Abstract
Useful information reflecting unknown attributes of subsurface oil, gas, and water systems can be gained by constructing and interpreting scenarios from simple graphical plots of formation pressure against the depths (or elevation) at which they are measured. There are essentially three exploration problem areas in which such PāD plots are applied: the first concerns the prediction of pay thickness (i.e., placing oil-water, gas-water, and gas-oil interfaces); the second concerns subsurface correlation and the prediction of prospective reservoir trends; the third involves the recognition of subsurface barriers and the definition of geologic pressure systems and placement of boundaries with respect to over- and underpressuring.
