<p>A treatment fluid for a subterranean formation includes a carrier fluid and an amount of particles including a granular scale inhibitor. The carrier fluid includes a hydratable gel fluid, a crosslinked gel fluid, an acid-based fluid, an oil-based fluid, and/or a visco-elastic surfactant. The particles include a proppant impregnated with the scale inhibitor, a solid particle formed largely from the scale inhibitor, or both. The proppant includes scale inhibitor adsorbed on porous surfaces within the proppant, and/or a porous proppant with scale inhibitor embedded in the bulk porosity of the proppant. The scale inhibitor is present in an amount between about 1% and 5% of a total weight of particles. The particles include scale inhibitor at a sufficient concentration and dissolution rate to provide acceptable scale inhibitor concentrations in produced fluids for production volumes exceeding 500 pore volumes.</p> |
