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.

Zero-valent metal suspension in non-aqueous phase for water remediation

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.

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.
