Guest Speaker: Dr. Mark Tingay

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 reseach and scientific communication, including the AAPG JC Cam Sproule Award, EAGE Lousi 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.

PESA NSW Short course: “Fundamentals of Pore Pressure Prediction and Petroleum Geomechanics”

Date:      Monday 13th & Tuesday 14th March 2017

Course Overview

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. Finally, knowledge of petroleum geomechanics is particularly important in enhancing production in naturally fractured reservoirs and coals, as well as for hydraulic fracture stimulation, and thus is highly valuable in unconventional reservoirs. Knowledge of petroleum geomechanics and pore pressure prediction techniques is particularly important in Australia and SE Asia, which is often characterized by complicated geology, variable and often high-magnitude stress states and anomalous overpressures.

Dr Tingay will present a two-day intensive course on the fundamentals of pore pressure prediction and petroleum geomechanics, 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. The course will then examine the basics of wellbore geomechanics, including stress, strain and rock failure, stress determination for petroleum data, prediction of fracture gradient and wellbore collapse pressures from log data and the application of geomechanics in the oil-patch.
