... the pore pressure and stresses in the reservoir. 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...

... 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...

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

... 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...

... Abstract Accurate formation pressure (pore pressure) prediction is essential for executing a safe and cost-effective drilling program. Unexpected overpressure is a major cause of drilling hazards, costing the industry billions of dollars, and posing a huge potential risk for damage...
