Total pore volume compressibility
Input(s)
\(\mathrm{P}_{\mathrm{i}}\): Initial Pressure (psi)
P: Pressure (psi)
\((\mathrm{PV})_{\mathrm{i}}\): Pore Volume at Initial Reservoir Pressure (bbl)
\((\mathrm{PV})_{\mathrm{p}}\): Pore Volume at Pressure P \((\mathrm{bbl})\)
Output(s)
\(\mathrm{c}_{\mathrm{f}}\): Cumulative Pore Volume (Formation or Rock) Compressibility (1/psi)
Formula(s)
\[
\mathrm{c}_{\mathrm{f}}=\left(\frac{1}{(\mathrm{PV})_{\mathrm{i}}}\right) *\left(\frac{(\mathrm{PV})_{\mathrm{i}}-(\mathrm{PV})_{\mathrm{p}}}{\mathrm{P}_{\mathrm{i}}-\mathrm{P}}\right)
\]
