# Effective porosity

## Input(s)

$$V_{P_{e}}$$: Effective Pore Volume $$\left(\mathrm{cm}^{3}\right)$$

$$V_{b}$$: Bulk Volume $$\left(\mathrm{cm}^{3}\right)$$

$$V_{o}$$: Total Oil Volume in Interconnected Pores $$\left(\mathrm{cm}^{3}\right)$$

$$V_{g}$$: Total Gas Volume in Interconnected Pores $$\left(\mathrm{cm}^{3}\right)$$

$$V_{w}$$: Total Water Volume in Interconnected Pores $$\left(\mathrm{cm}^{3}\right)$$

## Output(s)

$$\varnothing_{\text {eff: }} \quad$$ Effective Porosity (fraction)

## Formula(s)

$\begin{gathered} \mathrm{V}_{\mathrm{P}_{\mathrm{e}}}=\mathrm{V}_{\mathrm{o}}+\mathrm{V}_{\mathrm{g}}+\mathrm{V}_{\mathrm{w}} \\ \varnothing_{\mathrm{eff}}=\frac{\mathrm{V}_{\mathrm{P}_{\mathrm{e}}}}{\mathrm{V}_{\mathrm{b}}} \end{gathered}$
