Abstract

"PROCESSOS PARA DESINTEGRAR A TORTA DO FILTRO EM UMA FORMAçãO SUBTERRáNEA, E PARA IMPEDIR O DANO àS TELAS E OUTRO EQUIPAMENTO SUBTERRáANEO DURANTE A COLOCAçãO EM UMA FORMAçãO SUBTERRáNEA, TELA OU OUTRO EQUIPAMENTO SUBTERRáNEO, E, USO DE UM POLìMERO SóLIDO" Um processo para desintegrar a torta de filtro em uma formação subterrânea, processo este que compreende: (i) incorporar em um fluido de tratamento um polímero sólido capaz de ser convertido por hidrólise em um ou mais ácidos orgânicos; (ii) introduzir o fluido de tratamento na formação subterrânea; e (iii) permitir que o polímero sólido hidrolise na presença de água para produzir ácido orgânico tal que o material solúvel em ácido dentro da torta de filtro ou formação adjacente seja dissolvido.
