Building a Regional Pressure Model: A Case Study From The Browse Basin

In this presentation Toh Shi-Yuan looks at the results of a regional pressure analysis of the offshore areas of the Browse Basin and the southern Vulcan Sub-Basin. We discuss building a regional pressure model to describe shale overpressure due to primary and secondary disequilibrium compaction. The developed geological pressure model displayed a good match against the shale pressure predictions and/or formed the upper bound of the observed shale pressure/drilling data for the majority of the analysed wells across the study area. The model is particularly useful when planning to drill in areas with few offset wells for calibration and this may also form a supplement to pore pressure predictions from seismic velocities away from well control and thereby significantly reduces the risk of encountering un-expected high pressures.
