Abstract

Un pozo de petróleo o gas que penetra una formación subterránea, tal como una formación de carbonato, es tratado con un fluido de tratamiento de pozo que contiene un éster orgánico. El fluido puede ser una emulsión de aceite en agua del éster orgánico y un emulsionante o una solución homogénea de éster orgánico y una solución de agua/solvente mutuo. Se produce ácido in situ por hidrólisis del éster orgánico.
