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)

$$ H=\frac{P_{a}-P_{w}+G_{o} * h * \alpha+P_{c}}{\rho-G_{o}} $$
