    摘要: 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.

    摘要: Process for recovering and moving highly viscous petroleum products, by the use of aqueous dispersions in the presence of sulphonate dispersers prepared:a) by increasing the molecular weight of steam cracking fuel oil by its oligomerization in the presence of a catalyst selected from BF.sub.3 and complexes thereof with strong acids;b) sulphonating the compound obtained from step (a) by reaction with a sulphonating agent, preferably SO.sub.3 ;c) neutralizing the sulphonate obtained from step (b) by treatment with hydroxides selected from the hydroxides of alkaline or earth alkaline metals or ammonium.
