.... In horizontal rock samples with bedding planes (BP), lower horizontal tension at failure typically occurs in a BTS test when loading the sample parallel to bedding (PLTB) versus perpendicular to bedding (PDTB). This is because bedding activation failure mode dominates in PLTB versus typical central fracture...

... pressure, several FEM simulations were run using different wellbore orientations. As expected, results show that the best orientation is parallel to the minimum horizontal stress, because in this case hydraulic fractures grow perpendicular to the wellbore.

One consequence of this approximation in the Mohr-Coulomb model is that when material fails in tension during cyclic...
