ABSTRACT:
A process for cleaning oil-contaminated well bore fluids, and particulate solids. An oil-contaminated well bore fluid, or particulate solids, or both, is admixed with an aqueous polymeric solution and diatomaceous earth, and the admixture filtered to free the oil-contaminated well bore fluid, or solids, of oil which is separated therefrom. The oil-decontaminated well bore fluid is thereby rendered suitable for reuse, and residual solids useful for reblending with the original well bore fluid, or rendered environmentally acceptable for discharge.
