Heat flow and microearthquake studies, Coso Geothermal Area, China Lake, California. Final report (open access)

Heat flow and microearthquake studies, Coso Geothermal Area, China Lake, California. Final report

The present research effort at the Coso Geothermal Area located on the China Lake Naval Weapons Center, China Lake, California, was concerned with: (1) heat flow studies and (2) microearthquake studies associated with the geothermal phenomena in the Coso Hot Springs area. The sites for ten heat flow boreholes were located primarily using the available seismic ground noise and electrical resistivity data. Difficulty was encountered in the drilling of all of the holes due to altered, porous, faulted, and sometime highly fractures zones. Thermal conductivity measurements were completed using both the needle probe technique and the divided bar apparatus with a cell arrangement. Heat flow values were obtaned by combining equilibrium temperature measurements with the appropriate thermal conductivity values. Heat, in the upper few hundred meters of the subsurface associated with the Coso Geothermal Area, is being transferred by a conductive heat transfer mechanism with a value of approximately 15 ..mu..cal/cm/sup 2/-sec. This is typical of geothermal systems throughout the world and is approximately ten times the normal terrestrial heat flow of 1.5 HFU. The background heat flow for the Coso region is about 3.5 HFU.

Impediments to geothermal development in Lake County, California (open access)

Impediments to geothermal development in Lake County, California

The areas of environmental and socio-political concern are addressed as viewed by the actors in the geothermal process in Lake County, where the actors are the governmental jurisdictions involved in the permitting process, and the various groups concerned about the social, economic, and environmental conditions in Lake County. Those interviewed included all local and state governmental entities involved in the geothermal permitting process, representatives of industry and utilities, the Lake County Energy Council, and with Lake County citizens involved in the geothermal debate. The topics discussed relate directly to the impediments seen to geothermal development by those involved in the process. Environmental concerns center around land use, air quality, and flora and fauna impact, with land use being of major concern. The major socio-political problem is the overlapping or conflicting governmental jurisdictions, although the Environmental Impact Reporting Process, the prospect of industrialization, and social attitudes are also of concern.

Index of harm: a measure for comparing occupational risk across industries (open access)

Index of harm: a measure for comparing occupational risk across industries

This areport explores the implications of an index-of-harm methodology that compares occupational risks among workers exposed to radiological and nonradiological harms. It extends the work of the International Commission on Radiological Protection (ICRP) by considering American rather than European and Japanese industry groups, by treating the relative importance of various occupational harms as a parameter rather than an arbitrary constant, and by identifying several ways in which both the methodology and the data base could be improved. Unfortunately, the data base is too fragmented, and radiological risk estimates are too imprecise for quantitative comparisons across industries. Inclusion of subjective risk preferences is one way to make policy-relevant judgments based on a limited data base. Our study agrees with known accidental fatality rates by showing the riskiest industries to be mining; agriculture, forestry, and fisheries; construction; transportation; and manufacturing - roughly in that order. Using a factor of five times the ICRP dose/risk parameter suggests that the index of harm for radiological workers exposed to 0.35 Rem/yr is still below that of the five riskiest industries. However, the rankings re altered considerably at the regulatory dose level of 5.0 Rem/yr. At that level, the nuclear industry would be significantly more risky, …

Study of geothermal prospects in the western United States (open access)

Study of geothermal prospects in the western United States

The commercial development potential of 13 underdeveloped geothermal prospects in the western United States has been examined and the prospects have been ranked in order of relative potential for development on the basis of investment considerations. The following were considered in the ranking: geotechnical and engineering data, energy market accessibility, administrative constraints, and environmental and socio-economic factors. The primary ranking criterion is the unit cost of energy production expected from each prospect. This criterion is obtained principally from expected reservoir temperatures and depths. Secondary criteria are administrative constraints, environmental factors and the quality of the geotechnical data. The Roosevelt, Utah, prospect ranks first in development potential followed in order by Beowawe, Nevada; Coso Hot Springs, California; Long Valley, California; and Brady's Hot Springs, Nevada.

Drilling for energy resources (open access)

Drilling for energy resources

Drilling is integral to the exploration, development, and production of most energy resources. Oil and natural gas, which are dependent on drilling technology, together account for about 77% of the energy sources consumed in the US. Thus, the limitations of current drilling technology also restrict the rate at which new energy supplies can be found, extracted, and brought to the marketplace. The purpose of the study reported was to examine current drilling technology, suggest areas where additional research and development (R and D) might significantly increase drilling rates and capabilities, and suggest a strategy for improving drilling technology. An overview is provided of the US drilling industry. The drilling equipment and techniques now used for finding and recovering oil, natural gas, coal, shale oil, nuclear fuels, and geothermal energy are described. Although by no means exhaustive, these descriptions provide the background necessary to adequately understand the problems inherent in attempts to increase instantaneous and overall drilling rates.

Continental drilling (open access)

Continental drilling

The Workshop on Continental Drilling was convened to prepare a report for submission to the US Geodynamics Committee with respect to the contribution that could be made by land drilling to resolve major problems of geodynamics and consider the mechanisms by which the responsibility for scientific planning, establishment of priorities, administration, and budgeting for a land-drilling program within the framework of the aims of the Geodynamics Project would best be established. A new and extensive program to study the continental crust is outlined in this report. The Workshop focused on the following topics: processes in the continental crust (mechanism of faulting and earthquakes, hydrothermal systems and active magma chambers); state and structure of the continental crust (heat flow and thermal structure of the crust; state of ambient stress in the North American plate; extent, regional structure, and evolution of crystalline continental crust); short hole investigations; present state and needs of drilling technology; drill hole experimentation and instrumentation; suggestions for organization and operation of drilling project; and suggested level of effort and funding. Four recommendations are set down. 8 figures, 5 tables. (RWR)

Statistical methods for environmental pollution monitoring (open access)

Statistical methods for environmental pollution monitoring

The application of statistics to environmental pollution monitoring studies requires a knowledge of statistical analysis methods particularly well suited to pollution data. This book fills that need by providing sampling plans, statistical tests, parameter estimation procedure techniques, and references to pertinent publications. Most of the statistical techniques are relatively simple, and examples, exercises, and case studies are provided to illustrate procedures. The book is logically divided into three parts. Chapters 1, 2, and 3 are introductory chapters. Chapters 4 through 10 discuss field sampling designs and Chapters 11 through 18 deal with a broad range of statistical analysis procedures. Some statistical techniques given here are not commonly seen in statistics book. For example, see methods for handling correlated data (Sections 4.5 and 11.12), for detecting hot spots (Chapter 10), and for estimating a confidence interval for the mean of a lognormal distribution (Section 13.2). Also, Appendix B lists a computer code that estimates and tests for trends over time at one or more monitoring stations using nonparametric methods (Chapters 16 and 17). Unfortunately, some important topics could not be included because of their complexity and the need to limit the length of the book. For example, only brief mention could …
