What vessel is used to separate gas, oil, and water after the mixture is produced from the well?

• A. Treater
• B. Distiller
• C. Demister
• D. Separator

Answer: (D)

A separator is used to split the produced stream into distinct natural phases. After the well, the mixture is a multiphase flow, and the separator uses gravity and vessel design to separate it into gas, oil, and water. Gas, being the lightest, rises to the top; oil forms the middle layer; and produced water settles at the bottom. The gas is handled for processing or sales, the oil is routed for storage or further treatment, and the water is drained off. Other equipment serves different roles: a treater handles cleaning and conditioning the oil after separation (removing water and impurities), a demister removes fine liquid droplets from gas, and a distiller is used in refining to separate components by boiling point rather than at the wellhead.
