Water influx - Pot aquifer model
Input(s)
\(c_{t}\): Aquifer Total Compressibility \((1 / \mathrm{psi})\)
\(W_{i}\): Initial Volume of Water in Aquifer (bbl)
\(P_{i}\): Initial Reservoir Pressure (psi)
P: Current Reservoir Pressure (Pressure at Oil-Water Contact) (psi)
Output(s)
\(W_{e}\): Cumulative Water Influx (bbl)
Formula(s)
\[
W_{e}=c_{t} * W_{i} *\left(P_{i}-P\right)
\]
