Abstract: A method for predicting mechanical properties of a transverse isotropic region of a rock formation traversed by a well bore including running a logging tool in the well bore; the mass percentages of minerals present in the rock formation surrounding the well bore are measured with the logging tool. The density of the minerals present in the rock formation surrounding the well bore is determined. The porosity of the rock formation surrounding the well bore is measured. From the porosity and the measured mass percentages and density of the minerals, all the transverse isotropic elastic coefficients of the rock formation are determined in real time.

Abstract: A test cell and method for stress testing a test specimen including a first platen and a second platen. Each platen having a loading surface, an inclined surface, and a longitudinal axis. The inclined surface being inclined relative to the longitudinal axis at an angle and the inclined surface having a specimen recess formed therein for receiving a portion of the test specimen such that when the inclined surface of the second platen is positioned in a face-to-face relationship with the inclined surface of the first platen, a shear stress is applied to the test specimen when an axial load is applied to the first and second platens. The platens further including fluid ports to subject the test specimen to fluid flow at various pressures and fluid chemistries and ultrasonic transducers to determine acoustic, compressional, and shear wave velocities and in multiple orientations.
