Abstract
Oil-based mud cuttings are cleaned of drilling fluid and mud additives. After sorting and rinsing the cuttings with diesel, the cuttings are put in a syringe, which is repeatedly filled and emptied of diesel. The cuttings are then washed in the syringe with pentane. The cuttings are then crushed and exposed to a solvent a second time. Instead of placing the cuttings in the syringe, alternatively, the cuttings remain on a sieve and the syringe is used to spray the cuttings with diesel, followed by pentane.
