Nevada Petroleum & Geothermal Society Monthly Dinner Meeting—March 3—RSVP by March 1

 

NPGS logo
Geologic Characterization of Yucca Flat, Nevada, Using the Seismic Hammer™

WHAT:  Monthly Dinner Meeting
WHEN:  Thursday, March 3, 2016
WHERE:  Ramada Reno Hotel
1000 East 6th Street, Reno, NV 89512
DETAILS:  Hosted Cocktail Reception 6:30, Skyline Bar, 14th Floor
Dinner Served at 7:00 PM
NPGS Members $20, Non-Members $23, Students $10
SPEAKER:   Robert E Abbott, Geophysicist, Sandia National Laboratories, Albuquerque, NM
TOPIC:  Geologic Characterization of Yucca Flat, Nevada, Using the Seismic Hammer™

ABSTRACT:  I present analysis of a multi-component, multi-channel, active-source seismic dataset acquired at the Nevada National Security Site (formerly the Nevada Test Site) using a prototype 13,000-kg weight-drop source. The purpose of the test was to determine the suitability of the source, called the Seismic Hammer™, for basin-scale characterization of Yucca Flat, Nevada. The source generates seismic energy by lifting the mass 1.5 meters before dropping it on a 1.8-m diameter plate. This results in over 190,000 Joules of potential energy being released. My results show that this results in ground motions similar to those produced by 20-kg of TNT equivalent explosives.

Two intersecting linear transects, 24-km and 14-km long, were acquired in 2015 with the goal of characterizing seismic propagation characteristics and geologic structure in advance of Phase II of the Source Physics Experiments (SPE). The goal of SPE is to use a series of underground chemical explosions at Yucca Flat to understand the mechanisms of shear wave generation from underground explosions. Shear-wave energy content is one major discriminant between earthquake and explosion sources and forms the basis of algorithms designed to monitor for worldwide nuclear tests.

My analysis shows that the Seismic Hammer™ is a source with unique properties and was well suited to data acquisition at Yucca Flat. Unlike vibrator sources, the Hammer produces significant energy below 2 Hz, allowing for usable data at source-receiver offsets as far as 11 km. Another benefit, in contrast to explosives, is the ability to hit multiple times at the same source point and stack the data, increasing the signal-to-noise-ratio. P-wave velocity structure was constrained to 2.5-km depth, well below the Paleozoic basement underlying the basin. Correlation of velocity structure to the known geology (Yucca Flat has thousands of boreholes due to underground nuclear testing) is excellent. S-Wave velocity structure was also recovered using the Refraction-Microtremor (ReMi) method. The quality of the shear-wave data was inversely proportional to the proximity to old nuclear tests.

Sandia National Laboratories is a multi-program laboratory managed and operated by Sandia Corporation, a wholly owned subsidiary of Lockheed Martin Corporation, for the U.S. Department of Energy’s National Nuclear Security Administration under contract DE-AC04-94AL85000.

BIOGRAPHY:  Robert Abbott is a Principal Member of the Technical Staff at Sandia National Laboratories in Albuquerque, New Mexico. He received a Bachelor of Science in Physics in 1995, and a Ph.D. in Geophysics in 2001 from the University of Nevada, Reno. His dissertation (directed by John Louie) focused, in part, on the basin structure of southern Dixie Valley, Nevada. At Sandia since 2001, Dr. Abbott has primarily worked on issues surrounding explosion source phenomenology, seismic nuclear monitoring, nuclear nonproliferation, and geophysical characterization. Much of his work has taken place at the Nevada National Security Site (NNSS, formerly the Nevada Test Site).

DGSE/GPHS Lectures—Feb 29 and Mar 4

A message from Dr. Scott McCoy, Department of Geological Sciences and Engineering (DGSE) about upcoming lectures:

1) Monday, February 29th at 5 PM in LME 425, Dr. Ramon Arrowsmith from ASU will give the Slemmons Lecture titled: High Resolution Topography and Active Faulting.

An update from Dr. Scott Mccoy, DGSE: Our speaker for today is delayed due to fog in San Francisco. His talk will now take place at 5 o’clock in LME 425. Note new location! Given the later time, we will start the standard social concurrently with the talk.

2)  Friday March 4GPHS (Graduate Program of Hydrologic Sciences) and DGSE are cosponsoring a colloquium by Dr. Mark Engle, a graduate of the GPHS program who now works for the USGS in Texas. He will talk about “Geochemistry and origin of produced waters from shale gas and tight oil reservoirs” in DMS 110 at 4 pm.

Geothermal Resource Potential Assessment, White Pine County

Geothermal resources can potentially contribute toward the renewable energy portfolio of White Pine County (WPC) in two ways: first through the direct conversion of heat energy into electricity, and the second by way of direct-use applications in which thermal energy is used as a source of heat for buildings, greenhouses, and related structures. Several known geothermal areas within WPC lie proximal to the Southwest Intertie power line currently under construction.

A potential source of electricity could come from conventional geothermal systems associated with young faults and regions of active crustal deformation. These systems have a total installed capacity in the Great Basin region of nearly 1,000 MWe. White Pine County hosts several geothermal systems of this type, but none are currently producing electricity. White Pine County has relatively low rates of crustal deformation relative to western Nevada or the Wasatch region of Utah (e.g., faulting accommodating crustal extension). However, based on a review of the geology in the region, we conclude that sustained and reasonable exploration efforts could result in the discovery and development of one or more electricity-grade geothermal systems, with potential generation capacity at each system in the range of 1–20 MWe.

In addition, a new and unproven type of potential geothermal resource termed “deep stratigraphic reservoirs” or “hot sedimentary aquifers” has recently been proposed in the western United States. White Pine County, and in particular, the northern Steptoe Valley, has some of the most promising potential for electricity generation from this type of reservoir in the United States. Preliminary calculations suggest that as much as 500 MWe of baseload electricity in the northern Steptoe Valley could be produced from this type of reservoir using wells reaching depths of 2 to 4 km. The economic feasibility remains unproven, but initial estimates are encouraging.

Based on observed surface temperatures and flow rates of springs, several geothermal systems in WPC also have the potential for direct use, including the heating of buildings and greenhouses. Such uses could reduce the consumption of electricity generated from fossil fuels and could lead to economic expansion by extending the growing season for certain agricultural products and reducing utility costs.

Funding for this work was provided by a grant from the Department of Energy.
