Available in PDF, EPUB and Kindle. Book excerpt: Overvoltage Research and Geophysical Applications deals with the subject of overvoltage (or induced electrical polarization) as it relates to geophysical exploration. This book presents the results of theoretical and experimental research conducted between 1946 and 1958 to investigate overvoltage and sponsored by Newmont Mining Corporation. This book is comprised of 10 chapters and begins with a brief overview of the history of Newmont's interest in overvoltage. The next chapter describes a theory for induced polarization effects (for step-function excitation), with particular reference to a mathematical formulation that represents the volume distribution of dipolar sources. The reader is then introduced to a brief theoretical derivation for the effective conductivity and dielectric constant of a homogeneous medium loaded with a uniform distribution of spherical conducting particles. The following chapters explore the complex conductivity of rocks as a function of frequency; laboratory studies of induced polarization in mineralized and non-mineralized rock specimens; induced polarization decay curves on rock specimens; and phenomena resulting from electric polarization of rocks at low frequencies. Some electrical transient measurements on igneous, sedimentary, and metamorphic rocks are presented. The final chapter considers various explanations of the normal effect and describes induced-polarization experiments. This monograph will be of interest to geophysicists.

Available in PDF, EPUB and Kindle. Book excerpt: This is the completely revised and updated version of the popular and highly regarded textbook, Applied Geophysics. It describes the physical methods involved in exploration for hydrocarbons and minerals, which include gravity, magnetic, seismic, electrical, electromagnetic, radioactivity, and well-logging methods. All aspects of these methods are described, including basic theory, field equipment, techniques of data acquisition, data processing and interpretation, with the objective of locating commercial deposits of minerals, oil, and gas and determining their extent. In the fourteen years or so since the first edition of Applied Geophysics, many changes have taken place in this field, mainly as the result of new techniques, better instrumentation, and increased use of computers in the field and in the interpretation of data. The authors describe these changes in considerable detail, including improved methods of solving the inverse problem, specialized seismic methods, magnetotellurics as a practical exploration method, time-domain electromagnetic methods, increased use of gamma-ray spectrometers, and improved well-logging methods and interpretation.

Available in PDF, EPUB and Kindle. Book excerpt: The authors review spectral induced polarization theory and describe some of the SIP method's applications through a discussion of their research in the People's Republic of China. In the first of four chapters, they discuss the electrochemical basis of SIP, offering proof of the validity of using the Cole-Cole model for describing complex resistivity spectra. In the next chapter, which addresses the SIP forward problem, they describe the scale-modeling laws for SIP, various forward algorithms, the behavior and variation laws of SIP anomalies, and effective SIP parameters. The third chapter discusses SIP inversion methods, including several methods of calculating the intrinsic spectral parameters of a polarizable body. In the final chapter, the authors describe their field tests applying the SIP method to prospecting for orebodies and oil and gas reservoirs. The material is introduced in part through a reprinting of a 1959 paper by Volume Editor James R. Wait titled 'The Variable Frequency Method."

This book was released on 2014-10-08 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrokinetics is a term applied to a group of physicochemical phenomena involving the transport of charges, action of charged particles, effects of applied electric potential and fluid transport in various porous media to allow for a desired migration or flow to be achieved. These phenomena include electrokinetics, electroosmosis, ion migration, electrophoresis, streaming potential and electroviscosity. These phenomena are closely related and all contribute to the transport and migration of different ionic species and chemicals in porous media. The physicochemical and electrochemical properties of a porous medium and the pore fluid, and the magnitudes of the applied electrical potential all impact the direction and velocity of the fluid flow. Also, an electrical potential is generated upon the forced passage of fluid carrying charged particles through a porous medium. The use of electrokinetics in the field of petroleum and environmental engineering was groundbreaking when George Chilingar pioneered its use decades ago, but it has only been in recent years that its full potential has been studied. This is the first volume of its kind ever written, offering the petroleum or environmental engineer a practical "how to" book on using electrokinetics for more efficient and better oil recovery and recovery from difficult reservoirs. This groundbreaking volume is a must-have for any petroleum engineer working in the field, and for students and faculty in petroleum engineering departments worldwide.

Available in PDF, EPUB and Kindle. Book excerpt: Developments in Economic Geology, 5: Principles of Induced Polarization for Geophysical Exploration focuses on the principles, methodologies, and approaches involved in induced polarization (IP), including anisotropism, electromagnetic coupling, and electrical circuits. The book first takes a look at resistivity principles, theory of IP, and laboratory work in IP. Concerns cover electrical measurements of rocks, anisotropism, early part of decay curve and the comparison with frequency effects, electrical models of induced polarization, electrical polarization, resistivities of earth materials, and resistivity exploration methods. The manuscript then elaborates on IP field equipment, telluric noise and electromagnetic coupling, IP field surveying, and drill-hole and underground surveying and the negative IP effect. Discussions focus on differences between surface and subsurface methods, current-sending system in the field, telluric (earth) currents, electromagnetic coupling, design considerations, coupling of electrical circuits, design considerations, and signal-generating system. The manuscript ponders on the complex-resistivity method and interpretation of induced-polarization data, including grade estimation of mineralization using the IP method, complex-resistivity survey, signal detection capabilities of the complex-resistivity method, and disadvantages of the complex-resistivity method. The text is a valuable source of information for researchers wanting to study induced polarization.

Available in PDF, EPUB and Kindle. Book excerpt: For some years I have felt there was a need for a single, comprehen sive, reference book on exploration geology. Numerous textbooks are available on subjects such as geophysical prospecting, exploration geochemistry, mining geology, photogeology and general economic geology, but, for the geologist working in mineral exploration, who does not require a specialist's knowledge, a general book on explora tion techniques is needed. Many undergraduate university courses tend to neglect economic geology and few deal with the more prac tical aspects in any detail. Graduate geologists embarking on a career in economic geology or mineral exploration are therefore often poorly equipped and have to learn a considerable amount 'on the job'. By providing a book that includes material which can be found in some of the standard texts together with a number of practical aspects not to be found elsewhere, I hope that both recent graduates and more experienced exploration geologists will find it a useful reference work and manual. In addition, students of economic geology and personnel working in related fields in the mining and mineral extraction in dustries will find it informative. J. H. REEDMAN v Acknowledgements The author would like to thank Dr K. Fletcher, geochemist with the Department of Geology, University of British Columbia, and Kari Savario, geophysicist with Finnish Technical Aid to Zambia, for reading the original drafts and offering constructive criticism and advice on the chapters on geochemical and geophysical prospecting respectively.

This book was released on 2000-05-10 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Just below our feet is an environment that supports our infrastructure, yields water, provides for agriculture, and receives our waste. Our capacity to describe, or characterize, this environment is crucial to the solution of many resource, environmental, and engineering problems. And just as medical imaging technologies have reduced the need for exploratory surgeries, a variety of technologies hold the promise for rapid, relatively inexpensive noninvasive characterization of the Earth's subsurface. Seeing into the Earth examines why noninvasive characterization is important and how improved methods can be developed and disseminated. Looking at the issues from both the commercial and public perspectives, the volume makes recommendations for linking characterization and cost savings, closing the gap between the state of science and the state of the practice, and helping practitioners make the best use of the best methods. The book provides background on: The role of noninvasive subsurface characterization in contaminant cleanup, resource management, civil engineering, and other areas. The physical, chemical, biological, and geological properties that are characterized. Methods of characterization and prospects for technological improvement. Certain to be important for earth scientists and engineers alike, this book is also accessible to interested lay readers.

Available in PDF, EPUB and Kindle. Book excerpt: ACOUSTIC AND VIBRATIONAL ENHANCED OIL RECOVERY Oil and gas is still a major energy source all over the world, and techniques like these, which are more environmentally friendly and inexpensive than many previous development and production technologies, are important for making fossil fuels more sustainable and less hazardous to the environment. Based on research they did in the 1970s in Russia and the United States, the authors discovered that oil rate production increased noticeably several days after the occurrence of an earthquake when the epicenter of the earthquake was located in the vicinity of the oil producing field. The increase in oil flow remained higher for a considerable period of time, and it led to a decade-long study both in the Russia and the US, which gradually focused on the use of acoustic/vibrational energy for enhanced oil recovery after reservoirs waterflooded. In the 1980s, they noticed in soil remediation studies that sonic energy applied to soil increases the rate of hydrocarbon removal and decreases the percentage of residual hydrocarbons. In the past several decades, the use of various seismic vibration techniques have been used in various countries and have resulted in incremental oil production. This outstanding new volume validates results of vibro-stimulation tests for enhanced oil recovery, using powerful surface-based vibro-seismic sources. It proves that the rate of displacement of oil by water increases and the percentage of nonrecoverable residual oil decreases if vibro-energy is applied to the porous medium containing oil. Audience: Petroleum Engineers, Chemical Engineers, Earthquake and Energy engineers, Environmental Engineers, Geotechnical Engineers, Mining and Geological Engineers, Sustainability Engineers, Physicists, Chemists, Geologists, and other professionals working in this field
