A method for converted wave receiver statics correction in the CRG domain

Summary A method for receiver statics correction of converted waves (PS-waves) is proposed here. It is based on the observation that the static time delay on PS-wave events between two adjacent receivers, after the source statics correction has been applied, should correspond mostly to the differential receiver statics. The statics surface consistent model provides the theoretical framework. Adjacent Common Receiver Gathers (CRG) are crosscorrelated to obtain their time delay, namely their differential receiver statics. Stacking of PS-waves it is not required, therefore the method does not depend on Vc (stacking velocity for converted wave), neither does it assume a simplified stacking model such as asymptotic binning. Tests on synthetic data illustrate the resulting statics.
