Book Description
This book brings together for the first time the results of research on the thermal properties and temperature-related behavior of rocks with their contained fluids, under subsurface environmental conditions. These data are of increasing importance with increased application of underground processes involving high temperature and, in some cases, low temperature environments. Some of the important processes are described in which thermal data are needed. Chapters deal with thermal properties of rocks, including heat capacities, thermal conductivities and thermal diffusivities under conditions simulating subsurface environments. Discussion about the difficulty in measuring thermal properties of rock/fluid systems is included along with newly-developed models for predicting thermal properties from more-easily measured properties. The effects of thermal reactions in rocks, differential thermal expansion, and thermal alterations are discussed in separate chapters. The effects of temperature on rock properties, as distinct from the irreversible effects of heating, are reviewed. Lastly the book deals with wellbore applications of thermal and high-temperature behavior of rocks and methods of deducing thermal properties from geophysical logs run in boreholes. Appendices include thermal units conversion factors and thermal properties of some typical reservoir rocks and fluids.

Book Description
This study is part of a program conducted by the Air Force Cambridge Research Laboratories on methods of detection and utilization of lunar water resources. The two principal objectives of this study were: 1. To aid in the assessment of lunar water extraction processes by obtaining data on the physical, thermal and mechanical properties of hydrated minerals and rock systems, and 2. To analyze the heat and mass transfer associated with several possible lunar water extraction processes, using data obtained from literature and from experimental studies. Particular emphasis was to be placed on heat transfer and control in fractured and unfractured rock systems containing hydrated minerals. Literature data on the density, thermal conductivity, specific heat, permeability, porosity, thermal diffusivity, and moisture content of rock systems are assembled and tabulated. Experimental data for six typical rocks were obtained and compared to literature data. The apparatus and methods used in the experimental program are described. The results of calculations of the heat and mass transfer associated with extraction of water from subsurface deposits and mined deposits are presented. (Author).

Book Description
Physical Properties of Rocks: A Workbook is a symbiosis of a brief description of physical fundamentals of rock properties (based on typical experimental results and relevant theories and models) with a guide for practical use of different theoretical concepts. For this purpose a companion web site contains a selection of model based equations in excel worksheets for practical application and training by the user to work with his own data (or to ''play" in order to demonstrate the effects of various input information and to demonstrate the effects of various input information in petrophysical work. In two special chapters the problem of relationships between petrophysical parameters based on various model concepts is presented as a foundation for combined interpretation. This part also contains the author's 'structured model'. The workbook is a result of the more than 40 years experience of the author in teaching at universities and industrial courses. - Presents all practical relevant properties of rock in one volume - Experimental and theoretical fundamentals in a systematic framework - Special focus on relationships between properties

Book Description
This volume provides an introduction to the texture analysis of deformed materials and explores methods of determining and interpreting the preferred orientation of crystals in deformed polycrystalline aggregates.**The book reviews: 1) the techniques, procedures, and theoretical basis for the accumulation and analysis of orientation data; 2)the processes by which polycrystals deform and the microstructural mechanisms responsible for the development of the preferred orientation; 3) the textures in specific systems and application of principles to the solution of specific problems.**With a combination of metallurgic and geologic applications, Preferred Orientation in Deformed Metals and Rocks: An Introduction to Modern Texture Analysis will be an important source book for students and researchers in materials science, solid state physics, structural geology, and geophysics.**FROM THE PREFACE: Determination and interpretation of the preferred orientation of crystals in deformed polycrystalline aggregates (in this volume also referred to as texture) has been of longstanding concern to both materials scientists and geologists. A similar theoretical background--such as the dislocation theory of crystal plasticity--has been the basis of understanding flow in metals and rocks; and similar determinative techniques--including microscopy and x-ray diffraction--have been used to study textures and microstructures. Whereas many of the fundamental principles have been established early this century by scientists such as Jeffery, Sachs, Sander, Schmid, Schmidt, and Taylor, only in recent years has knowledge reached a level that provides a quantitative framework which has replaced a largely phenomenological approach. This is expressed in the sudden new emphasis on textural studies, as documented by the large number of recent publications.**This volume contains material to serve as an introduction for those who wish to enter this field as well as reviews for those who are already engaged in advanced research....**The book is divided into three parts. The first (Chapters 2*b17) deals with techniques, procedures, and theoretical bases for the accumulation and analysis of orientation data. The second (Chapters 8*b112) introduces processes by which polycrystals deform and the microstructural mechanisms responsible for the development of the preferred orientation. All those chapters emphasize basic principles and apply to metals as well as to minerals. The third part (Chapters 13*b126) illustrates textures in specific systems and the application of the principles set out in the earlier chapters to the solution of specific problems. Readers of these chapters will quickly become aware that metals have been more exhaustively studied than minerals; but they will also realize that, because of their structural symmetry, metals are in general much simpler than rocks and that the intepretation of metal textures is less involved. An extensive list of relevant references provides access to much of the original literature on textures....

Book Description
The constantly growing demand for energy, as well as the realization during the past decade that fossil energy reserves to satisfy ever increasing energy consumption are limited, have helped, as part of the search for alternative energy sources, to bring the subject of geothermics to its present level of significance. Practical geothermics is concerned with prospecting for and develop ment of geothermal heat. General geothermics deals with the thermal state of our Earth as a whole. Both divisions of this field, however, contribute practical insights, and improved methods of temperature esti mation have helped to give us a better picture of detailed thermal condi tions. It is difficult for readers interested in this field to obtain an overview from the numerous, specialized papers that have been written on geother mics. This book is meant to provide a thorough introduction to the subject, although the coverage is not exhaustive is detail. Geothermics is taught at universities and technical institutes, as part of the curriculum in geology. This introduction to geothermics is directed especially to students of geophysics and is meant to be used as a supple ment to their lectures. of this work must be given to my Special thanks for the completion teacher, Prof. Dr. O. ROSENBACH. His lectures in geophysics inspired my interest in geothermics, which is still my main research area.
