  • Method for estimating pore fluid pressure
    Patent number: 5200929
    Abstract: A method for estimating pore fluid pressure in a subterranean formation is disclosed for use in drilling wells. A pair of velocity-effective stress relations are used to compute pore fluid pressure from velocity data. One relation applies when the current effective stress is the highest ever experienced by the subterranean formation. The second relation accounts for hysteresis effects when the effective stress has been reduced. Pore fluid pressure is found by subtracting the computed effective stress from an estimate of the overburden stress.
