ABSTRACT:
A method for the disposal of oil field wastes contaminated with naturally occurring radioactive materials (NORM). The method includes the steps of: drilling a pair of wells which intersect in a salt formation, providing a slurry containing NORM wastes and a carrier liquid, injecting the slurry through one of the wells into the salt formation wherein the NORM wastes settle, and removing the carrier liquid from the other one of the wells. One carrier liquid, fresh water, dissolves the salt formation to form and enlarge a cavern for receiving the NORM wastes. The quantities of carrier liquid removed from the salt formation are disposed of by injection into permeable formation remote from the salt formation.
