Estimation of average reservoir pressure - MDH method
Input(s)
\(\mathrm{p}_{\mathrm{ws}}\): Shut-In Pressure \((\mathrm{psi})\)
pDMDH: MDH Pressure (dimensionless)
m: Semi-log Straight Line of the MDH Plot (psi/cycle)
Output(s)
\(\mathrm{P}_{\mathrm{r}}\): Average Reservoir Pressure (psi)
Formula(s)
\[
\mathrm{P}_{\mathrm{r}}=\mathrm{p}_{\mathrm{ws}}+\mathrm{m} * \frac{\mathrm{p}_{\mathrm{DMDH}}}{1.1513}
\]
