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