Summary
This chapter discusses several techniques for detection and analysis of geopressure in real time. This deals with real-time updates of a predrill pore pressure model during drilling. This is an important phase during which real-time data are acquired, processed, and integrated with the model so that an updated look-ahead and look-around (drill bit) image of geopressure is made.This way, as drilling continues, the cone of uncertainty will reduce. All real-time sensors such as the logging-while-drilling (LWD) tools are at least a hundred or more feet behind the bit. Therefore, calibration must be done in three steps - behind the bit (using all processed logs, including wireline), at the bit (mostly real-time logs), and look-ahead of and around the bit (mostly calibrated seismic model).
