Numerical solution of the problem of detecting diffractors in a complex acoustic media

One of the most effective methods for detecting weak scattering objects (diffractors) associated with cracked-cavernous hydrocarbon reservoirs is the CSP (Common Scattering Point) method [1]. This method is the most effective for weakly inhomogeneous media. The CSP method can be supplemented by a preliminary continuation of the wave field to a certain depth for strongly inhomogeneous medium. In this paper we use Reverse Time Datuming (RTD) procedure for this purpose [2, 3, 4]. The new CSP-RTD method is based on both CSP and RTD methods for determining deep-seated diffractors in complex acoustic medium. The results of numerical studies of CSP-RTD method for a complex acoustic model is presented. The comparison of CSP-RTD method and RTM method is also presented.
