Superior Product Performance

No matter what the application, our proppants meet or exceed ISO 13503-2 and API RP 19C specifications for particle distribution, roundness and sphericity, turbidity, acid solubility, and crush resistance—so you never have to worry about how your product will perform under pressure.

Our proppants have a history of premium performance in unconventional reservoirs, including Tight Gas, Coal Bed Methane, Shale Gas and Liquids—and we’ve expanded our whole-grain silica product line to service all flow regimes.

Raw Sand and Resin-Coated Sand Proppants

Our Northern White proppants set the industry standard for quality and consistency for whole-grain α-quartz (monocrystalline silica) proppants. Exhibiting exceptional strength, it will not degrade or dissolve during fracturing operations. And now, we’re proud to introduce our newest resin-coated proppant from Coated Sand Solutions—engineered especially for high-pressure/high-temperature and viscous regions.
