Abstract:
Pre-stack depth migration (PSDM) is applied to a 3D seismic survey from the Bowen Basin in QLD to improve imaging of shallow coal-seams which suffer from poor signal-to-noise caused by poor statics and velocities. Two different velocity fields are used as initial velocity models. The first is the PSTM velocity field and the second is created based on imaging reflections from the base of weathering.
