... is generally considered a principal stress. Evolution of the maximum and minimum horizontal stresses can be characterized by their respective stress paths, K2 and K1. These stress paths are defined as the variation of effective stress relative to the variation of effective overburden stress, or: '' 2...

... are in the direction perpendicular to the well trajectory, or in other words, the well should be drilled in the direction of the maximum horizontal stress. There are several ways one may try to determine the direction of the initial maximum horizontal stress in reservoir rock: Conceptual restoration of structural...

... Abstract A Mohr-Coulomb failure criterion is applied to estimate fluid pressures that may cause fault reactivation during the depletion of hydrocarbon reservoirs. The estimates incorporate the decline in total minimum horizontal stress that accompanies fluid pressure depletion in hydrocarbon...

... of linear elasticity. One of the principal stresses is vertical stress SV, hence the other two principal stresses are major and minor horizontal stresses, SHmax and Shmin. We consider a borehole of deviation angle , and azimuth (relative to the maximum horizontal stress axis) which runs through...

... at any given porosity. For reservoirs in which the vertical stress is larger than the two horizontal stresses, there is also a potential to induce normal faulting in a depleting reservoir when the change of minimum horizontal stress, ?S h , exceeds a critical fraction of ?P p (the change in formation...
