Abstract
A system for producing homogenized oil field gel including a power unit, a control system, a feed tank, a hopper, and a piping assembly that includes inlet and outlet manifolds, centrifugal pumps, and metering devices for filling the feed tank and handling a discharge of oilfield gel. The system further includes a powder hydration component and liquid chemical equipment. The method for producing homogenized oil field gel includes a guar powder procedure including a controlled sequence for starting and stopping a venturi mixer in a hydration unit. The method for producing homogenized oil field gel further includes a liquefied gel concentrate procedure including a metering and chemical injection procedure for mixing a liquefied gel concentrate.
Claims17
A system for producing oil field gel comprising:
- a power unit comprising an engine and one or more pumps;
- a control system;
- a feed tank comprising a plurality of chambers;
- a hopper;
- a piping assembly comprising inlet and outlet manifolds, centrifugal pumps, and metering devices for filling the feed tank and handling a discharge of oilfield gel;
- and
- a powder hydration component comprising a venturi mixing system.
A method for producing oil field gel comprising:
- metering dry guar powder using an agitated hopper and a metering dispenser;
- dispensing known volumes of guar powder to a pickup funnel;
- hydrating the guar powder using a hydration tank, wherein the hydration tank comprises a reservoir of fresh water;
- supplying water from the reservoir by a first centrifugal pump into a first chamber;
- delivering water to an eductor device by a second centrifugal pump creating a vacuum via the eductor device forcing enough water through the system;
- closing a vacuum interrupter valve thereby creating a vacuum in a powder conveyance line;
- delivering powder to the pickup funnel by the dispenser;
- hydrating the powder creating gel;
- and
- discharging the gel into a second chamber of the hydration tank.
The method according to claim 14, wherein the hydration unit further comprises a venturi mixing system.
The method according to claim 14, wherein the hydration unit further comprises a control system.
