U.S. Silica has a long and successful history of supplying finely ground crystalline silica to the oil & gas market. The physical and chemical properties associated with our ground silica products make them ideally suited for use in oil and gas zonal isolation. The primary application in zonal isolation is a cement additive that slows the hydration of the slurry in high temperature environments (hydration retardation) and enhances long-term performance of the cement sheath or wellbore plug. Furthermore, enhanced long-term performance of the cement is achieved when finely ground crystalline silica is admixed with certain other cement additives. In selected hydraulic fracturing applications, fine ground silica can also be used as a fluid-loss control additive in hydraulic fracturing fluids to improve the volumetric efficiency.
