  • Patent number: 6550552
    Abstract: Oil drill cuttings, containing an oil-based mud, may be treated by mixing the cuttings with an organic solvent. The oil drill cuttings are then separated from the organic solvent and extracted oil. The organic solvent is then separated from the oil, and mixed with the extracted oil drill cuttings to extract additional oil therefrom. The oil drill cuttings are again separated from the organic solvent and oil, the oil separated from the solvent, and recombined with the oil from the first extraction step. The oil base and other mud components are recycled, depending on the treatment procedure, for subsequent use in drilling.
