Abstract: Quaternary ammonium compounds and methods of using such compounds to, for example, break oil-in-water emulsion treatment fluids are provided. In some embodiments, such methods include introducing a quaternary ammonium compound into an oil-in-water emulsion treatment fluid that comprises an oleaginous phase and an aqueous phase; and centrifuging at least the portion of the oil-in-water emulsion treatment fluid to separate at least a portion of the oil-in-water emulsion treatment fluid into an oleaginous fluid and an aqueous fluid.

Abstract: A fluid pump includes an inlet plate having an inlet; an outlet plate having an outlet plate outlet passage; an outlet which discharges fluid from the fuel pump; an electric motor having a shaft which rotates about an axis; a pumping element rotationally coupled to the shaft such that rotation of the pumping element by the shaft causes fluid to be pumped from the inlet to the outlet plate outlet passage and through the outlet; and a retention clip. The retention clip includes a central portion, a first leg which extends laterally from one end of the central portion, and a second leg which extends laterally from the other end of the central portion. The inlet plate includes an inlet plate slot within which the first leg is located and the outlet plate includes an outlet plate slot within which the second leg is located.

Abstract: A method of drilling in a subterranean formation is disclosed. The method may include providing a direct emulsion drilling fluid comprising an aqueous-based fluid, an oil, and a poly-quaternary ammonium chloride emulsifier; circulating the direct emulsion drilling fluid from the surface, through a wellbore, and back to the surface; and extending the wellbore in the subterranean formation while circulating the direct emulsion drilling fluid.

Abstract: Methods for using treatment fluids and additives that include xanthan gum and attapulgite.
