Abstract

"MéTODO PARA DETERMINAçãO DE UMA PROPRIEDADE DE FLUIDOS EM FORMAçõES LOCALIZADAS EM TORNO DE UM FURO PERFURADO NO SOLO". Trata-se de um método para determinação de uma propriedade de fluidos em formações geológicas localizadas em torno de um furo perfurado no solo, que inclui as seguintes etapas: produção, a partir de medições realizadas em uma multiplicidade de amostras de fluido, de uma base de dados de valores de treinamento de propriedades de fluido armazenados relativamente a valores treinamento de medição de fluido armazenados; derivação, da base de dados, de parâmetros de função de base radial; derivação de valores de medição de fluido de formação geológica; e determinação, mediante uso de interpolação de função de base radial, da propriedade de fluidos de formação geológica a partir de valores armazenados na base de dados, dos parâmetros, e dos valores derivados de medição de fluido de formação geológica.
