Abstract: Precipitated particles may be formed under conditions that provide a particle morphology suitable for conveying a desired set of properties to a wellbore circulation fluid. Methods for using precipitated particles in a wellbore may comprise: selecting precipitation conditions for producing precipitated particles that are substantially non-spherical in shape, are about 1 micron or under in size, or any combination thereof; forming the precipitated particles from a reaction mixture under the precipitation conditions without using a polymeric dispersant; and introducing a wellbore circulation fluid comprising a plurality of the precipitated particles into a wellbore penetrating a subterranean formation. The precipitation conditions may include one or more of modulating various reaction conditions, applying an electric field to the reaction mixture, or including a carbohydrate-based material in the reaction mixture.

Abstract: Embodiments disclosed herein relate to a method including feeding an invert emulsion wellbore fluid, or a previously used invert emulsion wellbore fluid, into a mixing unit; adding an additive to the mixing unit; delivering the invert emulsion wellbore fluid and the additive to one or more stages of the mixing unit, the mixing unit having a shear rate ranging from about 10,000 s-1 to about 100,000 s-1. The invert emulsion wellbore fluid includes a non-oleaginous fluid being the discontinuous internal aqueous phase of the wellbore fluid, and an oleaginous fluid being the continuous external phase of the wellbore fluid.

Abstract: A system for injecting a fluid into a formation including a fluid, and at least one injection pump configured to receive the fluid, the at least one pump including a centrifugal pump having at least two stages configured to increase the pressure of the received fluid is disclosed. The system further includes a drive device coupled to the injection pump. A method of injecting a fluid downhole including providing a fluid to an injection pump, the injection pump including a centrifugal pump having at least two stages, pumping the fluid through the at least two stages of the centrifugal pump, thereby increasing the pressure of the fluid, and injecting the fluid from the injection pump into a wellbore is also disclosed.
