METHOD TO REDUCE SALT NECESSARY TO REACH SATURATION OF DRILLING FLUIDS

摘要

The addition of a non-aqueous, non-oleaginous component into an aqueous-based drilling fluid may reduce the amount of salt necessary for the aqueous-based drilling fluid to reach saturation. The amount of the non¬ aqueous, non-oleaginous component within the aqueous-based drilling fluid may range from about 5 vol% to about 95 vol%. The component may be, but is not limited to glycol, glycerin, polyol, alcohol, and combinations thereof. The aqueous-based drilling fluid may then be used for drilling a wellbore into a subterranean reservoir that contains salt and thereby prevent or inhibit the salt from being leached from the subterranean reservoir.
