The advent of accessible student computing packages has meant that geophysics students can now easily manipulate datasets and gain first-hand modeling experience - essential in developing an intuitive understanding of the physics of the Earth.

Yet to gain a more in-depth understanding of physical theory, and to develop new models and solutions, it is necessary to be able to derive the relevant equations from first principles. This compact, handy book fills a gap left by most modern geophysics textbooks, which generally do not have space to derive all of the important formulae, showing the intermediate steps.

This guide presents full derivations for the classical equations of gravitation, gravity, tides, earth rotation, heat, geomagnetism and foundational seismology, illustrated with simple schematic diagrams. It supports students through the successive steps and explains the logical sequence of a derivation - facilitating self-study and helping students to tackle homework exercises and prepare for exams. This core undergraduate textbook presents a comprehensive overview of each major branch of theoretical and applied geophysics.

A practical handbook for the petroleum geophysicist. Fundamental concepts are explained using heuristic descriptions of seismic modeling, deconvolution, depth migration, and tomography. Pitfalls in processing and contouring are described briefly. Applications include petroleum exploration of carbonate reefs, salt intrusions, and overthrust faults.

The book includes past, present, and possible future developments in time-lapse seismology, borehole geophysics, multicomponent seismology, and integrated reservoir characterization. Geophysical techniques apply the principles of physics for study of physical responses of rocks under passive or active perturbation.

Geophysical data acquisition, processing and interpretation are driven by established scientific principles. Data from geophysical tools provide coverage with spatially continuous high density measurements. Well data like cores and well logs provide vertically high resolution measurements at the well location, however, the distribution of wells is sparse and discontinuous. The detailed spatial coverage from geophysical data are calibrated with analysis of well logs, pressure tests, cores, geologic depositional knowledge and other information from appraisal wells.

The methods use high precision sensors that measure the properties on the earth's surface, in oceans, in wells and from the air, also from satellites.

They measure changes of physical properties and calibrate the measured geophysical attributes with rock properties. The data play important role in developing a gross reservoir model.

The reservoir architecture or structure and the reservoir rock and fluid properties are derived from the analysis and data integration.

Other reservoir properties that can affect geophysical measurements are density, oil viscosity, stresses, and fractures. The interpretation has inherent ambiguity or multiple interpretations. Geophysics contributes to reservoir characterization, reservoir monitoring and its management by adding maximum value in improving production plan and by minimizing risk e.

Multiple geologic parameters are assessed with the same geophysical data. This is the revised and updated version of an established textbook.

It describes the physical methods involved in exploration for hydrocarbons and minerals. These tools include gravity, magnetic, seismic, electrical, electromagnetic, and radioactivity studies. Covers the fundamentals of all currently used methods seismic, electrical, electromagnetic, gravity, magnetic, borehole logging and remote sensing and pays special attention to the seismic refraction and electrical resistivity techniques which are the ones most commonly used in engineering and groundwater geophysics.

The main changes in this new edition of Applied Geophysics for Engineers and Geologists, apart from a general updating, and conversion to SI units, is a more extensive treatment of electromagnetic and induced polarisation methods, and of geophysical borehole logging.

The seismic reflection method is also treated more fully in view of its great importance in petroleum prospecting. Problems, with answers are also included. Taken together, the changes are so great that this is virtually a new book, as is suggested by the change in title.

This newly-translated book takes the reader from the basic principles and conservation laws of hydrodynamics to the description of general atmospheric circulation. Among the topics covered are the Kelvin, Ertel and Rossby-Obukhov invariants, quasi-geostrophic equation, thermal wind, singular Helmholtz vortices, derivation of the Navier-Stokes equation, Kolmogorov's flow, hydrodynamic stability, and geophysical boundary layers. Generalizing V. Arnold's approach to hydrodynamics, the author ingeniously brings in an analogy of Coriolis forces acting on fluid with motion of the Euler heavy top and shows how this is used in the analysis of general atmospheric circulation.

This book is based on popular graduate and undergraduate courses given by F. Dolzhansky at the Moscow Institute of Physics and Technology, and is the result of the author's highly acclaimed work in Moscow's Laboratory of Geophysical Hydrodynamics. Each chapter is full of examples and figures, exercises and hints, motivating and illustrating both theoretical and experimental results. The exposition is comprehensive yet user-friendly in engaging and exploring the broad range of topics for students and researchers in mathematics, physics, meteorology and engineering.

Description This second edition of Fundamentals of Geophysics has been completely revised and updated, and is the ideal geophysics textbook for undergraduate students of geoscience with an introductory level of knowledge in physics and mathematics.

It fundmental a comprehensive treatment of the fundamental principles of each major branch of geophysics, and presents geophysics within the wider context of plate tectonics, geodynamics and planetary science.

Basic principles are explained with the aid of numerous figures and step-by-step mathematical treatments, and important geophysical results are illustrated with examples from the scientific literature.

Text-boxes are used for auxiliary explanations and to handle topics of interest for more advanced students. Solutions to the exercises and electronic copies of the figures are available at www. Visit our Beautiful Books page and find lovely books for kids, photography lovers and more. Table of contents Preface; 1. The Earth as a planet; 2. Gravity and the figure of the Earth; 3.

Seismology and the internal structure of the Earth; 4. Review quote Reviews from the first edition: I highly recommend this volume as a must-have, middle-level, highly instructive textbook that makes for enjoyable reading at an easily affordable price. The scientific treatment is meticulous. Each topic is described precisely and clearly William Lowrie simplifies the maths to about second-year degree level I have already found it helpful in teaching second-year geology students and have no doubt that it will be a useful reference book for undergraduates.

It is clearly written, beautifully illustrated, and has the appropriate balance between mathematical and descriptive treatment. I particularly like the brief historical accounts that accompany each chapter. The new second edition includes text boxes that deal concisely with specific background topics e. Fourier transformsas well as useful exercises for students at the end of each chapter. I have recommended the first edition His research interests include rock magnetism, magnetostratigraphy, and tectonic applications of paleomagnetic methods.
