Abstract

Summary

The seabed seismic industry is heading towards an acquisition paradigm shift where dense ocean-bottom systems are becoming less and less attractive in favour of sparse node geometries. It is therefore important to adapt technologies that previously relied on the availability of regular (and possibly dense) receiver carpets to this new sparse standard. In this work, we present a reciprocal version of the Rayleigh-Marchenko method that, whilst preserving all of the features of the original method, can handle irregular and sparse receiver geometries, provided availability of multi-component receivers and either dual-sensor sources or a pre-processing step of model-based source deghosting. A synthetic example is presented to validate the effectiveness of the proposed method and evaluate its robustness to sparse receiver geometries.
