Item Acesso aberto (Open Access) Aplicação de Well-Tie no imageamento de uma área da bacia Tumbes-progresso(Universidade Federal do Pará, 2014-08-29) CHAGAS, Tiago Paulo Câncio das; SILVA, Carolina Barros da; http://lattes.cnpq.br/5306784916926352; GOMES, Ellen de Nazaré Souza; http://lattes.cnpq.br/1134403454849660Geological areas with large lateral velocity variations, such as in areas with faults and salt domes are complex areas, in general, seismic imaging time is limited. In these cases, the seismic imaging depth can provide better results. However, a velocity model is needed in depth with precision, which is not an easy task. An alternative to estimate the depth velocity model is provided by Well-tie technique. With the calibration of the synthetic trace data obtained from wells, seismic section with the depth map of velocity can be obtained through the time-depth curve. In this study, we used the Well-Tie to improve the model of RMS velocity obtained from the processing of seismic data. The updated velocity model was converted to depth and used to generate an in depth migrated seismic image of a region of Tumbes Basin-Progress.
