Abstract
An oil recovery process includes recovering an oil-water mixture from an oil-bearing formation and separating the produced water from the oil-water mixture. The produced water includes dissolved gases and the method includes heating and pressurizing the produced water. After the produced water is heated and pressurized, it is flash vaporized through a lesser pressure which produces a vapor and residual produced water. The flash vaporization of the produced water evaporates dissolved gases and the dissolved gases are vented away with the vapor.
