No. of bitstreams: 1 DanielleKSG_TESE_1-80.pdf: 3344366 bytes, checksum: 7b166fd0d1c9101001b02bd52c3b1b8d (MD5) Previous issue date: 2010-02-22 / Conselho Nacional de Desenvolvimento Cient?fico e Tecnol?gico / The increasing use of shallow seismic methods of high resolution, for investigations of geological problems, environmental or industrial, has impelled the development of techniques, flows and computational algorithms. The practice of applying techniques for processing this data, until recently it wasn t used and the interpretation of the data was made as they were acquired. In order to facilitate and contribute to the improvement of the practices adopted, was developed a free graphical application and open source, called OpenSeismic which is based on free software Seismic Un*x, widely used in the treatment of conventional seismic data used in the exploration of hydrocarbon reservoirs. The data used to validate the initiative were marine seismic data of high resolution, acquired by the laboratory of Geology and Marine Geophysics and Environmental Monitoring - GGEMMA, of the Federal University of Rio Grande do Norte UFRN, for the SISPLAT Project, located at the region of paleo-valley of the Rio Acu. These data were submitted to the processing flow developed by Gomes (2009), using the free software developed in this work, the OpenSeismic, as well other free software, the Seismic Un*x and the commercial software ProMAX, where despite its peculiarities has presented similar results / A crescente utiliza??o de m?todos de s?smica rasa de alta resolu??o, para investiga??es de problemas geol?gicos, impulsionou o desenvolvimento de t?cnicas, fluxos e algoritmos computacionais. A pr?tica de aplicar t?cnicas para tratamento desses dados, at? pouco tempo n?o era utilizada e a interpreta??o dos dados era feita da forma que eram adquiridos. Visando facilitar e contribuir para o aperfei?oamento dessas pr?ticas adotadas, desenvolveu-se uma aplica??o gr?fica livre e de codifica??o aberta, denominada OpenSeismic que tem como base o software livre Seismic Un*x, bastante utilizado no tratamento dos dados da s?smica convencional, utilizados na explora??o de reservat?rios de hidrocarbonetos. Os dados utilizados para validar a iniciativa, foram dados de s?smica marinha de alta resolu??o, adquiridos pelo laborat?rio de Geologia e Geof?sica Marinha e Monitoramento Ambiental GGEMMA, da Universidade Federal do Rio Grande do Norte UFRN, para o Projeto SISPLAT, tendo como localiza??o a regi?o do Paleovale do Rio A?u. Esses dados foram submetidos ao fluxo de processamento desenvolvido por Gomes (2009), utilizando os softwares livres OpenSeismic, Seismic Un*x e o software comercial ProMAX, onde apesar das suas particularidades pode-se observar resultados equivalentes
