No. of bitstreams: 1 438673.pdf: 13692914 bytes, checksum: 3eac0c3d5df974b8965fd601f06ddf20 (MD5) Previous issue date: 2012-03-27 / Finding oil is a hard task that requires large amounts of information and resources. Along decades of research, geoscientists from Petrobras have accumulated great amout of data. Therefore, in petroleum geology other sources of important data are generally dispersed and have many forms of representation. This Master Thesis reports the creation of a database that stored various geophysical, paleogeographic and paleoclimatic data from the South Atlantic. Great part of these data were extracted from stratigraphic charts, converted, and stored as a numeric model. This model is the result of an aggregation of data from the Brazilian Sedimentary Basins and the creation of an algorithm solution able to map collected data at the designated geographical area. These data cover the past 140 millions years. The 140 millions of years correspond to a drift period of the South American Plate from the African west coast to the present location. During this drift several natural changes happened in the Ocean Sedimentary Basins until they reached the actual state. The grouping of these data enhances the potential to knowledge discovery on the factors necessary for the deposit of organic matter and oil generation, in consequence, these new factors may improve the chances of finding oil. / Encontrar petr?leo ? uma tarefa dif?cil que requer grandes quantidades de informa??es e recursos. Ao longo de d?cadas de pesquisa, os ge?logos da Petrobras acumularam grandes quantidades de dados. Al?m disso, na geologia do petr?leo outras fontes de dados s?o importantes, fontes estas, que em geral est?o dispersas e possuem v?rias formas de represen??o. Esta disserta??o relata a cria??o de um banco de dados que agrega diversos dados de origem paleoclim?tica e paleogeogr?fica provenientes do Atl?ntico Sul. Grande parte destes dados foram extra?dos de cartas estratigr?ficas, convertidos e armazenados em forma de um modelo num?rico. Modelo este, que ? resultado de agrega??es de dados provenientes das bacias sedimentares brasileiras e da cria??o de uma solu??o algor?tmica capaz de mapear os dados coletados ao longo da ?rea designada. Estes dados s?o relativos a um per?odo de tempo entre a idade geol?gica atual at? 140 milh?es de anos atr?s. Os 140 milh?es de anos correspondem ao per?odo de deslocamento do continente Sul-Americano desde a costa da ?frica at? a posi??o atual. Durante esse deslocamento houveram diversas mudan?as naturais nas bacias sedimentares oce?nicas at? chegarem ao estado atual. O grupamento destes dados potencializa a descoberta de conhecimento relativo aos fatores necess?rios para a deposi??o de mat?ria org?nica e gera??o de petr?leo no fundo do mar, assim, estes novos fatores podem vir a melhorar as probabilidades de descoberta de petr?leo.
