<p>The present invention relates to a method and system for hydrating a gel for treating a wellbore penetrating a subterranean formation. The system (200) includes a gel powder supply (240) connected to a mixer (250). A base fluid (235), such as water, is supplied to the mixer (250) by fluid inlet (230), and the mixed gel (25) is directed through outlet (270). The mix (250) includes a housing (210) having an inner chamber (220). The mixer (250) is powered by a power source (225) such as a motor. The mixer (250) is fed the powered gel (245) by the gel powder supply (240) through the powder inlet (242). The mixer (250) creates a suction, when in use, and draws the powered gel (245) through the inlet (242) and into the mixing chamber (220). A base fluid (235) is supplied to the mixer (250) through a base fluid inlet (230). The base fluid may be comprised of various fluids, but is preferably water based. The mixer employs an impeller (215) rotating on a hub (260) which spins on an axis, such as in a centrifugal pump, creating a centrifugal motion in the gel powder and base fluid. The mixer (250) efficiently mixes the powered gel (245) and base fluid (235) to create a hydrated gel fluid (265) which is directed from the mixer through outlet (270). The resulting gel fluid mix (265) may be further processed as desired, such as by the use of diffusers, separators, hydration tanks and the like.</p> |
