Paper presented at the SPE/AAPG/SEG Unconventional Resources Technology Conference, June 20–22, 2022
Paper Number: URTEC-3708962-MS
... Abstract The objective of this paper is to quantify both the formation stress depletion and the pore pressure depletion caused by production from existing parent wells in the Eagle Ford using observed field data. When future infill wells are added to the development area, the formation pore...

... was as a result of pore pressure in highly pressurized producible formations below the potash formation. 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...

... 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...

... the impact of completion and frac design on multi-fractured horizontal Wolfcamp B well production and economic performance. 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...

Paper Number: URTEC-2021-5279-MS
... 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...
