ABSTRACT:
Used drilling mud, and other high solids oilfield waste which has been contaminated with hydrocarbons, is pumped downhole into a salt cavity where the mud and hydrocarbons separate with the mud gravitating to the bottom of the cavity and the hydrocarbons rising toward the surface of the ground. Brine separates the accumulated hydrocarbons from the residual mud. The brine or the hydrocarbons is selectively removed for sales while additional water or contaminated mud is added to the system as may be required. The salt cavity preferably is located in a geographical area wherein anhydride ledges are formed therewithin upon formation of the cavity. The resultant ledges form baffle plates that coalesces the separated particles of oil and enhance formation of the separated hydrocarbon.
