Abstract: A gel mixing system that employs a dynamic diffuser for quickly removing the air from the fluid as the fluid exits a traditional gel mixer and employs progressive dilution of the gel in a series of hydration tanks to maximize hydration time without allowing the gel to become so viscous that it is not easily diluted or pumped.

Progressive dilution of the gel increases residence time of the gel in the tanks and results in longer hydration time in the limited tank space available, resulting in continuous production of gel that is almost fully hydrated when it is pumped to the fracturing blender and subsequently to the well bore without the need for an increase in the volume of the hydration tanks.

Abstract: Continuous stream ratio blending of two or more liquids. Each stream flow is time synchronized to all others and turned on and off to dose precise ratios into a constant pressure streams combining chamber. Combined on-off flows constitute a net flow rate exceeding some maximum continuous flow demand for the blended liquids. Dosed streams are pumped from the streams combining chamber at a rate matching their inflow, then through a mixing element into a finished blend tank. Use of a constant pressure streams combining chamber feeding a mix pump allows decoupling of individual streams ratio dosing flows and pressures one from another and from the combined stream. Blended liquid is available on demand as a continuous stream from the level controlled finished blend tank. The level sensor automatically starts and stops blended flow into the tank. Streams flow can be stopped upon completion of any dose cycle.
