The magnitudes of the tangential and radial stresses acting on a borehole or opening are controlled by The magnitude and orientation of the principal reservoir (far field) stresses, the inclination of the wellbore/perforation cavity stress field with the reservoir stress field...

... derived based on Darcy's law as opposed to the herein followed AD formulation. Mathematical consistency of the derived ATPM solution is verified using the data provided in Table 2 . Setting the magnitude of the macro-fracture pseudopermeability very large ensures the ATPM reduces to a dual porosity...

... Abstract The present work integrates sonic logs, image logs, lab test, leak-off test (LOT), production, and injection data to build the basic geomechanical model in a mature field under peripheral water injection. In the modeling process, in-situ stresses (orientation and magnitude) were...

This paper presents a methodology of incorporating data from the microfracturing test into a comprehensive geomechanical model to determine the direction and magnitudes of in-situ reservoir stresses and other rock...

... of screenouts occur when the magnitude of the MR is equal-to or greater-than 0.5. That is, ∆P4 / ∆P1 ≥ 0.5, while simultaneously the magnitude of the NWB friction is equal-to or greater-than 30 bar (≥ 435 psi). Simultaneous use of the MR and of the NWB friction avoids ambiguities as the MR is a direct...

... field development of tight gas sands is the stress evolution accompanying drawdown and depletion. It is now well established that reservoir pressure changes have an effect on both the stress magnitudes and the stress directions in the sub-surface. Two major consequences of the stress changes...
