%X A careful analysis of the geopressure regime in one hundred wells on the North West Shelf (NWS) is integrated with an analysis of apparent overpressure derived from the regional hiQbe&#x2122; velocity model. The well analysis is a traditional pressure interpretation, considering all available data and all types of overpressure. The hiQbe&#x2122; analysis is based on velocity data, and can therefore detect compaction disequilibrium overpressure. The calibration and integration of these two forms of analysis give new insight into the regional distribution of potentially overpressured rocks in the NWS, and provides a good basis and guidance for well planning.
