Estimating performance prediction of steam-drive reservoirs (cumulative oil produced)
Input(s)
\(\emptyset\): Porosity (fraction)
\(h_{n}\): Net Thickness (ft)
\(h_{t}\): Gross Thickness (ft)
\(S_{o i}\): Initial Oil Saturation (fraction)
\(S_{o r}\): Residual Oil Saturation (fraction)
\(E_{c}\): Capture Efficiency (fraction)
\(V_{s}\): Volume of Steam in Reservoir (ac ft)
Output(s)
\(N_{p}\): Cumulative Oil Produced (BBL)
Formula(s)
\[
\mathrm{N}_{\mathrm{p}}=7758 * \emptyset *\left(\frac{\mathrm{h}_{\mathrm{n}}}{\mathrm{h}_{\mathrm{t}}}\right) *\left(\mathrm{~S}_{\mathrm{oi}}-\mathrm{S}_{\mathrm{or}}\right) * \mathrm{E}_{\mathrm{c}} * \mathrm{~V}_{\mathrm{s}}
\]
