Experimental results indicate that supercritical extraction will reduce the oil-based mud contamination of drill cuttings to a level that will allow offshore disposal. Pilot plant experiments were conducted using HFC 134a and propane as the extractive solvents. A commercial process design and cost estimate was prepared. The estimate indicates that the supercritical extraction technology is very competitive with current cuttings’ disposal technologies. The process offers the advantage of allowing the continued use of oil-based mud in environmentally sensitive areas : a major benefit for drilling operations.
