This high pore pressure can lead to kick during drilling or other related wellbore operations if not managed cautiously. Moreover, salt or potash in its raw form is plastic in nature with a unique stress...

This will cause in-situ stress re-orientation and possibly reversal and potentially lead to rock deformation and failure by fracture initiation, and/or activation of discontinuities such as joints and bedding planes. The net result is the enhancement...

... with the focal mechanisms provide an estimate of pore pressure at the location of every event, which can be mapped in time and space. We successfully apply joint stress inversion to a Barnett shale hydraulic fracturing dataset and demonstrate pore pressure mapping. Introduction Determination of the stress...

As we would expect, wells with the most permeability, higher pore pressure, effective porosity and lower water saturation have the greatest potential for hydrocarbon production...

... Abstract Effective stress represents the external load carried by the rock itself being a function of confining stresses and pore pressure. Confining stresses can be calculated from elastic rock properties, while effects of pore pressure, requires knowledge of the Biot-Willis coefficient...

... in external and internal forces commonly assume isotropy and a simple stress sensitivity framework where the poroelastic behavior is uniquely controlled by the difference between confining and pore pressure. Such approaches ignore the variable contribution of grain compressibility. Poroelasticity theory...

... Abstract We introduce a physics-based method for explicit pore pressure prediction in naturally fractured shale petroleum reservoirs. Failing to account for the actual cause of overpressure leads to underestimation of the pore pressure at depth. This is particularly important in shales...

... Abstract Pore pressure depletion, in response to production, impacts the economics of child wells by reducing contact with virgin reservoir. In some cases, depletion increases the likelihood of sustaining damaging frac hits in the parent well by creating a pressure sink that directs fracture...
