A HIGH-ORDER PERTURBATIVE ANALYSIS OF SEISMIC ATTRIBUTES

A high-order perturbative analysis of seismic attributes such as trave l times, reflection coefficients and waveforms is presented. A number of simple 1-D numerical examples have been performed for the constant gradient and plane-layer velocity models. They confirm that the high-o rder perturbations remove the sensitivity of the linearized methods to the choice of the reference model and to the source-receiver position s. Restrictions on velocity gradient and velocity contrast at the inte rface implicit in the Born approximation are eliminated as well.
