Fundamentals of Pore Pressure Prediction

Course Rationale
The safe drilling of wells requires detailed pre-drill prediction of pore pressures, fracture gradients and potential wellbore instability. Accurate pore pressure and fracture gradient prediction is vital for several aspects of well planning, such as casing and cementing design, as well as the prevention of potentially disastrous kicks, losses and blowouts. Furthermore, wellbore instability and associated events, such as pack-offs and stuck pipe, are regarded as the largest cause of non-productive time in deep-water drilling operations. Thus, wellbore stability, pore pressure and fracture gradient analysis represents a key part in reducing drilling costs and optimizing drilling, both in the planning and operational stages of drilling a well.

Dr Tingay has developed a one-day intensive course on the fundamentals of pore pressure prediction, with a particular focus on examples and applications in Australia and SE Asia. This course will cover the fundamentals of pore pressure measurement, overpressure generation, overpressure analysis, and pore pressure prediction in order to provide attendees with an understanding of the core components of pore pressure prediction in the region.

Course Outline
Day 1: Fundamentals of Overpressure and Pore Pressure Prediction

  • Introduction to pore pressure
    • Definitions of pore pressure and overpressure.
    • Where overpressure is found.
    • Geological expressions of overpressure.
    • General importance of overpressure and pore pressure prediction.
  • Measuring pore pressure
    • Wireline logging measurements.
    • Drilling based measurements.
    • The ‘sand/shale’ dilemma in overpressure analysis.
  • Overpressure Generation Mechanisms
    • Effective stress mechanisms (disequilibrium compaction, tectonic loading).
    • Fluid expansion mechanisms (e.g. kerogen to gas maturation, clay diagenesis).
    • Determining overpressure generation mechanisms
    • Worked examples from Thailand and Brunei
  • Introduction to Pore Pressure Prediction
    • Basic prediction concepts.
    • Common pore pressure prediction methods (e.g. Eaton, Bowers, Equivalent Depth).
    • Log-based pore pressure prediction examples
    • Review of seismic velocities for pre-drill prediction
    • Drilling-based PPP (D-exponent, gases, cuttings analysis, kick detection)
    • Integrating and updating pre-drill and real-time predictions.
    • Importance of post-drilling reflection and review.

Course Presenter Biography
Dr Tingay has over 16 years experience in overpressure analysis, pore pressure prediction and petroleum geomechanics. He graduated with a PhD from the University of Adelaide in 2003 and has since had various roles in academia and Chevron, and is currently an independent consultant. He has conducted over 25 industry-based research and consulting projects on a range of petroleum geomechanics and overpressure issues. Dr Tingay has worked world-wide, but with a primary focus on the Asia-Pacific region, including leading the latest release of the Australian Stress Map, compilation of the first present-day stress map for SE Asia, and overpressure analysis and development of new pore pressure prediction methods in five basins. Dr Tingay’s research track record includes publication of over 65 peer-reviewed papers, giving over 100 presentations to conferences, professional society meetings and companies, and providing over 80 media interviews. He has received over a dozen awards for research and scientific communication, including the AAPG JC Cam Sproule Award, EAGE Louis Cagniard Award, ASEG Early Achievement Award, a prestigious ‘Young Tall Poppy Science Award’ and was runner-up for South Australian Young Scientist of the Year.

Dr Tingay has extensive experience and training in teaching, having given 18 industry courses for companies and professional societies. Furthermore, Dr Tingay has a broad teaching background that includes drilling engineering, petrophysics, wireline logging, structural geology, geophysics, geodynamics, sedimentology, stratigraphy and petroleum geology. Dr Tingay holds a Graduate Certificate in Education (Higher Education) in adult education practices.

Registration at short course includes attendance at PESA luncheon on that day.
