    DESCRIPTION

    This Northern White monocrystalline alpha-quartz proppant is derived from the St. Peter

    and Wonewoc formations and processed and sized at the U.S. Silica plants in Illinois and

    Wisconsin. The extremely durable proppant exhibits exceptional strength, integrity and

    purity, and will not degrade or dissolve during handling and pumping associated with

    normal fracturing operations.

    ADVANTAGES AND BENEFITS

    • Proppant specific gravity of 2.65 enables maximum suspension and lateral fracture placement

    • Compatible with all hydraulic fracturing chemicals

    • High-quality Krumbein Factors (roundness and sphericity) ensure optimum downhole

    porosity and permeability, and thus, conductivity

    • Excellent crush resistant classification or K-Value

    • Meets or exceeds ISO 13503-2 and API RP 19C specifications for particle distribution,

    roundness and sphericity, turbidity, acid solubility and crush resistance

    APPLICATIONS

    • All sandstone and fractured shale formations requiring high-strength

    alpha-quartz proppants• Recommended for formations with net closure stresses up to 6,000 psi

    LONG-TERM CONDUCTIVIT

    Long-term conductivity is

    a measure of the hydraulic

    fracture’s ability to allow flow.

    It is a multiple of the

    permeability of the proppant

    pack in millidarcys and the

    width of the proppant pack

    measured in feet.

    LONG-TERM PERMEABILITY

    Long-term permeability is a

    measure of a porous medium’

    ability to flow measured in

    Darcys or fractions thereof.

    It is a function of the cross-

    sectional area open to flow,

    the differential pressure due

    to flow and the viscosity of the

    flowing medium.
