Experimental results indicate that supercriticalextraction will reduce the oil-based mudcontamination of drill cuttings to a level that will allow offshoredisposal. Pilot plant experimentswere conducted using HFC 134a and propane as the extractive solvents.A commercial processdesign and cost estimate was prepared. The estimate indicates thatthe supercritical extractiontechnology is very competitive with current cuttings' disposaltechnologies. The process offersthe advantage of allowing the continued use of oil-based mud inenvironmentally sensitiveareas: a major benefit for drilling operations.
