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)

$$ \mathrm{m}=\frac{\mathrm{G} * \mathrm{~B}_{\mathrm{gi}}}{\mathrm{N} * \mathrm{~B}_{\mathrm{oi}}} $$
