  • High demand for sands Separation Solutions

    High demand for sands As oil prices rise to all time highs, producers search for means to increase production in existing wells, and exploit new oil and gas fields, which only a few years ago were not economically viable. This trend to maximize production has caused an unprecedented demand for hydraulic fracturing sand (frac sand).
