Q Measurements - The effect of layering

A major role of seismic interpretation is the inference of physical properties of propagation media. The inversion from seismic to physical properties is far from unique. This job requires a range of seismic measurements of seismic parameters, among which are seismic velocity, absorption, impedance, and Poisson's ratio. Seismic absorption may be difficult to measure. For example, seismic attenuation, is more sensitive to clay content than seismic velocity (Klimentoes and McCann, 1990). There are many different mechanisms for seismic absorption.
