Abstract

resumo patente de invenção: "estimativa de saturação usando dados de mcsem e modelagem petrofísica estocástica". a invenção refere-se a um método para a estimativa de saturação usando dados de mcsem e modelos petrofísicos estocásticos por meio de quantificação da saturação média de água em um reservatório dada a resistência transversal (tr) obtida a partir dos dados de mcsem compreendendo as etapas a seguir: a) obtenção de dados de levantamento mcsem de uma região de interesse no subsolo, b) realização de uma inversão dos ditos dados de mcsem obtidos, c) subtração de uma tendência de resistividade de base dos ditos dados de inversão de mcsem da tendência de resistividade dos ditos dados de inversão por mcsem dentro um reservatório de hidrocarbonetos, d) estimativa da localização de uma anomalia nos dados de inversão de mcsem, e) estimativa da magnitude da resistência transversal associada a uma anomalia a partir dos dados de inversão de mcsem, f) estimativa de uma saturação média inicial do reservatório que corresponde à resistência transversal usando um modelo petrofísico estocástico e simulação de monte carlo que correlacionam parâmetros do reservatório à resistência transversal, e g) integração da distribuição de saturação obtida como uma função de resistências transversais sobre a distribuição assumida de resistências transversais para obter uma estimativa final da probabilidade de saturação de fluido.
