COURSE OVERVIEW

This practical and highly-interactive course includes various practical sessions and exercises. Theory learnt will be applied using one of our state-of-the-art simulators.

This course is designed to provide participants with a detailed and up-to-date overview of Prediction of Subsurface Pressures in Drilling Engineering. It covers the importance of predicting subsurface pressures including its types and effects of pressure variations on wellbore stability; the types of formation pressures and their significance; the overburden pressure and stress distribution; the pore pressure prediction techniques and the causes of overpressure and under pressure; the normal, subnormal and overpressure zones; and the well control and kick detection, geological indicators of formation pressure and direct measurement of formation pressures.

Further, the course will also discuss the indirect methods for pressure estimation, well logs for pore pressure estimation and drilling data for pressure prediction; the fracture gradient and breakdown pressure; the methods for estimating fracture gradient and wellbore stability and mud weight optimization; the safe mud weight and pressure margins; the calculation of kick tolerance for well control; and managing narrow pressure windows in HPHT wells.

During this interactive course, participants will learn the real-time pressure monitoring systems, managed pressure drilling (MPD) and its benefits and early kick detection techniques; the characterization of high-pressure high-temperature (HPHT) reservoirs; the well control techniques for abnormal pressure zones; the impact of overpressure on casing and cementing; the MPD techniques for pressure control and underbalanced drilling for overpressured reservoirs; the lost circulation and wellbore strengthening techniques; and the pressure testing and leak-off test interpretation.
