ENHANCED FILTRATION CONTROL PACKAGES, WELLBORE SERVICING FLUIDS UTILIZING THE SAME, AND METHODS OF MAINTAINING THE STRUCTURE OF A WELLBORE

摘要

A wellbore servicing fluid comprises an aqueous base fluid, one or more alkali metal or alkali earth metal salts, at least one viscosifier, and a filtration control package. The filtration control package may comprise a carboxylic acid and a polyethylene glycol. The carboxylic acid may have from 8 to 20 carbon atoms. The polyethylene glycol may have a mass average molar mass (M_w) of less than or equal to 1500 daltons.
