WebNormal formation pore pressure (hydro-pressure): This is when the formation pore pressure equals the hydrostatic pressure of an entire column of formation water. Normal pore pressure is usually of the order of 0.465 psi/ft. Abnormal formation pore pressure (geo-pressure): This exists in regions with no direct fluid flow to the adjacent regions.
