Abstract
The present invention is directed to a method for determining the stress at the borehole boundary at a selected location within a borehole. The present invention comprises a method for determining the stress employing a plurality of mechanical properties of the formation, e.g., Poisson's Ratio, the rock strength properties and the elastic modulus, together with the measured deformation of the deformed borehole at the selected location. The method comprises measuring at the selected location a plurality of parameters indicative of the formation at that location and from which a plurality of mechanical properties of the formation, e.g., the rock strength properties, the elastic modulus and Poisson's Ratio are determinable, calipering the borehole at the selected location to determine the deformation of the deformed borehole and determining the stress at the borehole boundary at the selected location employing the information obtained by measuring and calipering.
