Pore pressure prediction and lateral stress determination for an exploration well, a case studies

Pore pressures trend are different in certain areas. This is due to the geological factor that took place over the geological time. Most of the hydrocarbon reservoir are lies beneath the thick sedimentary shale that are not hydrostatic pressure, instead they are an abnormal pressures especially for...
