摘要： 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.

摘要： A method of providing a viscous emulsion at a subterranean location accessible via a wellbore, begins by providing an aqueous/aqueous emulsion comprising two aqueous solutions which, at surface temperature and pressure, are able to co-exist as separate aqueous phases in contact with each other. The two phases contain respective solutes which are sufficiently incompatible that they cause phase separation. The dispersed phase is rich in one solute, which may be a thickening polymer, while continuous phase is rich in a second solute, which may comprise surfactant. A hydrophobic liquid is dispersed in this emulsion to become the dispersed phase of a viscous emulsion whose continuous phase is provided by the aqueous/aqueous emulsion. The hydrophobic liquid and the aqueous/aqueous emulsion may be pumped separately down the wellbore to the subterranean location, and allowed to mix there so as to form the viscous emulsion at the subterranean location. On mixing, surfactant from the aqueous/aqueous emulsion may migrate to the oil/water interface, allowing the aqueous phases to become one phase with the result that the emulsion is further thickened by any thickening polymer in its composition. Even more thickening can be achieved by crosslinking the thickening polymer.

摘要： A method of plugging a fracture in a subterranean formation which includes placing into the fracture a composition comprising microspheres or microbeads, wherein the microspheres are created by surface crosslinking of droplets in a water-in-water emulsion. Such microspheres may form a filter cake in the formation. The microspheres may include a chemical agent to be released when the microspheres dissolve.
