Abstract

Summary

Multiply scattered seismic waves, due to increased scattering, provide redundancy that can be used to detect and image weak time-lapse changes within a medium. These are weak changes that are not usually resolved with singly scattered waves. Previous efforts to use multiply scattered waves, use analytic model approximations of the scattered waves such as diffusion model to develop the sensitivity kernels needed for the time-lapse imaging. In a complex medium, the analytic model can become inaccurate in describing the features of the scattered intensity. In this paper, we demonstrate an alternative approach to computing the sensitivity kernel that can be used to image weak changes using multiply scattering waves. We numerically simulate the scattered intensity needed for the computation of the kernel using finite difference modeling. In most complex media, the numerical intensity will be a more accurate description of the scattered intensity than the diffusion model. Also we demonstrate the use of multiply scattered waves in resolving the weak changes in a 3D concrete block due to stress loadings to the surface of the block.
