The stacked section has a better signal to noise ratio than the seismic data. In the conventional form, the seismic stacking is associated with CMP sort data, the velocity analysis, and the application of NMO and DMO correction. In other hand, simulate of zero offset section can be achieved throw automatic parameter estimation that select coherence measures in a CMP neighbor. On literature, there are many methodologies to accomplish the optimization parameters, in this Final Course Report (TCC), I implemented the Powell and Quasi-Newton optimization technique. These algorithms were tested to the CRS 2D method in a set of synthetic Marmousoft data. Numerical experiments indicate that both method are efficient, moreover, Powell method is more accurate to estimate parameters.Acesso AbertoGeofísicaEmpilhamento CMPEmpilhamento CRSOtimização PowellCNPQ::CIENCIAS EXATAS E DA TERRA::GEOCIENCIAS::GEOFISICATrabalho de Curso - Graduação - Monografia
