Abstract

A method of recovering hydrocarbons comprises introducing a suspension comprising nanoparticles to a material and contacting surfaces of the material with the suspension. After introducing the suspension comprising the nanoparticles to the material, the method further includes introducing at least one charged surfactant to the material and removing hydrocarbons from the material. Accordingly, in some embodiments, the nanoparticles may be introduced to the material prior to introduction of the surfactant to the material. Related methods of recovering hydrocarbons from a material are also disclosed.

First claim

What is claimed is:
