摘要： A water extraction process for separating bitumen from tar sands comprises slurrying tar sands in water, mixing the aqueous slurry with a magnetic substance for a time sufficient to release bitumen from tar sands and to uniformly disperse the magnetic substance with the bitumen, and subjecting the resulting slurry to froth flotation for recovery of a bitumen product and production of sand tails. The magnetic substance may comprise a magnetic surfactant. Alternatively, the magnetic substance comprises a magnetic nanoparticle together with a frother having the characteristics of methyl-isobutyl-carbinol and can be mixed with the aqueous slurry by attrition scrubbing or by flotation cell mixing. The magnetic substance may be recovered for further reuse by applying a magnetic or electromagnetic field to the tailings. The process may suitably applied in both so-called hot water extraction processes as well in an “ambient” temperature (from about freezing to 35° C.) process.

摘要： Carbon quantum dots may be introduced into oil-based downhole fluids, such as drilling fluids, completion fluids, stimulation fluids, remediation fluids, and combinations thereof, or into distillate fuels, to increase their electrical conductivity and improve or maintain their performance in oil production and refining operations, in both low and high shear conditions.
