Indeed some algorithms which can exempt the stack process (pre-stack migration). For this job, it was selected, between all available algorithms, the Kirchhoff’s method and Stolt’s method time migration, with an issue to discuss their applicability in 2D seismic data from Parnaíba’s basin. That discussion approaches their practicality, hardiness, used parameters and the comparison between the results. The data was 1000 shots with maximum coverage (210), from line 001 of project 0295_ANP_2D_PARNAIBA, from Agência Nacional do Petróleo Gás Natural e Biocombustíveis (ANP). It was processed using the software Promax from Landmark Graphics Corporation, company from Halliburton Ltda., following the conventional processing flux (CMP technique – pós-stack migration) to migration steps: Production of Kirchhoff time migrated section and Stolt time migrated section. The behaviors from reflectors were less deep and less lateral velocity variations and some regions with normal failing. The quality of Kirchhoff time migrated section was superior, despite the quickness of Stolt’s method, giving the migrated section with a half of processing time used by Kirchhoff’s methodology.Acesso AbertoMétodo de reflexão sísmicaInversão (Geofísica)Prospecção – Métodos geofísicosCNPQ::CIENCIAS EXATAS E DA TERRA::GEOCIENCIAS::GEOFISICA::SENSORIAMENTO REMOTOTrabalho de Curso - Graduação - Monografia
