1. A computer-implemented method of estimating mechanical properties and stresses of material surrounding a borehole, the computer-implemented method comprising:

  • inferring in situ, a static Young'"'"'s modulus and a static Poisson'"'"'s ratio of the material surrounding the borehole;

    generating a geomechanical model of the material using the static elastic property; and

    storing the geomechanical model in a memory of a data processing system.
