Webhave been used for determining pore pressure prediction (Cibin et al., 2008). For predrill pore pressure prediction, pore pressure can be obtained from seismic velocities using a velocity-to–pore-pressure transform (Sayers et al., 2002). The seismic velocities have lower resolution for well planning purposes. WebWireline logs & pore pressure evaluation & prediction; Well seismic evaluation; Drilling Parameters. In general, the onset of abnormally pressured formations is associated with an increase in the drillability of the formation. This is a deviation from a general trend of reduced drillability with depth due to compaction, increased stresses, etc ...
