Total oil production from wet in-situ combustion - Nelson and McNeil
Input(s)
\(V_{r}\): Volume of Burnt reservoir \(\left(\mathrm{ft}^{3}\right)\)
\(\emptyset\): Porosity (fraction)
\(S_{i}\): Initial Oil Saturation (fraction)
\(S_{f}\): Oil Saturation post fire flood (fraction)
\(V_{s}\): Volume of Steam \(\left(\mathrm{ft}^{3}\right)\)
\(S_{r}\): Residual oil Saturation (fraction)
\(h_{n}\): Net thickness of Reservoir ( \(\mathrm{ft}\) )
\(h_{t}\): Total thickness of reservoir \((\mathrm{ft})\)
E: Efficiency of Fire Flood (fraction)
Output(s)
\(N_{p}\): Cumulative oil production (bbl)
Formula(s)
\[
\mathrm{N}_{\mathrm{p}}=\left(\frac{7758 * \emptyset * \mathrm{E} * \mathrm{~h}_{\mathrm{n}}}{\mathrm{h}_{\mathrm{t}}}\right) *\left(\mathrm{~V}_{\mathrm{r}} *\left(\mathrm{~S}_{\mathrm{i}}-\mathrm{S}_{\mathrm{f}}\right)+\mathrm{V}_{\mathrm{s}} *\left(\mathrm{~S}_{\mathrm{i}}-\mathrm{S}_{\mathrm{r}}\right)\right)
\]
