Abstract

métodos para desviar o ácido em uma formação subterrânea contendo hidrocarboneto são descritos. os métodos incluem injetar um agente de desvio de ácido compreendendo uma poli-hidróxieteramina ramificada solúvel ou dispersável em água e injetar uma solução de ácido dentro do poço que está em contato com a formação subterrânea contendo hidrocarboneto. de preferência, a solução de ácido é desviada para uma zona da formação que tem uma permeabilidade para fluido mais baixa do que a de uma zona adjacente. este processo melhora a permeabilidade da formação subterrânea contendo hidrocarboneto para hidrocarbonetos enquanto diminui a permeabilidade da formação para água ou salmoura.
