Comparison between different elastic imaging techniques on 2D OBS data

Abstract

We present a comparative study of different elastic imaging techniques, performed on a 2D OBS acquisition. We experiment three imaging methods to illuminate a given target zone. The first one is a linearized elastic inversion method using a conjugate gradient; the Green’s functions are computed by finite differences. The other methods are true-amplitude elastic Kirchhoff migrations. The second method is performed in the depth domain, with asymptotic Green’s functions computed by a dynamic ray tracing algorithm. The third method is performed in the time domain, where the Green’s functions are explicitly obtained from a T -X traveltime approximation. Comparison is made with respect to the quality of the results, such as image resolution and top reservoir delineation.
