f Quantification of uncertainties in AVO analysis

AVO is today regarded as an important technique in the seismic industry because of its potential ability to find hydrocarbons directly from seismic data. The reflection coefficients as a function of angle (or offset) are determined by the Zoeppritz equations or approximations thereof. Examples of such approximations have been made by Aki and Richards (1980) and Shuey (1985) using a small contrast assumption.
