Title (EN) VISCOSIFICATION AND FOAMING OF POLYACRYLAMIDES
(FR) VISCOSIFICATION ET MOUSSAGE DE POLYACRYLAMIDES
Abstract: front page image
(EN)Embodiments of the invention relate to a method for treating a subterranean formation, comprising forming a fluid comprising polyacrylamide and a biopolymer and introducing the fluid to a subterranean formation wherein the polyacrylamide and biopolymer are selected to form the fluid with a longer foam half life and a higher viscosity than if only one polymer were selected. Embodiments of the invention relate to a method for treating a subterranean formation, comprising forming a fluid comprising polyacrylamide and a biopolymer and introducing the fluid to a subterranean formation wherein the polyacrylamide does not alter biopolymer crosslinking.
(FR)Des modes de réalisation de l'invention concernent un procédé de traitement d'une formation souterraine, consistant à former un fluide contenant un polyacrylamide et un biopolymère et à introduire ce fluide dans une formation souterraine, le polyacrylamide et le biopolymère étant sélectionnés pour former un fluide présentant une demi-vie de mousse plus longue et une viscosité plus élevée que si seulement un polymère avait été sélectionné. Des modes de réalisation de l'invention concernent un procédé de traitement d'une formation souterraine, consistant à former un fluide contenant un polyacrylamide et un biopolymère et à introduire le fluide dans une formation souterraine, le polyacrylamide ne modifiant pas la réticulation du biopolymère.
