WELLBORE SERVICING FLUIDS AND METHODS OF MAKING AND USING SAME

摘要

A method of servicing a wellbore comprising placing an invert emulsion drilling fluid having an oleaginous continuous phase, a non-oleaginous discontinuous phase, and a fluid loss additive into a wellbore wherein the fluid loss additive comprises a quaternary ammonium compound containing at least one ester linkage. A method of servicing a wellbore comprising introducing a clay-free invert emulsion drilling fluid comprising distearoylethyl dimonium chloride to the wellbore. A wellbore servicing fluid comprising an invert emulsion drilling fluid having an oleaginous continuous phase, a non-oleaginous discontinuous phase, and a fluid loss additive into a wellbore wherein the fluid loss additive comprises an esterquat characterized by Structure A:
