Pore pressure prediction has been a vital concern to the oil and gas industry for many decades. Most petroleum provinces exhibit overpressures, and as the industry explores for deeper targets, encountering high overpressures is becoming more common. As deeper and more complex geology is drilled, the technical difficulties in predicting and safely drilling through overpressures have become more prominent and challenging.
Divided into six chapters, this Getting Started volume covers:
the origin and mechanisms for generating overpressure
obtaining pressure measurements and other indications of formation pressure
using velocity and seismic data to predict pore pressures
basin modeling for predicting pore pressure development
how well logging measurements, shale sonic travel time, and resistivity and drilling data are used to monitor wells for pore pressure during drilling operations
three published, commonly cited case studies that integrate the common techniques used in pore pressure prediction
