Method for minimizing residual shot noise from seismic data

摘要

A method of minimizing residual shot noise from seismic data, comprises: (a) synchronizing the seismic data with reference to the firing time of a first shot at time equal to zero; (b) synchronizing the seismic data with reference to the firing time of a second shot at time equal to zero, wherein the first shot is activated following the activation of the second shot; (c) applying a lateral coherence filter to the seismic data created at step (b); (d) synchronizing the seismic data created at step (c) with reference to the firing time of the first shot at time equal to zero; and (e) subtracting the seismic data created at step (d) from the seismic data created at step (a).
