Average compressibility of oil
Input(s)
V: Reference Volume (volume fraction relative to bubble point volume or higher pressure)
\(V_{1}\): Volume Fraction at Higher Pressure (fraction)
\(V_{2}\): Volume Fraction at Lower Pressure (fraction)
\(p_{1}\): Pressure (Relative to \(\left.\mathrm{V}_{1}\right)(\mathrm{psi})\)
\(p_{2}\): Pressure (Relative to \(\mathrm{V}_{2}\) ) (psi)
Output(s)
\(C_{o}\): Average Compressibility of Oil \(\left(\operatorname{psi}^{`}(-1)\right)\)
Formula(s)
\[
\mathrm{C}_{\mathrm{o}}=-\frac{1}{\mathrm{~V}} *\left(\frac{\mathrm{V}_{1}-\mathrm{V}_{2}}{\mathrm{p}_{1}-\mathrm{p}_{2}}\right)
\]
