Abstract

The commonly used model for fracture pressure determination makes use of the ratio of the horizontal effective stress and the vertical stress as a function of the Poisson's ratio, the latter being inferred from seismic velocities. It has been documented that fracture pressure predicted in such a way deviates systematically from what is derived from LOT data, so the predictions provide an unreliable basis for well planning. In this paper, we analyze the reasons for the deviations and present a new methodology to predict Poisson's ratio and fracture pressure using seismic, well log and laboratory data. Examples confirm the superiority of the new methodology.
