Oil isothermal compressibility, co(p) | bbl/stb |
\displaystyle c_o(p) = \frac{X}{p \cdot 10^5}, \quad X = с_1 + с_2 \, R_{sb} + c_3 \, T + c_4 \, \gamma_g
+ c_5 \, \gamma_{API} |

where
p | psia | Fluid pressure |
T | °F | Initial formation temperature |
\gamma_{API} | API | Oil API gravity |
\gamma_o | frac | Oil specific gravity |
\gamma_g | frac | Gas specific gravity |
R_{sb} | scf/stb | Gas Solubility at Bubble point pressure |
