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