Title (EN) STABILIZING BIPHASIC CONCENTRATES THROUGH THE ADDITION OF SMALL AMOUNTS OF HIGH MOLECULAR WEIGHT POLYELECTROLYTES
(FR) STABILISATION DE CONCENTRÉS BIPHASIQUES GRÂCE À L'AJOUT DE PETITES QUANTITÉS DE POLYÉLECTROLYTES DE MASSE MOLÉCULAIRE ÉLEVÉE
Abstract:
(EN) This invention relates to compositions and methods of treating a subterranean formation penetrated by a well bore including providing a treatment composition comprising a rheological polymer, a partitioning agent, a charged polyelectrolyte, and a first liquid medium, forming a stabilized heterogeneous mixture comprising a dispersed rheological polymer-rich phase and a partitioning agent-rich phase, and injecting the treatment fluid into the well bore. The invention relates to methods and compositions for preparing a well treatment fluid, including mixing polyethylene glycol partitioning agent, a charged polyelectrolyte, a first aqueous medium, and one or more rheological polymers selected from the group consisting of guar, modified guar, cellulose, modified cellulose, heteropolysaccharide, heteropolysaccharide derivative, or polyacrylamide, to hydrate the one or more polymers and form a water-in-water emulsion, and mixing the water-in- water emulsion with a second aqueous medium to form a well treatment fluid.
(FR) Cette invention porte sur des compositions et des procédés de traitement d'une formation souterraine pénétrée par un puits de forage comprenant l'obtention d'une composition de traitement comprenant un polymère rhéologique, un agent de séparation, un polyélectrolyte chargé et un premier milieu liquide, la formation d'un mélange hétérogène stabilisé comprenant une phase dispersée riche en polymère rhéologique et une phase riche en agent de séparation, et l'injection du fluide de traitement dans le puits de forage. L'invention porte également sur des procédés et des compositions pour la préparation d'un fluide de traitement de puits, comprenant le mélange d'un agent de séparation à base de polyéthylèneglycol, d'un polyélectrolyte chargé, d'un premier milieu aqueux et d'un ou plusieurs polymères rhéologiques choisis dans le groupe constitué par la gomme de guar, la gomme de guar modifiée, la cellulose, la cellulose modifiée, un hétéropolysaccharide, un dérivé d'hétéropolysaccharide ou un polyacrylamide, pour hydrater ledit ou lesdits polymères et former une émulsion d'eau dans l'eau, et le mélange de l'émulsion d'eau dans l'eau avec un second milieu aqueux pour former un fluide de traitement de puits.
