Abstract

Summary

In this paper we propose a two-phase automatic converted-wave statics correction method. Seed statics are estimated by maximizing the low-frequency components of the original broadband data stacking power using a genetic optimization algorithm. The resulting statics solution is more robust in the presence of cycle skipping. With seed statics as the initial values, the coordinate descent method is then used to maximize the stacking power of the original broadband data, as well as the spatial coherency of the common converted point stack. We demonstrate our automatic method on an OBC PS dataset with good success.
