    Abstract: A portable well treating fluid mixing system includes: a supply tank having an inlet receiving pneumatically conveyed dry treating material; a cyclone separator having an inlet coupled to the supply tank and receiving dust laden air from the supply tank, and having a first outlet venting clean air and having a second outlet venting solids; a collection container having a first inlet coupled to the cyclone separator second outlet and receiving solids from the cyclone separator and having an outlet; and, a pump having an inlet coupled to the collection container outlet and a pump outlet coupled to the supply tank. In operation, the system continuously conveys dust from the collection container back into the supply tank to maintain the separator in proper operating condition and minimizes venting of dust during the transfer of material to the supply tank.

    Abstract: The present invention relates to a method and system for hydrating a gel for treating a wellbore penetrating a subterranean formation. The method includes directing a base fluid through an inlet into a mixer having an inner chamber housing a plurality of impellors extending radially from and rotating about a hub, causing a centrifugal motion of the base fluid, feeding a quantity of gel into the mixer, mixing the gel with the base fluid and discharging the now-hydrated gel from the inner chamber through an outlet of the mixer. A prewetting device may also be used. Thereafter, a variety of additives may be added to the gel fluid mix to form a fluid treatment to be introduced into a subterranean formation.

    Abstract: An apparatus for mixing a fluid includes a mixing tub having a substantially circular horizontal cross-sectional shape, and an agitator assembly associated with the mixing tub. The agitator assembly includes a drive shaft having upper and lower agitators attached thereto. The drive shaft is located within the tub and has a substantially vertically oriented axis of rotation. The lower agitator moves fluid generally downward through a radially inner cross-sectional area defined within a first radius swept by the lower agitator. The upper agitator moves fluid within the first radius generally radially outward as that fluid is moved generally downward by the lower agitator, and moves fluid outside the first radius generally upward. A plurality of foraminous baffles are mounted within the tub for reducing rotational motion of the slurry within the tub about the generally vertical axis of the agitator shaft.
