Title: An application of Ray + Born inversion on real data

Abstract

The authors present a linearized 2D acoustic and elastic multiparameter inversion of real marine seismic reflection data from the Gulf of Mexico. They solve the forward problem by a combination of Ray Theory and Born approximation. It fully takes advantage of efficiency of ray tracing in terms of computing, cost and physical comprehension. Lateral variations of background velocities can be introduced in the 2D ray tracing algorithm and a 2.5D approximation is done in order to take into account 3D propagation. The multiparameter inversion method is based on minimization of a weighted cost function. This weighted cost function is estimated from parameters associated with Ray and Paraxial Ray Theory and is introduced in order to diagonalize approximately the Hessian. This form of the Hessian allows the study of spatial resolution and conditioning of inversion.
