Total water production from in-situ combustion - Nelson and McNeil
Input(s)
\(V_{r}\): Volume of Reservoir burnt \(\left(\mathrm{ft}^{3}\right)\)
\(\phi\): Porosity (fraction)
\(S_{i}\): Initial Water Saturation (fraction)
\(S_{f}\): Water Saturation after burning Reservoir (fraction)
Output(s)
\(W_{p}\): Cumulative Water production (bbl)
Formula(s)
\[
\mathrm{W}_{\mathrm{p}}=7758 * \mathrm{~V}_{\mathrm{r}} * \varnothing *\left(\mathrm{~S}_{\mathrm{i}}-\mathrm{S}_{\mathrm{f}}\right)
\]
