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.

Stepping Up Outreach for the Fallon FORGE Project

By Bridget Ayling

Members of the Fallon FORGE team staffed a booth at the Fallon Cantaloupe Festival and Country Fair, 24–27th August 2017, to meet the Fallon community and provide them an opportunity to meet us, ask questions and learn more about the Fallon FORGE project. The booth was a success: we spoke with many locals and visitors to the region, and the majority were interested to learn more about our activities and are supportive of the project going forward. We also attracted the younger generation via our swag options (drink bottles, etc.), geothermal core samples borrowed from NBMG’s core facility (the Great Basin Science Sample and Records Library), and a microscope set-up with petrographic thin sections available for viewing. Outreach activities for the Fallon FORGE project are ongoing, and will become increasingly important if the project makes it into the next phase of the FORGE initiative—this will be determined in spring/summer 2018.

NPGS Monthly Dinner Meeting—Sept 7

Nevada Petroleum & Geothermal Society
Monthly Dinner Meeting
Thursday, Sep 7, 2017
Subject: The Shell Oil “Vilche” Deep Test and a Better Understanding of the Pine Creek Fault, Northern Sacramento Basin: What a Difference One Micropaleontology Report Makes!
Speaker: Scott T. Hector, Geologist, Hobby Energy, Rio Vista, CA

Abstract: The Shell Oil “Vilche” well was drilled to a total depth of 19,670’ in 1980.  It is by far the deepest well ever drilled in the Sacramento Basin, even though the deep dry hole is located in the far northern portion of the basin and lies north of any natural gas production.  Recent remapping of this part of the basin, making use of a micropaleontology report of the well, has caused a significant change in the understanding of this part of the basin.  These data, along with data from a 15-well drilling program by Hamar Associates and the Nahabedian Exploration Group between 1998 and 2006, show that the Pine Creek fault has a much larger offset than was previously thought.  The data also show that a thick section of Upper Cretaceous strata was preserved in a “sub-basin” on the northern side of the fault.

Bio: Scott Hector is a partner in Hobby Energy, a geological consulting firm located in Rio Vista, California. The company was started in 2005 with the help of the late Kevin Graham, who also owned Paul Graham Drilling and Service Company. Hobby assists other companies in oil and gas prospect analysis, drilling proposals and mineral remoteness opinions. In recent years most of the work for the firm has been the Mineral Remoteness Opinions, mainly for the solar power and wind power industries.

Scott was born in 1948 in Albany, California. He has been interested in geology since he burned his hand trying to pick up a sparkly gravel rock in the parking lot of a restaurant near Palm Springs in the middle of summer at the age of 5. His father bought him a small child’s rock collection in the restaurant to stop his crying. He fell in love with the collection, even sleeping with it, according to his parents. The love affair has never ended!

Scott attended Humboldt State College from 1967 to 1970, but transferred to the University of California at Davis. He received his B.S. degree in Geology from there in 1972, and his M.S. degree from UCD in 1976. He actually started to work in the oil industry with Texaco in 1974, and finished his thesis two years later. His thesis was a mapping thesis over the Castle Rock Quadrangle in the Santa Cruz Mountains, some 40 miles south of San Francisco on the Peninsula (and, where he grew up on a 200-acre ranch). Scott had Robert Matthews and Cordell Durrell from UCD on his committee, and Dr. Earl Brabb from the USGS.

So, Scott’s oil patch experience has been over 40 years. He has held between 12 and 14 jobs, depending how you count “ungainful employment as a consultant”. Work places have been Los Angeles, Bakersfield, Woodland, Davis, Houston, Denver. Employers have included Texaco, Carlsberg Petroleum, Great Basins, Champlin, MCOR (McCulloch), Energylog, North Valley, Gary Drilling, Gotland Oil, Carneros Energy and Hobby Energy. Areas of work have included oil or gas fields throughout the U.S.A., but mainly in the basins of California and the Paradox Basin of Utah and Colorado.

The paper presented today is due to work that Scott is doing for the Pacific Section AAPG. The group is planning to publish a C.D. on geological contributions on the Sacramento Basin. Scott started to work on a paper on the deepest wells drilled in the basin, and became intrigued with the deepest one. This led to discussions with his great friend Al Almgren, who provided him with paleo data on the deep well. The results of the study will be discussed with the group. The talk was first presented at the join Rocky Mountain AAPG and Pacific Section AAPG meeting in Las Vegas in October 2016.

New Geologic Map—Bradys Geothermal Area, Churchill County

Preliminary Geologic Map of the Bradys Geothermal Area, Churchill County, Nevada
Authors: James E. Faulds, Alan R. Ramelli, Mark F. Coolbaugh, Nicholas H. Hinz, Larry J. Garside, and John H. Queen
Year: 2017
Series: Open-File Report 2017-04
Format: plate: 51 x 39 inches, color, with cross sections; text: 6 pages, color
Scale: 1:12,000

The Bradys geothermal field lies in the northern Hot Springs Mountains ~80 km northeast of Reno in Churchill County, Nevada.  The field has a reservoir temperature of 180-193°C at 1- to 2-km depth and currently supports a combined dual flash and binary geothermal power plant with a total installed capacity of 26 MWe, as well as a vegetable dehydration plant.  The power plant has been in operation since 1992.  The detailed geologic map and cross sections of the Bradys geothermal field illustrate the linkages between permeability and a complex structural setting dominated by a left step in a normal fault zone but also including several fault intersections within a broader accommodation zone.  Seismic reflection data and re-logging of cuttings and core from 34 wells were incorporated into the cross sections.  A previously published 1:24,000-scale geologic map of the Desert Peak quadrangle only included the easternmost part of the Bradys geothermal field.  The purpose of this map is to show the entire geothermal field at a finer scale (1:12,000) sufficient to illustrate multiple geothermal features, such as the complex faulting, sinter, warm ground, and fumaroles.  Unpublished versions of this map and cross sections have served as the foundation for previously published, 3D structural modeling and 3D gravity inversion of the Bradys geothermal field.

This project was supported by the U.S. Department of Energy, Ormat Technologies, Inc., and the U.S. Geological Survey STATEMAP Program.

The Geothermal Technologies Office Announces Play Fairway Analysis Phase III Selections

The Geothermal Technologies Office Announces Play Fairway Analysis Phase III Selections

Release from the US Office of Energy Efficiency & Renewable Energy (July 20, 2017):
https://energy.gov/eere/geothermal/articles/geothermal-technologies-office-announces-play-fairway-analysis-phase-iii

“The U.S. Department of Energy’s Geothermal Technologies Office (GTO) announced it will continue funding for 5 projects aligned with Phase III Play Fairway Analysis (PFA) activities. GTO will award up to $5 million in additional funding to five of the original 11 projects from the 2014 PFA Funding Opportunity Announcement. The awards will address the overarching theme of uncertainty quantification and reduction in geothermal exploration, specifically through the development of Geothermal Play Fairways.

The concept of “play fairway analysis” has been used to identify potential locations of blind hydrothermal systems in the western U.S. A play fairway analysis defines levels of uncertainty with respect to the presence and utility of geothermal system elements, and translates them into maps to high grade the geographic area over which the most favorable combinations of heat, permeability, and fluid are thought to exist. Phase III moves the projects into an exploratory drilling campaign that will test the Phase I and II developed models’ ability to discover new resources. Once identified, hydrothermal resources can be brought online quickly with current technologies, supporting the near-term expansion of renewable energy in America.

This systematic approach early in the exploration process can reduce costly drilling and improve the probability of successfully tapping the vital mix of high temperatures and sufficient water flow necessary to generate electricity from geothermal energy. By improving success rates for exploration drilling, this data-mapping tool will help attract investment in geothermal projects and significantly lower the costs of geothermal energy.

The selected Phase III awardees are:

Nevada Bureau of Mines and Geology, University of Nevada‐Reno – Reno, Nevada
Utah State University – Logan, Utah
University of Hawaii – Honolulu, Hawaii
University of Utah – EGI Great Basin – Salt Lake City, Utah
Washington Division of Geology and Earth Resources – Olympia, Washington”
