Abstract

GéIS POLIMéRICOS INTERLIGADOS E USO DE TAIS GéIS POLIMéRICOS NA RECUPERAçãO DE HIDROCARBONETO. Uma composição inclui água tendo uma salinidade de pelo menos 1 ppt, pelo menos um polímero hidrofilico contendo grupos de amina primária (-NH~ 2~ e/ou secundária (-NHR) e pelo menos um sacarideo contendo uma função redutivel. Um método de mudar a permeabilidade de uma formação subterrânea inclui a etapa de injetar em uma formação subterrânea uma composição compreendendo água, pelo menos um polimero hidrofilico contendo pelo menos dois grupos que são independentemente o mesmo grupo de amina primária ou diferente ou um grupo de amina secundária e pelo menos um sacarideo contendo uma função redutível.
