Resumo:
The current work studied the effect of the anisotropy in the step of analysis of seismic data processing speed for VTI media. A comparative analysis was performed between equations of correction isotropic and anisotropic normal moveout using an anisotropic synthetic data. The unix seismic free package was used for the realization of the speeds analysis step, then made up graphs that describe anisotropy behavior as a function of the source-receiver distance. That allowed concluded that small distance from source-receiver there was no influence of anisotropy in the retification of data. However for big distance from source-receiver is necessary the incorporation of anisotropy. In this way, this work is a form of quantification the residual moveout.
