Abstract

In this paper I apply two processing methods to reverse VSP data: iterative conjugate gradient migration and coherency stacking. Iterative conjugate gradient migration helps to eliminate the migration artifacts and produce a reflectivity distribution which is consistent with the observed seismogram. The second method, coherent stacking, helps to coherently stack the prestack migrated sections to produce a more highly resolved composite migrated section. Numerical results show that these procedures are capable of eliminating a fault-like artifact from the conventionally processed VSP migrated section.
