A new set of equations helps estimate formation fluid pressures and minimum fracture pressures in liquid-filled, overpressured, soft rock areas before any wells are drilled in the area. This paper reports on the calculation method which uses reflection seismic data to make the estimates which should be helpful for the initial design of mud weight and casing programs. These equations are suited for soft rock areas containing layers of shale and friable sands, such as those in the Gulf Coast or offshore West Africa. Standard seismic interpretation procedures are used to obtain the data. The equations assume that the stronger reflection signals occur where sand bodies exist and area based on the mechanical behavior of uncemented sand.
