Abstract: Fluids viscosified with viscoelastic surfactants (VESs) may have their viscosities affected (increased or reduced, e.g. gels broken) by the indirect or direct action of a composition that contains at least one fatty acid that has been affected, modified or reacted with an alkali metal base, an alkali earth metal base, ammonium base, and/or organic base compound, optionally with an alkali metal halide salt, an alkali earth metal halide salt, and/or an ammonium halide salt. The composition containing the resulting saponification product is believed to either act as a co-surfactant with the VES itself to increase viscosity and/or possibly by disaggregating or otherwise affecting the micellar structure of the VES-gelled fluid. In a specific, non-limiting instance, a brine fluid gelled with an amine oxide surfactant may have its viscosity broken with a composition containing naturally-occurring fatty acids in canola oil or corn oil affected with CaOH, MgOH, NaOH and the like.

Abstract: A method of slurrifying oil contaminated materials by introducing a microemulsion or microemulsion-forming surfactant(s) to the material and subjecting the mixture to suitable shear or mixing forces to suitably blend such mixtures. The method may be applied directly to wastes such as waste drill mud cuttings and muds, emulsions, sludges, or soil substrates contaminated with water and/or oil drilling fluids in order to both reduce the viscosity and improve the lubricity, wetting, and flow properties of the substrate.

Abstract: A water-insoluble liquid crystalline gel composed mainly of a water-soluble polymer, itself having a gelation function together with a liquid crystal formation function and having an optical property is produced. First, the water-soluble polymer is dissolved in water or an aqueous solution containing a salt(s) to prepare a polymer solution. Subsequently, this polymer solution is dialyzed in an aqueous solution containing a chemical crosslinking agent, thereby obtaining the gel having a liquid crystal structure and composed mainly of the water-soluble polymer. Said water soluble polymer is one or two or more polymers selected from the group consisting of water-soluble biopolymers, derivatives of these water-soluble biopolymers and water-soluble synthesized polymers. The water-soluble biopolymers are one or two or more polymers selected from the group consisting of nucleic acids, polysaccharides, proteins, modified proteins and polyamino acids.
