This program provides the analytical solution to borehole stress concentrations around boreholes drilled at an arbitrary orientation in an anisotropic rock formation. The input parameters include: borehole orientation, far-field stress orientation, borehole fluid pressure, elastic constants and orientation of the rock medium. This code was developed as part of a soon to be published paper "A PROGRAM TO CALCULATE THE STATE OF STRESS IN THE VICINITY OF AN INCLINED BOREHOLE THROUGH AN ANISOTROPIC ROCK FORMATION" in the journal Geophysics. A MATLAB version is also available in the paper..
