Cumulative oil production - Undersaturated oil reservoirs

Input(s)

$N$: Initial Oil-in Place (STB)

$c_{e}$: Effective Compressibility (1/psi)

$B_{o}$: Oil Formation Volume Factor at the Assumed Reservoir Pressure (bbl/STB)

$B_{o i}$: Oil Formation Volume Factor at Initial Reservoir Pressure (bbl/STB)

$\Delta P$: Pressure Differential (psi)

Output(s)

$N_{p}$: Cumulative Oil Production (STB)

Formula(s)

$$ N_{p}=N * c_{e} *\left(\frac{B_{o}}{B_{o i}}\right) * \Delta P $$
