Associação de Estatística Multivariada com Redes Neurais e Lógica Fuzzy para Identificação automática de litologias usando perfis de poço do Campo de Namorado na Bacia de Campos, Brasil

In search of the petroleum reservoir characterization, the first task executed is the identification of lithologies crossed by the well, which may be achieved through the analysis of core sampling. However, this method is considered expensive and lengthy. Another way is through the interpretation of well logs, which are calibrated with some data from core samples and then extrapolated to the entire field. Although the interpretation using well logs is considered more economic, in some cases, due to the mineralogical complexity of these rocks, satisfactory results are not attained. This fact is because of the use of conventional statistical or mathematical algorithms.
