A process for desalting a crude oil comprises (1) injecting steam into the oil to form a steam-injected oil; (2) adding water to the steam-injected oil to form a mixture; (3) introducing the mixture to a desalter; (4) inducing the formation of aqueous phase and oil phase; and (5) separating the oil

A process for desalting a crude oil comprises (1) injecting steam into the oil to form a steam-injected oil; (2) adding water to the steam-injected oil to form a mixture; (3) introducing the mixture to a desalter; (4) inducing the formation of aqueous phase and oil phase; and (5) separating the oil phase from the aqueous phase. Where there are two desalting stages for desalting crude oil, the process can be carried out in either the first stage or second stage, or both stages. The process can also be similarly employed in a multistage desalting process.
