Hydraulic fracturing fluids commonly consist of water, ‘proppants’ and chemical additives that open, enlarge and maintain fractures within the rock formation. The proppants – sand, ceramic pellets or other small incompressible particles – hold the newly created fracture open. The fracture widths are generally equal to a few diameters of the grains used in the […]

Stannous chloride solution has been gaining significant popularity as an iron reducing agent (IRA). Strong reducing agents easily lose (or donate) electrons. An atom with a relatively large atomic radius tends to be […]
