Um processo de aquisição e mapeamento de dados para as bacias sedimentares marginais brasileiras

Abstract

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.
