Acoustics of porous media

Book ·
OSTI ID:5295884
During the past two decades research has been conducted on quantifying the relationship between seismic properties of oil-bearing rocks and their production properties (porosity, clay content, fracture density, and permeability). This book describes concepts of how seismic methods can be applied to assist in determining petroleum bearing reservoir rock parameters. Predicting the migration of the reservoir gas cap in discontinuous shales, producing from over-pressure zones, and tracking steam and temperature migration in thermal recovery operations are a few parameters that future seismic methods will resolve. This is a comprehensive reference on most of what is known about the propagation of acoustic waves in porous media. Physical aspects of wave propagation, attenuation, and measurement of acoustics in porous media are emphasized. Chapter 1 introduces the qualitative and quantitative description and analysis of porous media. Chapters 2 and 3 discuss theoretical aspects of acoustic wave propagation in saturated porous media and viscoelastic media. Chapter 4 analyzes various techniques for measuring velocities and attenuations in materials. Chapter 5 describes several laboratory and field measurements of velocities and attenuations and analyzes them quantitatively in physical terms. Chapter 6 discusses concepts in saturated and viscoelastic porous media and includes examples of sonic log data. Chapter 7 analyzes future geophysical applications of measuring the acoustics of porous media.
