主权利要求
(US9145747) What is claimed: 1.  A method of mixing drilling fluids, the method comprising: injecting a drilling fluid into a high shear mixing unit; and   processing the drilling fluid with the high shear mixing unit, wherein the processing comprises:   forcing the drilling fluid through one or more stages of the high shear mixing unit, such that the drilling fluid enters a second stage proximate to an outer diameter of a first stage, the second stage having an outer diameter greater than the outer diameter of the first stage, wherein the one or more stages each comprise a rotor and a stator and the outer diameter of each stage is defined by the outer diameter of the stator. 2. The method of claim 1, further comprising: forcing the drilling fluid through a first rotor and a first stator of the first stage. 3. The method of claim 1, wherein the drilling fluid comprises at least one of a group of water-based drilling fluids, oil-based drilling fluids, and synthetic drilling fluids. 4. The method of claim 1, wherein the injecting further comprises injecting drilling fluid at a rate of up to 1000 gallons per minute into the high shear mixing unit. 5. The method of claim 1, further comprising: reinjecting the drilling fluid into the high shear mixing unit. 6. The method of claim 1, wherein the high shear mixing unit is disposed inline at a drilling site. 7. A method of processing drilling fluid at a drilling location, the method comprising: injecting drilling fluid into a high shear mixing unit;   forcing the drilling fluid through at least a first set of rotor teeth and corresponding stator teeth of a first stage of the high shear mixing unit, wherein the first stage has a first diameter;   contacting the drilling fluid against a sidewall of the high shear mixing unit;   forcing the drilling fluid down the sidewall of the high shear mixing unit to the second stage and out through at least a second set of rotor teeth and corresponding stator teeth of a second stage, wherein the second stage has a second diameter greater than the first diameter, wherein the one or more stages each comprise a rotor and a stator and the outer diameter of each stage is defined by the outer diameter of the stator; and   discharging the drilling fluid. 8. The method of claim 7, further comprising: forcing the drilling fluid through a third set of rotor teeth and corresponding stator teeth of a third stage. 9. The method of claim 7, further comprising: injecting the drilling fluid downhole. 10. The method of claim 7, further comprising: repeating the steps of injecting, forcing, and discharging until a desired drilling fluid rheology is reached. 11. The method of claim 10, further comprising: adding a weighting agent to the drilling fluid. 12. The method of claim 7, further comprising: transferring the drilling fluid to a holding tank.
