Excessive wellbore breakouts, wellbore washouts (uncontrolled borehole enlargement) frequent tight pull & held up, undesirable log quality in drilled wells, necessitates understanding the subsurface behaviour of the wells & basic cause of the problems. Rocks at depths are subjected to stresses resulting mainly from the weight of the overlying strata and the locked in stresses of tectonic origin. In-situ stress magnitudes and orientations play a very significant role in understanding the subsurface behaviour during drilling, reservoir modelling, well stimulation and production optimization.
