In practice, the displacement pressure (Pd) 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 |
