Abstract: Methods are disclosed for dispersing nanoparticles in solvents, involving the use of a cationic species and an anionic species, where at least one of the ionic species is soluble in the nonpolar solvent and the other ionic species has a relatively strong affinity for the surface of the nanoparticles. The cationic species and the anionic species together form a cluster of ion pairs shielding the nanoparticles and enhancing their dispersibility in the nonpolar solvent.

Abstract: Methods are disclosed for emplacing a gel-form material in a porous subterranean formation, such as a hydrocarbon reservoir. The material is formed by admixing solid nanoparticles with gelation supporting amounts of surfactants or ionic species, such as ionic species of the kind that form ionic liquids. The nanoparticle to ion ratio may be selected, in combination with selecting the components of the gel-form material, so that the rheological and gelation properties of the gel-form material are adapted for a particular use, for example forming a fluid flow barrier in a reservoir.

Abstract: Processes are provided for conformance control in an enhanced oil recovery operation. These processes may for example provide for the use of cellulose nanocrystals (CNCs), for example desulfated CNCs, or chitin nanoparticles, for example having an average maximum dimension of ≤1 μm. These CNCs or chitin nanoparticles may be used to generate a CNC-stabilized oil in water emulsion, which may then be injecting into a zone of a porous subsurface formation. The injected CNC or chitin-stabilized emulsion may be allowed to form strong droplet networks with by resting in situ in the zone of the porous subsurface formation, so as to increase the viscosity of the rested injected CNC or chitin-stabilized emulsion. These emulsions may be used as a selective phase blocking agent or relative permeability modifier, as the strength of the droplet network is governed by the dielectric constant of the surrounding fluid.

Abstract: An example a method of manufacturing a film is provided. The method involves dissolving a backbone material in a non-aqueous solvent to form a non-aqueous solution. The method further involves adding the non-aqueous solution to an aqueous solution to form a liquid-liquid interface and injecting a particulate proximate to the liquid-liquid interface the non-aqueous solution is then evaporated to form a film containing the particulate. The film may be used in devices such as sensor devices for detecting hydrocarbons.
