This course covers fundamentals of Pore Pressure, ranging from basic theoretical review to practical workflows that can be immediately applied in the field. It will present practical tools for understanding, modeling and predicting Pore Pressure, observing the type of lithologies under study. This course describes how to model overburden, fracture and pore pressures, and related in-situ stress field. Mechanisms of geo-pressure generation will be discussed, and how they impact hydrocarbon generation, and more importantly, how to define a safe well planning to mitigate the occurrence of adverse drilling events.
Moreover, I will show the importance and benefit of linking rock physics, geologic processes (diagenesis and burial history) to the computation of effective stress and pore pressure. RockPhysics models result very convenient to use in order to build and extrapolate compaction trend models away from existing wells, taking into account geological changes (mechanical compaction, clay content and depositional environment). Physical trend models combined with available well data can be used to improve models and predictions of pore pressure profiles for a range of lithological facies (shale, clean sand, shally sand) and fluid types (brine, oil and gas).
The course can be adjusted and customized to the needs and interests of the client.
