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)

$$ \mathrm{N}_{\mathrm{p}}=7758 * \emptyset *\left(\frac{\mathrm{h}_{\mathrm{n}}}{\mathrm{h}_{\mathrm{t}}}\right) *\left(\mathrm{~S}_{\mathrm{oi}}-\mathrm{S}_{\mathrm{or}}\right) * \mathrm{E}_{\mathrm{c}} * \mathrm{~V}_{\mathrm{s}} $$
