Resumo:
The seismic stacking aims to simulate a survey of zero offset and is often applied in multiple coverage seismic data processing. There are several methods of seismic imaging that have gained importance recently in order to overcome limitations of conventional stacking Common Midpoint concept, emphasizing, the methods of seismic stacking Common- Reflection -Surface ( CRS ), Multifocusing ( MF ) and the recent Nonhyperbolic CRS. The simulation of a seismic section zero offset ( ZO ), based on multi coverage seismic data is a standard imaging method used in seismic processing to reduce the amount of data and to increases the signal/noise ratio. In this work, the performances of these approaches transit times, hyperbolic and non- hyperbolic, were tested on synthetic data to simulate seismic sections zero offset ( ZO ) and to verify their recovery shape behavior and the amplitude of ZO simulated traces.
