Nevada: Similarities and Differences in Geothermal Activity between Magmatic and Non-Magmatic Rifts


A message from NPGS: Please join us on Thursday, October 4, 2018 at the Tamarack Junction for cocktails, dinner and lecture by Jim Faulds on “Geothermal Journeys through New Zealand and Nevada: Similarities and Differences in Geothermal Activity between Magmatic and Non-Magmatic Rifts.”

Bio: Jim Faulds is the Nevada State Geologist, Director of the Nevada Bureau of Mines and Geology (NBMG), and Professor at the University of Nevada, Reno (UNR). NBMG is a research and public service unit of UNR and is the state geological survey of Nevada. Faulds is a structural geologist with 30+ years of experience. He has been with UNR and NBMG since 1997, first as Professor and then serving as NBMG Director since 2012. He earned his B.S. at the University of Montana, M.S. at the University of Arizona, and Ph.D. at the University of New Mexico. He has studied crustal deformation in many parts of the world, including much of the western U.S., western Turkey, and New Zealand. His research has focused on how fault systems initiate and evolve through time. In recent years, he has been analyzing the structural controls and exploration strategies of geothermal systems in the western U.S., Turkey, New Zealand, and elsewhere. He recently returned from sabbatical in New Zealand, where he worked with GNS Science and the University of Canterbury. At Canterbury, he held an Erskine Teaching Fellowship. He has published over 100 papers and dozens of geologic maps on extensional and strike-slip tectonics, as well as the structural controls on geothermal activity. He has also taught courses in structural geology, tectonics, geothermal exploration, and field geology, while serving as advisor for more than 25 graduate students.

Abstract: The Taupo Volcanic Zone (TVZ) in New Zealand and Great Basin region, USA, represent two premier geothermal provinces on Earth. Both reside in extensional to transtensional settings. The TVZ occupies a dynamic intra-arc rift setting with relatively high rates of extension and voluminous volcanism. The Great Basin region is part of the Basin and Range province and characterized by relatively modest rates of extension and sparse volcanism. Recent magmatism provides heat for many geothermal systems in the TVZ and generates temperatures locally in excess of 300ºC. In contrast, the Great Basin is characterized by non-magmatic geothermal systems with temperatures generally less than 225ºC.

In the Great Basin, nearly 90% of geothermal systems are controlled by four major structural settings: 1) normal fault step-overs or relay ramps; 2) terminations of major normal faults; 3) fault intersections; and 4) accommodation zones. Notably, ~39% of known geothermal systems are blind with no surface hot springs or fumaroles, with estimates suggesting that 75% of geothermal resources are blind. Many blind systems are hidden in basins and obscured by young sediments. Play fairway analysis, whereby multiple geologic and geophysical parameters are combined to identify highly prospective area, holds significant promise of identifying new geothermal systems and reducing the risks of geothermal exploration in this region. This methodology recently resulted in discovery of at least one new blind system.

In the TVZ, similar structural settings (normal fault step-overs, fault tips, and accommodation zones) have been documented for many geothermal fields. Such settings may generally be less impactful, however, in areas of recent magmatism. Structural settings are obscured for some robust systems (e.g. Rotokawa and Wai-O-Tapu) by young volcanic deposits. Active magmatism also produces a suite of additional favorable settings, including dike tips and intersections between normal faults and caldera margins. Blind systems may be relatively common in the TVZ, with impermeable clay caps and thick permeable volcanic deposits at depth precluding venting of some systems. Preliminary maps of favorable structural settings serve as a proxy for potential blind systems in the TVZ. Play fairway analysis, incorporating multiple geologic and geophysical parameters, may ultimately facilitate discovery of new geothermal systems in the TVZ.

Physics Today Article—Bridget Ayling Discusses EGS Potential

Bridget Ayling, Director of the Great Basin Center for Geothermal Energy and Associate Professor, Nevada Bureau of Mines and Geology, was interviewed for this article in Physics Today.

Engineered Geothermal Systems Have Wide Potential as a Renewable Energy Source

Physics Today 71, 9, 22 (2018); https://doi.org/10.1063/PT.3.4017
“What will it take to put geothermal energy to use on a large scale? Iceland uses it nearly exclusively for heat and hot water and for about a fifth of its electricity (see related story on page 26). Many countries have geothermal projects. But the vast stores of heat deep beneath Earth’s surface remain largely untapped. “If we can unlock the technologies to make extracting heat in the subsurface technically and commercially viable on a large scale, the promise is huge,” says Bridget Ayling, director of the Great Basin Center for Geothermal Energy at the University of Nevada, Reno. That’s why, she adds, “despite only incremental gains over the last 40 years, the geothermal community continues to pursue engineered geothermal systems,” or EGS, also known as enhanced geothermal systems.” –from Physics Today 71, 9, 22 (2018)

Nevada Petroleum and Geothermal Society Monthly Dinner Meeting: Thursday, March 1, 2018


SPEAKER:
  Emma McConville, Graduate Student, Geologist, UNR, Reno, NV
TOPIC:  Applications of the Play Fairway Analysis for Geothermal Systems in Crescent Valley, Eureka County, Nevada
ABSTRACT: Crescent Valley received one of the highest favorability scores in phase I of the DOE-sponsored Nevada play fairway analysis project and was therefore selected for detailed study in phase II. As part of the detailed study, geological, geochemical, and geophysical data were collected, synthesized, and analyzed to identify favorable structural settings for geothermal fluids in the basin. A total of nine favorable structural settings were identified. Two host known geothermal systems, and six could potentially host blind geothermal systems. In phase II a predictive geothermal potential model was conducted for each favorable structural setting. The highest-ranking areas in Crescent Valley are in the Dann Hot Springs step-over (relay ramp), followed by the two northern step-overs along the Cortez Mountains front, as well as a fault intersection at Hot Springs Point.

BIO: Emma McConville – Graduate Student, Geologist – UNR, Reno, NV
Emma was born in Barcelona, Spain and grew up throughout Latin America. When she was twelve years old she visited El Tatio Geysers in Chile and immediately became fascinated with geothermal energy and energy policy. In 2012 her interests landed her at Claremont McKenna College in Claremont, CA, where she double majored and earned a B.A. in Economics and Philosophy, Politics, and Economics (PPE). After college, she worked at Endeavor Mexico as a Fulbright Scholar where she started the Endeavor Investor Network and coordinated the largest international private investment event in Mexico to date. Emma had the opportunity to explore the corners of Mexico and her travels reignited her love of the outdoors and geology. In 2013 she decided to refocus her career path and become a geologist. Emma earned a B.S. from the University of Maryland in College Park, MD where she was chosen to be the student speaker for the commencement ceremony for the College of Computer, Mathematical, and Natural Sciences. During her time at the University of Maryland she interned at the Geothermal Energy Association, was awarded the NAGT-USGS internship in Menlo Park, CA, and was the coordinator of Girls Excelling in Math and Science, an afternoon program geared towards encouraging middle school girls to take an interest in STEM. In 2016, Emma began her graduate studies under the guidance of Jim Faulds and plans to earn her M.Sc. in Geology this upcoming summer. Emma has been offered a position as a geologist at ExxonMobil and will be moving to Houston, TX after completing her studies.

SPEAKERS:  John Menghini, BLM, Reno, NV and Lowell Price, NDOM, Carson City, NV
TOPIC:  “State-of-the-State: An Update on Geothermal, Dissolved Minerals (Lithium in Brine), and Oil & Gas Exploration and Development in Nevada”

Please join us on Monday, February 5 2018 at the Tamarack Junction for a State of the State presentation. Lowell Price with Nevada Division of Minerals and John Menghini from the BLM Nevada State Office will discuss oil, gas and geothermal issues in the Silver State.

John MenghiniUS DOI Bureau of Land Management, Nevada Oil and Gas Program Lead.  John has worked in the Nevada State Office, Reno Nevada since 2003.  He provides oversight for all oil and gas operations and technical expertise for all fluid-related development in the state of Nevada.  John is involved not only with the oil and gas program, but as a technical operations specialist for the Geothermal Program.  He has a wide range of knowledge with all aspects of the federal requirements dealing with permitting and unitization agreements including lease suspensions, unavoidable delay requests, paying well determination and establishment/revisions of participating areas.  Because of the limited size of Nevada’s oil and gas program, he is involved in every aspect of the development and support of the fluids program for all District Offices in Nevada.

John graduated from the University of Wyoming with a BS in Petroleum Engineering.  After working a few years in the oil and gas industry, John decided that a little business knowledge would be helpful.  John returned to University of Wyoming, where he graduated with his second degree in Business Management.  John then went to work for the BLM in 1989 in Rawlins, Wyoming as a staff Petroleum Engineer.  In 1993, John transferred to Casper where he worked for the Reservoir Management Group in units and drainage.  In 1995 he moved to the Platte River Resource Area as the Lead Petroleum Engineer for that office.  Later this office became the Casper District, and John stayed there until his move to the Nevada State Office in 2003, where he has worked since that time. John will have 29 years in with the BLM this February.

DGSE Seminar Series—Monday September 11:

DGSE Seminar SeriesMonday September 11:
Engineered Geothermal Systems and the Fallon FORGE Project
Dr. Bridget Ayling
Abstract: Engineered Geothermal Systems (EGS) have the potential to significantly contribute to our baseload energy requirements, with over 500 GWe of resource potential estimated for the western USA alone (USGS, 2008). After the first R&D project to test the EGS concept was initiated at Fenton Hill (New Mexico) in the 1970s, there have been several projects in the USA and internationally that aimed to evaluate the viability of EGS and progress the technologies required to make EGS economic. The key technical challenges associated with EGS center on creating and maintaining appropriate reservoir heat-exchange networks, while managing any induced seismicity associated with stimulation of the reservoir.

In this talk, I will introduce the US Department of Energy’s FORGE initiative (Frontier Observatory for Research in Geothermal Energy) that aims to develop a site for the testing and development of EGS technologies. I will also present an overview of the progress to date at the Fallon FORGE site in Nevada, and upcoming activities planned for the project.
