摘要： A water-based wellbore treatment fluid contains: one or more viscoelastic-gelling carboxylic acids and/or alkali metal salts thereof; and one or more solubilising alkylolamines. The carboxylic acids and/or alkali metal salts and the alkylolamines are present in the fluid in respective amounts such that, at 25° C., the alkylolamines solubilise a sufficient portion of the carboxylic acids and/or alkali metal salts to render the fluid viscoelastic. A remaining portion of the carboxylic acids and/or alkali metal salts forms a suspension of solid particulates in the fluid.

摘要： The present invention provides aqueous viscoelastic compositions comprising a cleavable anionic surfactant which is a sulphonate and possibly also an electrolyte. The cleavable surfactants useful in the present invention comprise a chemical bond, which is capable of being broken under appropriate conditions, to produce oil soluble and water soluble products typically having no interfacial properties and surface activity compared with the original surfactant molecule. Further, the rheological properties of the aqueous viscoelastic composition are usually altered upon cleavage of the cleavable surfactant generally resulting in the elimination of the viscosifying, viscoelastic and surfactant properties of the composition. Aqueous viscoelastic compositions in accordance with the present invention are suitable for use in oil-field applications, particularly for hydraulic fracturing of subterranean formations. Thus, the present invention also relates to a wellbore service fluid and a method of fracturing a subterranean formation.

摘要： Delivery of a substance to a subterranean location is achieved by suspending the substance as nanoparticles in a carrier fluid in which the substance is insoluble. First a dispersible powder composition, is formed by dissolving the substance in a solvent, emulsifying the resulting solution as the dispersed phase of an emulsion, and freeze-drying the emulsion to a powder. On mixing the powder with a fluid in which the substance is insoluble, the insoluble substance becomes a dispersion of nanoparticles which is pumped to the subterranean location. At the subterranean location a tracer dispersed as nanoparticles may migrate from injected water into hydrocarbon in a hydrocarbon reservoir. Another possibility is that the carrier fluid contains polymer and the dispersed nanoparticles comprise an agent which participates in cross-linking and consequent viscosification of the polymer at the subterranean location.

摘要： A method of processing an aqueous fluid produced from a wellbore in order to collect or remove a minor constituent therefrom, comprises adding one or more solutes to the aqueous fluid so as to form an aqueous mixture which separates into two aqueous phases in contact with each other, with a first solute present at a greater concentration in the larger, first aqueous phase than in the second aqueous phase and a second solute present at a greater concentration in the smaller, second aqueous phase than in the first aqueous phase; while the compositions of the two phases are such that the said minor constituent preferentially partitions into the smaller, second aqueous phase so that the concentration of that constituent in the smaller second phase exceeds its concentration in the larger first aqueous phase. The second aqueous phase with the said constituent concentrated therein is then separated from the first aqueous phase. The process may be used to concentrate a tracer, such as an organic dye, into a reduced volume which can be transported to a remote laboratory. The process may alternatively be used to remove a contaminant or other minor constituent, so as to allow the first aqueous phase to be put to use, eg for cementing or hydraulic fracturing.

摘要： Delivery of a substance to a subterranean location is achieved by suspending the substance as nanoparticles in a carrier fluid in which the substance is insoluble. The procedure may start by forming a dispersible powder composition, which is done by dissolving the substance in a solvent, emulsifying the resulting solution as the dispersed phase of an emulsion, and freeze-drying the emulsion to a powder. On mixing the powder with a fluid in which the substance is insoluble, any soluble constituents of the powder dissolve and the insoluble substance becomes a dispersion of nanoparticles of the substance. Then, the fluid containing the dispersed substance is pumped to the subterranean location. The dispersion of nanoparticles has surprising stability, facilitating transport to the subterranean location. At the subterranean location the dispersed nanoparticles may migrate into other fluid encountered there: more specifically a dispersed tracer substance may migrate from injected water into hydrocarbon in a hydrocarbon reservoir. Another possibility is that dispersion as nanoparticles enables interaction with other constituents of the fluid to be delayed until the subterranean location is reached: more specifically the fluid may contain polymer and the dispersed nanoparticles may comprise an agent which participates in cross-linking and consequent viscosification of the polymer.
