Displacement pressure estimation

In practice, the displacement pressure (P_d) is estimated from laboratory measurements. In real rocks, the single pore-throat radius of the equations in Hydrocarbon column: calculation of maximum height is replaced by a complex pore-throat size distribution.

Estimating techniques

The following table lists techniques commonly used to estimate the displacement pressure of a top seal.

Technique	Needed for the technique
Mercury injection measurements	Cores or cuttings
Log analysis	Logs and database of laboratory measurements
Sedimentary facies	Facies maps and database of laboratory measurements
Pore-size distribution	Thin sections, cores, or cuttings
