Gas condensate, also known as retrograde condensate, is a type of natural gas reservoir; which term matches this?

• A. Wet Gas
• B. Gas Condensate (Retrograde Condensate)
• C. Dry Gas
• D. Natural Gas

Answer: (B)

Gas condensate reservoirs involve retrograde condensation: as reservoir pressure drops below the dew point, heavier hydrocarbons condense out of the gas to form a liquid called condensate while the gas remains in the reservoir. The term that matches this scenario is Gas Condensate (Retrograde Condensate) because it specifies a natural gas reservoir that produces condensate due to this retrograde condensation behavior. The other options don’t fit as well: wet gas refers to gas with condensable hydrocarbons still in the gas phase at surface, dry gas implies little or no condensable liquid, and natural gas is a broad category not naming the condensate-producing reservoir type.
