... for the wellbore-scale stress analysis. Results indicate that despite their common use, the uniaxial models may return significantly erroneous predictions of the in-situ stress state in depleted reservoirs. In particular, the in-situ stress changes are found to strongly depend on the geological azimuth and radial...
