Book Description
The objective of this project is to study the theory and measurement of dispersion during miscible flow in heterogeneous nonuniform anisotropic porous media. An understanding of the dispersion phenomenon is necessary to predict flow of miscible fluids in non-homgeneous porous media. A significant literature review of dispersion in non-homogeneous porous media was accomplished. The continuum and statistical theories of flow in porous media were studied. A series of experiments in models of unconsolidated porous media were run to study the effects of heterogeneity, nonuniformity, and anisotropy on dispersion. The non-homogeneities are defined in relation to permeability of the media and dispersion coefficients are correlated with respect to permeability. Tracer output curves from models were interpreted for dispersion. Dispersion changes significantly with permeability. When models of different permeability are connected, the dispersive effect is not reciprocal. Dispersion changes significantly with nonuniformity. Likewise there is a significant effect when models of different nonuniformity are interconnected (second-order heterogeneity). Anisotropy was included in two kinds of models (linear and radial) by packing alternate layers of beads causing flow through these layers at different angles. The usual dispersion model is not adequate for "block box" prediction of the tracer output curve for data on anisotropic shperes. The results have immediate practical applicates, especially in tracing of contaminents in surface and subsurface flow such as movement of pesticides, fertilizers, acid mine drainage, feed-lot waste, etc. through the soil.

Book Description
Authored by the internationally renowned José M. Carcione, Wave Fields in Real Media: Wave Propagation in Anisotropic, Anelastic, Porous and Electromagnetic Media examines the differences between an ideal and a real description of wave propagation, starting with the introduction of relevant stress-strain relations. The combination of this relation and the equations of momentum conservation lead to the equation of motion. The differential formulation is written in terms of memory variables, and Biot's theory is used to describe wave propagation in porous media. For each rheology, a plane-wave analysis is performed in order to understand the physics of wave propagation. This book contains a review of the main direct numerical methods for solving the equation of motion in the time and space domains. The emphasis is on geophysical applications for seismic exploration, but researchers in the fields of earthquake seismology, rock acoustics, and material science - including many branches of acoustics of fluids and solids - may also find this text useful. New to this edition: This new edition presents the fundamentals of wave propagation in Anisotropic, Anelastic, Porous Media while also incorporating the latest research from the past 7 years, including that of the author. The author presents all the equations and concepts necessary to understand the physics of wave propagation. These equations form the basis for modeling and inversion of seismic and electromagnetic data. Additionally, demonstrations are given, so the book can be used to teach post-graduate courses. Addition of new and revised content is approximately 30%. Examines the fundamentals of wave propagation in anisotropic, anelastic and porous media Presents all equations and concepts necessary to understand the physics of wave propagation, with examples Emphasizes geophysics, particularly, seismic exploration for hydrocarbon reservoirs, which is essential for exploration and production of oil
