Gas cap ratio
Input(s)
G: Initial Gas Cap Volume (SCF)
\(\mathrm{B}_{\mathrm{gi}}\): Initial Gas Formation Volume Factor \((\mathrm{bbl} / \mathrm{SCF})\)
\(\mathrm{N}\): Initial Oil in Place (STB)
\(\mathrm{B}_{\mathrm{oi}}\): Initial Oil Formation Volume Factor (bbl/STB)
Output(s)
m: Gas Cap Ratio (dimensionless)
Formula(s)
\[
\mathrm{m}=\frac{\mathrm{G} * \mathrm{~B}_{\mathrm{gi}}}{\mathrm{N} * \mathrm{~B}_{\mathrm{oi}}}
\]
