Abstract
A method of inhibiting the deposition of paraffin wax, asphaltene, or mixtures thereof in a crude oil contaminated with paraffin wax, asphaltene, or mixtures thereof and susceptible to such depositions comprising the step of incorporating into said crude oil an effective deposition inhibiting amount of an oil soluble organic compound having at least one oleophobic and hydrophobic fluoroaliphatic group, and antideposition stabilized crude oil compositions containing said compound, are disclosed.
