    摘要： Embodiments of this invention relate to compositions and methods of treating a subterranean formation penetrated by a well bore including introducing a Theological polymer into a subterranean formation, introducing a partitioning agent into a subterranean formation and forming a heterogeneous mixture comprising a dispersed Theological 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 Theological 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.

    摘要： A low viscosity wellbore polymer fluid gelling system comprising an aqueous medium and a water-in-water emulsion comprising a plurality of polymers or oligomers, including at least one removable polymer or oligomer, and at least one gelling polymer or oligomer, wherein said fluid has a low viscosity when injected, and the gelling polymer forms a gel downhole which has a storage modulus of at least about 60 Pa after the removable polymer is removed from the fluid. The invention also provides a method of isolating at least one zone of a subterranean formation penetrated by a wellbore, including the steps of preparing a water-in-water emulsion comprising a plurality of polymers or oligomers including at least one removable polymer or oligomer, and at least one gellable polymer or oligomer; combining the water-in-water emulsion with an aqueous medium to prepare a low viscosity polymer fluid; introducing the fluid into a zone in the formation, removing the at least one removable polymer or oligomer, and allowing a remaining gellable oligomer, polymer or polymers to form a gel, isolating the zone from at least one other zone in the formation.
