Abstract
Compositions and methods of preparation and use for controlled release solid scale inhibitors used in hydraulic fracturing operations in oil and gas wells. The controlled release scale inhibitors comprise amorphous glass which is a reaction product of a phosphorus-containing compound, a calcium-containing compound, a magnesium-containing compound and base. The composition has a predetermined dissolution rate for controlled release of scale inhibitors in induced hydraulic fractures in hydraulic fracturing treatment of oil or gas wells.
