Title (EN) DEGRADABLE THERMOSETTING COMPOSITIONS FOR ENHANCED WELL PRODUCTION
(FR) COMPOSITIONS DÉGRADABLES THERMODURCISSABLES DESTINÉES À LA PRODUCTION AMÉLIORÉE DE PUITS
Abstract:
(EN) Methods of enhancing well production, including enhancing fluid flow by conductivity enhancement, diversion, and fluid-loss control, are described. The method of enhancing fluid flow includes introducing a fracturing fluid including resin-coated proppant particles into the formation; introducing (i) a thermosetting composition including one or more di- or tricarboxylic acids and one or more epoxidized fatty acid esters or (ii) thermoset particulates comprising an anhydride network of one or more epoxidized fatty acid esters cross-linked with one or more di- or tricarboxylic acids, into the formation; allowing the resin-coated proppant particles and (i) the thermosetting composition or (ii) the thermoset particulates to form a proppant matrix in a fracture; and allowing voids to form in the proppant matrix.
(FR) La présente invention concerne des procédés d’amélioration de la production de puits, comprenant l’amélioration de l’écoulement de fluide par l’amélioration de la conductivité, la déviation, et la régulation de perte de fluide. Le procédé d’amélioration de l’écoulement de fluide comprend l’introduction d’un fluide de fracturation comprenant des particules d’agent de soutènement enrobées de résine dans la formation ; l’introduction (i) d’une composition thermodurcissable comprenant un ou plusieurs acides di- ou tricarboxyliques et un ou plusieurs esters d’acide gras époxydés ou (ii) des particules thermodurcies comprenant un réseau anhydride d’un ou plusieurs esters d’acide gras époxydés réticulés avec un ou plusieurs acides di- ou tricarboxyliques, dans la formation ; permettant aux particules d’agent de soutènement enrobées de résine et (i) à la composition thermodurcissable ou (ii) aux particules thermodurcies de former une matrice d’agent de soutènement dans une fracture ; et de laisser des vides se former dans la matrice d’agent de soutènement.
