Title (EN) BREAKING THE RHEOLOGY OF A WELLBORE FLUID BY CREATING PHASE SEPARATION
(FR) RUPTURE DE LA RHÉOLOGIE D'UN FLUIDE DE TRAITEMENT DE PUITS DE FORAGE PAR CRÉATION D'UNE SÉPARATION DE PHASES
Abstract:
(EN) Embodiments of this invention relate to compositions and methods of treating a subterranean formation penetrated by a well bore including introducing a rheological polymer into a subterranean formation, introducing a partitioning agent into a subterranean formation and forming a heterogeneous mixture comprising a dispersed rheological polymer-rich phase and a partitioning agent-rich phase, wherein the viscosity of the mixture is lower than the viscosity of the mixture when no partitioning agent is present. Embodiments of this invention relate to compositions and methods of treating a surface in contact with a wellbore and/or a subterranean formation penetrated by a well bore including forming a heterogeneous mixture comprising a dispersed rheological polymer-rich phase and a partitioning agent-rich phase at the surface of the subterranean formation, and introducing the mixture into a subterranean formation, wherein the viscosity of the mixture within the subterranean formation is lower than the viscosity of the mixture when no partitioning agent is present and wherein the viscosity of the mixture within the subterranean formation is lower than the viscosity of the mixture when the mixture is formed at the surface of the subterranean formation.
(FR) Des modes de réalisation de cette invention portent sur des compositions et des procédés de traitement d'une formation souterraine pénétrée par un puits de forage comprenant l'introduction d'un polymère rhéologique dans une formation souterraine, l'introduction d'un agent de séparation dans une formation souterraine et la formation d'un mélange hétérogène comprenant une phase dispersée riche en polymère rhéologique et une phase riche en agent de séparation, la viscosité du mélange étant inférieure à la viscosité du mélange lorsque aucun agent de séparation n'est présent.
