In an oil reservoir, the gas dissolved in the oil under natural conditions is called?

• A. Nonassociated Gas
• B. Gas Condensate
• C. Wet Gas
• D. Associated Gas

Answer: (D)

Gas dissolved in oil within an oil reservoir is categorized as associated gas because it originates with and is produced together with the oil. In reservoir conditions, some natural gas is soluble in crude oil; as the well produces and pressure drops, this dissolved gas separates and comes up with the oil stream. The gas is still considered associated with the oil since it was part of the same hydrocarbon system and is produced from the same reservoir. This distinguishes it from nonassociated gas, which comes from reservoirs that do not contain oil, and from gas condensate or wet gas, which describe gas processing characteristics rather than the gas’s origin in the oil-bearing formation.
