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: 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

Download or read book Applied Geophysics written by W. M. Telford and published by Cambridge University Press. This book was released on 1990-10-26 with total page 796 pages. 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: 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.
