An AVAF inversion method for detecting hydrocarbons

Rock physics studies have shown that velocity dispersion is often associated with hydrocarbon deposit, which results in P-wave reflection coefficients varying with frequency. This effect is often neglected in conventional amplitude versus angle or offset inversion, and thus error is introduced. Here we propose a method for inverting for dispersive velocity from the frequencydependent P-wave reflection coefficients; the method is called amplitude variation with angle and frequency AVAF inversion.
