Long story short: AVO is awesome.Īs you may know, I'm a big fan of forward modeling - predicting the seismic response of an earth model. Happily, this angular reflectivity encodes elastic rock property information. The AVO method is based on the fact that the reflectivity of a geological interface does not depend only on the acoustic rock properties (velocity and density) on both sides of the interface, but also on the angle of the incident ray. Amplitude vs offset (or, more properly, angle) analysis is a core component of quantitative interpretation.
