  • Method for overpressure detection from compressional-and- shear-wave data
    Patent number: 6374186
    Abstract: The present invention includes a method for overpressure detection and pore pressure change monitoring in subsurface gas, liquid hydrocarbon, or water reservoirs from compressional- and shear-wave measurement data. As part of this method, one or more Poisson's ratios are determined from field-based measurement data and are then compared against known Poisson's ratio values representative of the particular subsurface formation type. By applying a Poisson's ratio—pore pressure criterion that is appropriate for that type of formation, an overpressure in the formation is identified.
