Caracterização de eletrofácies por meio de ferramentas estatísticas multivariadas

Abstract: This paper presents a method for electrofacies characterization which is based upon multivariate statistics analysis applied to well log data obtained from lithological classes identified in the core ResumoNesse artigo é apresentado um método de caracterização de eletrofácies com base em análises estatísticas multivariadas, o qual utiliza dados de perfis geofísicos de poços referentes às classes litológicas identificadas nos testemunhos desses poços. Como exemplo de aplicação, utiliza-se um conjunto de dados, … Show more

“…The cluster and discriminant analyses have shown good applicability in the processing and interpretation of well log data. In particular, many researchers have applied these techniques to identify and separate different litho-types and fluids in formations (Flexa et al, 2004;Rosa et al, 2008).…”

“…Diversos trabalhos técnicos foram realizados integrando informações de perfis de poço e de testemunhos. Rosa et al (2008) desenvolveram modelos de eletrofácies utilizando estatística multivariada. As distribuições dos tamanhos dos poros foram correlacionadas com os perfis por Carrasquilla & Franco (2014).…”

“…Many statistical multivariate methods like Principal Component Analysis (PCA) or Discriminant Analysis (DA) have been applied to analyse multiple geophysical well logs to produce lithofacies models (Flexa et al, 2004;Rosa et al, 2008;Sancevero et al, 2008). These methods together with the knowledge of petrophysical proprieties are often used in flow simulators of a petroleum field.…”
