Acesso em:.https://repositorio.ufpa.br/handle/2011/11441The application of coring techniques is usually carried out in a limited number of vertical wells drilled in an oil field, causing the rarefaction of facies descriptions and not allowing a realistic characterization of reservoirs. Increased production of hydrocarbons in an oil field is extremely important for the oil industry and deeply dependent on the knowledge of the reserves in accordance with their petrophysical properties, which vary depending on geological facies. A better description of facies may reflect more realistic estimates of hydrocarbon volumes. This dissertation presents an intelligent algorithm capable of producing the transport of geologic information produced by the facies analysis of cores to the non-cored wells in an oil field, through the design of a direct neural network trained to perform a mapping of geological information in terms of the physical properties registered in the well logs. The intelligent algorithm processes the result produced by the neural network through a depth coherence filter to locate the boundaries of the layers along the well trajectory. For all of our cases the intelligent algorithm presented results compatible with the core analysis and independent of the size of the training set.Acesso AbertoGeofísicaPerfilagem geofísica de poçosRedes neurais (Computação)Geofísica de poçoAlgoritmos inteligentesRede neural artificialWireline loggingIntelligent algorithmsArtificial neural networksDissertaçãoCNPQ::CIENCIAS EXATAS E DA TERRAAPLICAÇÃO E DESENVOLVIMENTO DE ALGORITMOS INTELIGENTES AO ESTUDO DE RESERVATÓRIOS DE HIDROCARBONETOSGEOFÍSICA DE POÇO
