Abstract
A method and apparatus for estimating a pressure transition zone in a borehole is disclosed. A parameter indicative of formation fluid pressure at a plurality of borehole depths is measured. A global trend of the parameter is determined over a first depth interval and a local trend of the parameter is determined over a second depth interval. A relation is determined between the global trend and the local trend, and the pressure transition zone is determined from the determined relation between the determined global trend and the determined local trend.
