Maximum height of oil column in cap rock
Input(s)
\(P_{a}\): Total Potential energy of accumulation (psi)
\(P_{w}\): Water Potential in Reservoir (psi)
\(G_{o}\): Initial oil pressure gradient in Reservoir rock \(\left(\mathrm{cm}^{2}\right)\)
\(\alpha\): Height Constant (dimensionless)
\(\mathrm{h}\): Depth \((\mathrm{ft})\)
\(P_{c}\): Capillary Pressure (psi)
\(\rho\): Density differential between fluids (ppg)
Output(s)
H: Maximum Height of Oil Column (ft)
Formula(s)
\[
H=\frac{P_{a}-P_{w}+G_{o} * h * \alpha+P_{c}}{\rho-G_{o}}
\]
