See full text

A wellbore servicing fluid comprises an aqueous base fluid, one or more alkali metal or alkali earth metal salts, at least one visocisifier, and a filtration control package. The filtration control package may comprise a carboxylic acid and an ethoxylated alcohol compound. Alternatively, the filtration control package may comprise a polyethylene glycol. The carboxylic acid may have from 8 to 20 carbon atoms. The ethoxylated alcohol compound may have a general formula R—(OCH2CH2)x—OH, where R is a hydrocarbon having from 10 to 16 atoms and x is an integer from 6 to 9. The ethoxylated alcohol compound may have a hydrophilic-lipophilic balance of from 8.0 to 16.0. The polyethylene glycol may have a mass average molar mass (Mw) of less than or equal to 1500 daltons.
