Relative permeability

Input(s)

$q_{o}$: Oil Flow Rate $\left(\mathrm{cm}^{3} / \mathrm{s}\right)$

$q_{w}$: Water Flow Rate $\left(\mathrm{cm}^{3} / \mathrm{s}\right)$

$q_{T}$: Total Flow Rate $\left(\mathrm{cm}^{3} / \mathrm{s}\right)$

$k_{o}$: Effective Permeability to Oil (mD)

$k_{w}$: Effective Permeability to Water (mD)

$k$: Absolute Permeability (mD)

$\mu_{o}$: Viscosity of Oil Phase $(\mathrm{cP})$

$\mu_{w}$: Viscosity of Water Phase $(\mathrm{cP})$

$P$: Pressure value that read from Pressure Gauge (Atm)

L: Plug Length $(\mathrm{cm})$

A: Open-Flow Area of the Plug $\left(\mathrm{cm}^{2}\right)$

Output(s)
