This volume of gas has been separated from produced water.

This volume of gas has been separated from produced water.

• A. Dry gas
• B. Wet gas
• C. Associated gas
• D. Blue gas

Answer: (D)

The idea is about the gas stream that remains after removing the produced water. Once you separate the water, the gas is typically methane-rich and largely free of condensable liquids, known in industry terms as dry gas. In some training materials this dry, condensate-free gas is labeled as blue gas. So the volume described as separated from produced water fits the blue gas category because it represents the dry, methane-dominated portion rather than a condensate-bearing stream. Wet gas would still carry natural gas liquids, and associated gas refers to gas tied to oil in the reservoir, which isn’t the point of this separation step.
