Abstract

See full text

The present invention addresses to a method of cleaning rock samples from oil systems, based on the use of a nanofluid, which is capable of considerably accelerating the process. The developed method associates the potential of oil solubilization by the nanofluid under the temporary action of an ultrasound system, being faster and more efficient than the method traditionally used by distillation, then described in the State of the Art. The used procedure reduces the time required for the removal of oil and salt, a critical step in the characterization process of rock samples, normally from 120 to 365 days, to 3 to 7 days, using a low toxicity aqueous-based nanofluid, which does not change the properties of the rocks.
