A proposal for regularized inversion for an ill-conditioned deconvolution operator

Abstract: From the inverse problem theory aspect, deconvolution can be understood as the linear inversion of an ill-posed and ill-conditioned problem. The ill-conditioned property of the deconvolution operator make the solution of inverse problem sensitive to errors in the data. Tikhonov regularization is the most commonly used method for stability and uniqueness of the solution. However, results from Tikhonov method do not provide sufficient quality when the noise in the data is strong. This work uses the conjugate gra… Show more

“…Wang et al [11] applied the conjugate gradient method to sweet spot prediction of shale gas and used wideangle seismic data to improve the accuracy of inversion result. Gonzalez et al [12] conducted regularization and nonregularization deconvolution algorithm, which effectively improved vertical resolution. As conjugate gradient method of local optimization has advantages of non-heuristic and heuristic inversion methods, petroleum reservoir prediction has reached goals in many regions, but for complicated structure-lithology petroleum reservoir, it is very difficult to obtain satisfying result of seismic prediction.…”
