Abstract
PROCEDIMIENTO PARA OXIDAR UN CONTAMINANTE EN UNA FORMACION SUBTERRANEA PERMEABLE. SE REALIZA UN TRATAMIENTO PREVIO CON UN FLUIDO ACUOSO QUE CONTIENE UN CATALIZADOR DE DESCOMPOSICION DEL PEROXIDO DE HIDROGENO, UN AGENTE QUELANTE, UN ACTIVADOR DE RADICALES LIBRES SIENDO UNA SAL DE HIERRO O COBREO UNA SAL COMPLEJA DE HIERRO O COBRE. POSTERIORMENTE SE INTRODUCE UNA SOLUCION ACUOSA DE TRATAMIENTO, CONTENIENDO UNA CANTIDAD EFICAZ DE PEROXIDO DE HIDROGENO Y UN INTERVALO DE CONCENTRACION PREFERIBLE DE 0,5 AL 10%; UN AGENTE DE CONTROL DE MOVILIDAD DEL GRUPO DE MATERIALES POLIMEROS HIDRATABLES, MODIFICADORES INTERFACIALES Y AGENTES DESIFICADORES, MODIFICANDO LA CIRCULACION DE LA SOLUCION ACUOSA; COMO MATERIALES POLIMEROS HIDRATABLES: POLIACRILAMIDAS Y COPOLIMEROS DE POLIACRILAMIDA, SIENDO LA CANTIDAD A UTILIZAR EN RELACION AL GRADO DE VISCOSIDAD DESEADA; LOS MODIFICADORES INTERFACIALES USADOS SON LOS AGENTES TENSIOACTIVOS, USANDOSE DE 0,5 A 40 KG POR METRO CUBICO DE SOLUCION ACUOSA DE TRATAMIENTO; ENLA MISMA CANTIDAD SE UTILIZAN LAS SALES DE FOSFATO COMO AGENTE DENSIFICADOR.
