Total oil production from in-situ combustion - Nelson and McNeil
Input(s)
\(V_{r}\): Volume of reservoir Burned \(\left(\mathrm{ft}^{3}\right)\)
\(S_{i}\): Initial oil Saturation (fraction)
\(S_{f}\): Oil Saturation left after Combustion (fraction)
\(V_{p}\): Pattern Volume \(\left(\mathrm{ft}^{3}\right)\)
\(\emptyset\): Porosity (fraction)
Output(s)
\(N_{p}\): Cumulative Oil production (bbl)
Formula(s)
\[
\mathrm{N}_{\mathrm{p}}=7758 * \emptyset *\left(\mathrm{~V}_{\mathrm{r}} *\left(\mathrm{~S}_{\mathrm{i}}-\mathrm{S}_{\mathrm{f}}\right)+0.4 *\left(\mathrm{~V}_{\mathrm{p}}-\mathrm{V}_{\mathrm{r}}\right) * \mathrm{~S}_{\mathrm{i}}\right)
\]
