This book was released on 1979 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In several recent investigations, experimental studies on the effect of normal stress on the hydraulic conductivity of a single fracture were made on three rock specimens ranging in cross-sectional area from 0.02 m2 to over 1.0 m2. At the maximum stress levels that could be attained (10 to 20 MPa), minimum values of the fracture hydraulic conductivity were not the same for each rock specimen. These minimum values increased with specimen size, indicating that the determination of fracture conductivity may be significantly influenced by a size effect. The implications of these results are important. Cores collected in the field are normally not larger than 0.15 m in diameter. However, the results of this work suggest that when this size core is used for laboratory investigations, the results may be nonconservative in that fracture permeabilities will be significantly lower than will be found in the field. 6 figures.

Download or read book Fractals in Petroleum Geology and Earth Processes written by C.C. Barton and published by Springer Science & Business Media. This book was released on 1995-01-31 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: A collection of significant papers dealing with fractal geometry and the petroleum industry. Contributed by some of the pioneers in the field, they represent a broad spectrum of applications from petroleum exploration to production, and serve as an introduction to the subject. The collection begins with a contribution by Benoit Mandelbrot, the "Father of Fractals," on the Paretian distribution. The substantial (5-page) foreword to the volume is also by Mandelbrot.

Download or read book Coupled Thermo Hydro Mechanical Processes of Fractured Media written by O. Stephanson and published by Elsevier. This book was released on 1997-02-10 with total page 597 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work brings together the results, information and data that emerged from an international cooperative project, DECOVALEX, 1992-1995. This project was concerned with the mathematical and experimental studies of coupled thermo(T) -hydro(H) -mechanical(M) processes in fractured media related to radioactive waste disposal. The book presents, for the first time, the systematic formulation of mathematical models of the coupled T-H-M processes of fractured media, their validation against theoretical bench-mark tests, and experimental studies at both laboratory and field scales. It also presents, for the first time, a comprehensive analysis of continuum, and discrete approaches to the study of the problems of (as well as a complete description of), the computer codes applied to the studies. The first two chapters provide a conceptual introduction to the coupled T-H-M processes in fractured media and the DECOVALEX project. The next seven chapters give a state-of-the-art survey of the constitutive models of rock fractures and formulation of coupled T-H-M phenomena with continuum and discontinuum approaches, and associated numerical methods. A study on the three generic Bench-Mark Test problems and six Test Case problems of laboratory and field experiments are reported in chapters 10 to 18. Chapter 19 contains lessons learned during the project. The research contained in this book will be valuable for designers, practising engineers and national waste management officials who are concerned with planning, design and performance, and safety assessments of radioactive waste repositories. Researchers and postgraduate students working in this field will also find the book of particular relevance.

Download or read book Field Hydrogeology written by John E. Moore and published by CRC Press. This book was released on 2011-08-04 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, the focus in hydrogeologic investigations has expanded to include aquifer sustainability as part of resource evaluations. While there are other books on the subject, Field Hydrogeology: A Guide for Site Investigations and Report Preparation provides the first integrated presentation of the American Society of Testing Materials (ASTM) standards, US Geological Survey (USGS), and US Environmental Protection Agency (EPA) field techniques. It also includes access to a website containing software for designing aquifer tests and aquifer-recharge experiments. Written by an author with more than 50 years of experience in hydrology and geology, this reference treats the subject from a field standpoint. Useful as a field guide or textbook, it contains standard methods for planning and undertaking hydrogeologic investigations. It incorporates case studies, contains a glossary of field-hydrogeology technical terms, and provides a detailed list of ASTM standards and key hydrologic Web sites. The guide is based on ASTM standards as well as EPA and US Department of Interior field technical manuals. The text covers hydrogeologic fundamentals, conceptual models, planning an investigation, surface investigations, subsurface investigations, field inventory, stream flow measurements, water quality measurements, and report preparation. This revised and updated Second Edition also includes new material on the history of hydrogeology, field safety, aquifers, groundwater quality, hydrogeologic maps, and federal regulations. It gives students and seasoned professionals a vast array of clearly written descriptive materials and an extensive source of references available at their fingertips. What’s New in This Second Edition: New chapter on the history of hydrogeology New chapter on groundwater development and management, including US federal regulations and transboundary aquifers New material on field safety, groundwater quality and testing, and construction of hydrogeologic cross section and maps New international case studies New THEIS computer model to design aquifer tests Updated information on latest principles and techniques
