ABSTRACT:
Three phase separator systems for separating mixtures downhole are provided that utilize fluid isolation devices or packers to allow sections of casing to separate water, oil, and gas through gravity separation. By utilizing two or more vertical sections of a downhole casing, gravity separation of multiple phases may be accomplished. For example, one vertical section of casing may be used to allow the gravity separation of a liquid mixture and a gas therein while a second vertical section of casing may be used to separate the liquid mixture into a water phase and an oil phase. Numerous other components such as pumps, piping, and valves may form part of the separation system depending on the particular embodiment.
