Abstract

Una composición de fluido para el tratamiento de pozos que comprende un solvente (tal como agua), un polímero soluble o que se hidrata en el solvente, un agente de entrecruzamiento, un agente de ruptura inorgánico, y un compuesto tipo éster. Preferiblemente el polímero que se puede hidratar es un polisacárido, tal como galactomanamo, celulosa, o derivados de los mismos. El agente de entrecruzamiento es preferiblemente un borato, un titanato, o un compuesto que contiene circonio. El agente de ruptura inorgánico es preferiblemente un agente oxidante de base metálica, tal como un agente oxidante en base a un metal alcalino térreo o a un metal de transición. El compuesto tipo éster es preferiblemente un éster de ácido policarboxílico, tal como un éster de oxalato, citrato, o etiléndiamino tetraacetato. Un ejemplo de compuesto tipo éster apropiado es acetil citrato de trietilo.
