ABSTRACT

More and more seismic surveys produce 3D seismic image in depth domain by using pre-stack depth migration methods, which can present direct subsurface structure in depth rather than in time domain. This leads to the increasing needs for applications of seismic inversion on the depth imaged seismic data for reservoir characterization. To address this issue, we developed a depth domain seismic inversion method with compressed sensing technique with output of reflectivity and band-limited impedance. The formulations of the seismic inversion in depth domain are similar as time domain methods but implementing all of the elements in depth domain, for example a depth domain seismic well tie. The developed method was first tested on a synthetic data, showing great improvement of the resolution on inverted reflectivity. We later applied the method on a depth migrated field data with well-log data validated, showing great fit between them and also improved resolution on the inversion results, which demonstrates the the feasibility and reliability of the proposed method on depth domain seismic data.
