Abstract

La presente invención se refiere a la estimulación de los pozos que penetran las formaciones subterráneas. Un método de grabado al ácido diferencial de la fractura subterránea en donde se proporciona la deposición no uniforme de un material de enmascaramiento sobre la cara o superficie de la fractura; el tratamiento subsiguiente mediante un ácido o un fluido reactivo genera un patrón de grabado al ácido heterogéneo sobre la superficie de la fractura, el patrón de grabado al ácido se ve influenciado grandemente por la geometría de colocación del material de enmascaramiento, tras el cierre estas irregularidades proporcionan una incompatibilidad de geometría que deja abierto el canal conductivo en la fractura.
