In practice, the displacement pressure is estimated from laboratory measurements. In real rocks, the single pore-throat radius of the equations on page 10–68 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 |
