Abstract
Patente de Invenção: <B>"PROCESSO PARA A CONSOLIDAçãO DE AREIA"<D>. Processo para a consolidação de areia em um poço que produza fluidos, em particular petróleo e/ou gás, compreendendo as seguintes etapas: 1) pré-lavagem opcional com uma solução aquosa de sais inorgânicos, de preferência KCl; 2) injeção na formação de um agente consolidante constituído essencialmente de uma solução aquosa de silicato de sódio em água. 3) lavagem com um gás inerte, de preferência nitrogênio, da formação tratada como na etapa (2) até que o excesso de agente consolidante e de água injetada na etapa (2) tenha sido removido. 4) introdução subseq³ente, na formação assim tratada, de uma solução aquosa de um ácido tendo um pKa de entre 3 e 10 a 25°C, de preferência selecionada a partir de cloreto de amónio e ácido acético.
