Abstract: The present subject matter illustrates a zero-valent metal suspension in non-aqueous phase. The suspension comprises 41 wt. % of a plurality of zero-valent iron particles; 0.1 wt % of a surfactant; 36 wt. % of an oil; and 23 wt. % of a thickening agent.

Abstract: A viscoelastic emulsion formed by combining at least one extended surfactant, a salt (e.g., brine), an oil, such as crude oil, diesel, kerosene, or a vegetable oil, and water, into a mixture comprising an oil-starved Winsor III microemulsion into which excess oil is dispersed. The viscoelastic emulsion may be combined with a proppant to form a fracking fluid. The viscoelastic emulsion may be used in various reservoir applications, such as hydraulic fracturing, or flooding for enhanced tertiary oil recovery, and in other applications such as, but not limited to, environmental remediation, or formation of consumer products.

Abstract: Compositions of nanoparticle-based stimulation fluids and methods of use for acid diversion from high permeability zones into low permeability zones to achieve deep penetration of wormholes in subterranean formations, such as carbonate formations. Certain embodiments include a gel precursor composition comprising metal oxide nanoparticles, such as silicon dioxide nanoparticles as a gelling agent, and magnesium chloride.

Abstract: The present subject matter illustrates a method for accelerated in-situ chemical reduction of subsoil matter. The method comprises supplying a mixture comprising ferrous sulfide into soil pathways to biologically react with dissolved contaminates in the groundwater. Further, an organic hydrogen donor is supplied into the soil-pathways to produce anerobic-conditions to cause indigenous anaerobic bacteria to biodegrade residual concentrations of the contaminates.

Abstract: Enhanced recovery of hydrocarbons from a subterranean reservoir injects a gaseous reactant and a dispersion of oil, water, and nano-hybrid catalysts through an injection well into a subterranean formation. The combination of the dispersion and gaseous reactant(s) forms a stabilized foam within the subterranean formation. When the foam reaches an oil-water inter-face, the nanohybrid catalysts catalytically partially oxidize the hydrocarbons present at the oil-water interface thereby increasing the capillary number and decreasing the interfacial tension at the oil-water interface.

Abstract: A binary or ternary surfactant mixture for use in enhanced oil recovery within a reservoir having total dissolved solids greater than approximately 80,000 parts per million (i.e., heavy to extreme brine conditions) includes at least two of a propoxylated/ethoxylated alcohol sulfate, an ethoxylated alcohol sulfate, and a monoalkyl or dialkyl diphenyloxide disulfonate. The surfactant mixture is used without alcohol, which is unnecessary to maintain solution stability and good coalescence rates and thus improves compatibility with polymers added to improve the mobility ratio. During testing, exceptional solution stability, excellent oil recovery capability, and good compatibility was observed with these surfactant blends. The mixtures are effective at concentrations below 1% and as low as 0.1% by weight.

Abstract: The present invention relates to the removal of subsurface contaminants and methods of using same. In more particular, but not by way of limitation, the present invention relates to an integrated method for remediating subsurface contaminants through the use of a low concentration surfactant solution (and methods of making and using novel surfactant solutions) followed by an abiotic polishing process to thereafter achieve a substantially reduced subsurface contaminant concentration that surfactant flushing alone cannot achieve. The present invention is focused on remediation of high viscosity hydrocarbons, such as heating oils or coal tars, with a combination of pre-injection of bio-co-solvent and surfactant (and polymer) flush approach.

Abstract: Surfactant systems are provided that, upon contact with an oil, can produce a Windsor Type III middle phase microemulsion at a total surfactant concentration of 1.5% to 1.0% or less based on the weight of water in the surfactant system, without the need for a cosolvent or linking molecule. The microemulsions can have a separation time less than about 2 hours and even less than about 15 minutes.
