Geopressure describes abnormally high pressure in subsurface formations; which option lists geopressure at the end?

• A. Overpressure
• B. Underpressure
• C. Pressure gradient
• D. Geopressure

Answer: (D)

Abnormal subsurface pressure terminology is being tested. Geopressure is the term used for abnormally high pressures in subsurface formations. Among the options, the one that literally uses the word geopressure is the correct pick. Overpressure and underpressure describe whether pressure is above or below hydrostatic, not the specific term for the condition. A pressure gradient is about how pressure changes with depth, not labeling the formation pressure itself. Since the question points to geopressure, the option that is the word geopressure is the best answer.
