Monthly Dinner Meeting
Thursday, May 4, 2017
Speaker: Dr. Bridget Ayling
Topic: Engineered Geothermal Systems: The Habanero Project (Australia) and the Fallon FORGE project (USA)

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 1970’s, 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 present an overview of the Habanero EGS project in the Cooper Basin, central Australia. Managed and developed by Geodynamics Limited, the Habanero project was one of the deepest, hottest and most challenging EGS sites developed anywhere in the world to date, and was operated as an active test site from 2002 to 2015. I will also introduce the US Department of Energy’s FORGE initiative (Frontier Observatory for Research in Geothermal Energy) and the Fallon FORGE site in Nevada. Currently in Phase 2, FORGE aims to develop a site for the testing and development of EGS technologies. I will provide an update of activities at the Fallon FORGE site.

Bio: Dr. Bridget Ayling completed a PhD in paleoclimate and environmental geochemistry at the Australian National University in 2006, after which she began working at Geoscience Australia (Australia’s national geological survey). Dr. Ayling worked at Geoscience Australia for 10 years, including a 2-year secondment to the Energy and Geoscience Institute at the University of Utah. During her time with Geoscience Australia, she worked in both conventional and unconventional (i.e. Engineered Geothermal Systems [EGS]) geothermal settings in Australia and the USA, conducting regional geothermal resource assessments, surface heat-flow measurements, aqueous geochemistry studies, reservoir characterization, geochemical tracer studies, and numerical modelling to understand reservoir fluid flow regimes. Dr. Ayling joined the Nevada Bureau of Mines and Geology and the College of Science at the University of Nevada, Reno in 2016 as an Associate Professor and new Director of the Great Basin Center for Geothermal Energy. Her current activities include teaching, managing the National Geothermal Academy and the GBCGE, conducting research, outreach, and contributing to the Fallon FORGE project.

Geography 2017 Spring Colloquium Series—April 26:

Mike DettingerARKStorm@Tahoe – Science and Societal Impacts
“Risk and Hazards”
Every Wednesday, 4 to 5 p.m.
Mackay Science, Room 321
Parking at UNR

WHEN: April 26
WHO: Mike Dettinger, U.S. Geological Survey
TOPIC: ARKStorm@Tahoe – science and societal impacts

UNR Arboretum “Tree Talk” Series—April 25:

Charlie TruettnerTrees, Drought, and Climate Change in the American Southwest
Tuesday, April 25, 7:00 PM, William Raggio Building, Room 2003
Parking at UNR
Sponsored by the Arboretum Board at UNR

Charlie’s talk will combine science and story centered on his experiences as a graduate student and professional in the deserts of the American Southwest.  Conifers located on top of desert sky islands have and are experiencing mortality events like no other in modern history.  Through the use of dendrochronological and paleoecological methods, Charlie interprets trends of conifer tree species from the past to help understand projected vegetation change over the 21st century.

Charlie is a PhD student in Dr. Franco Biondi’s DendroLab and the Geography Department at UNR.  He received his M.Sc. in Quaternary Science at Northern Arizona University, and he has worked for or collaborated with the National Park Service, United States Geological Survey, Merriam-Powell Center for Environmental Research, National Science Foundation, and many other academic institutions in the American Southwest.

Nevada Mineral and Energy Resource Exploration Survey 2015/2016

Authors: Michael W. Ressel and David A. Davis
Year: 2017
Series: Exploration Survey ES-2016
Version: previously issued as “Nevada Exploration Survey” by Nevada Division of Minerals; second issue of the new NBMG series
Format: 16 pages, color
Download/purchase here.

The Nevada Bureau of Mines and Geology (NBMG) carried out an online survey of companies exploring for new metal, industrial mineral, and geothermal resources in Nevada. The Nevada Commission on Mineral Resources and the Nevada Division of Minerals commissioned and provided partial support for the survey. The impact of mineral and energy production from existing resources on the Nevada economy is well known. However, the impact of exploration activities, which focus on discovering new resources, is poorly understood due to limited data. Exploration activities are burdened with high risk as substantial investments are not guaranteed to result in mineable resources. Indeed, only rarely do exploration programs result in successful resource extraction, and then only after many years of capital investment and development activities. Despite this, exploration success is imperative for the continued well-being and sustainability of natural resource industries in Nevada.

A goal of this survey was to gather data to better assess the impact of exploration on Nevada’s economy. The survey’s focus was to collect data on company expenditures in Nevada and the number of employees involved in exploration in 2015 and 2016. Expenditures were subdivided by various categories and participants were asked to rate the relative importance of external factors on their exploration programs. The survey requested participation from 296 companies presumed to explore for mineral and geothermal resources in the state. Of these, responses from 86 companies were obtained, another 23 responded that they no longer explored in Nevada, and 54 non-responding companies were researched using public domain sources for their 2015 and 2016 Nevada expenditures.

The results verify that Nevada exploration activities were substantially curtailed as a result of the continued global decline in commodity prices since peak activity during 2011–2012, when the last survey was undertaken. Major findings are included in this publication.
