Abstract

UN METODO PARA REDUCIR LA PERMEABILIDAD DE UNA ZONA DE ALTA PERMEABILIDAD EN UN DEPOSITO DE ACEITE A ALTA TEMPERATURA, COMPRENDE: GELIFICABLE, ACTUANDO SOBRE LA SUPERFICIE Y EN CONDICIONES CONTROLADAS; TRO DEL DEPOSITO DE ACEITE A TRAVES DE UN POZO; TANCIALEMENTE LLENE LA ZONA DE ALTA PERMEABILIDAD QUE SE VA TRATAR; Y GUIENTE DESCENSO DE LA PERMEABLIDAD EN LA CITADA ZONA DE ALTA PERMEABILIDAD. ESTANDO ESENCIALMENTE CARACTERIZADO PORQUE LA SOLUCION GELIFICABLE ES UN SOLUCION ACUOSA CONTENIENDO UN AGENTE DE DEGRADACION DE IONES DE CR(III), Y UN POLIMERO ORGANICO, SOLUBLE EN AGUA Y DEGRADABLE POR EL EFECTO DEL CITADO AGENTE DE DEGRADACION, LA CITADA SOLUCION ESTANDO LIBRE, O SUSTANCIALMENTE LIBRE DE AGLUTINANTES PARA EL AGENTE DE DEGRADACION, Y TENIENDO UN PH AJUSTADO A UN VALOR DENTRO DE LA ESCALA DE UNO 5''5 A 5''5, SEGUN EL TIEMPO DESEADO DE GELIFICACION.
