Azimuth Preserved Trace Binning of 4D Seismic Data for Improved Repeatability

A-27 AZIMUTH PRESERVED TRACE BINNING OF 4D SEISMIC DATA FOR IMPROVED REPEATABILITY Abstract 1 During the processing of 4D seismic data it is vital to adequately compensate for the nonrepeatability that is a function of acquisition and processing effects. In this paper it is demonstrated that the seismic repeatability can be improved if an azimuth preserved trace binning methodology is implemented between base and monitor survey during the preprocessing stage. This improvement is illustrated using synthetic seismic data generated utilising real navigation data and a model of an isotropic medium. Different types of azimuth based trace binning can be done
