The pore pressure model is continuously updated while drilling incorporating real-time LWD data to optimize the mud weight so drilling can continue with confi dence. Any combination of seismic, wireline, LWD, mud log, reservoir, and geologic input can be used to analyze formation pore pressure. In addition, the Drilling Formation Tester can minimize risk with real-time calibration points for the pore pressure model. Casing point selection can be improved with a better understanding of the formation pressure around the planned casing point.
