Equivalent water saturation in burned zone in-situ combustion by Nelson

Input(s)

$\mathrm{x}$: Equivalent $\mathrm{H} / \mathrm{C}$ Molar Ratio (ratio)

$\emptyset$: Volume of Air Required to Burn through a Unit Volume of Reservoir (Mscf/ $\mathrm{ft}^{3}$ )

$a_{r}$: Volume Required to Burn through Reservoir $\left(\mathrm{ft}^{3}\right)$

m: Ratio of Carbon Monoxide to Carbon Emissions (fraction)

Output(s)

$S_{w F}$: Water Saturation Resulting from Combustion (fraction)

Formula(s)

$$ \mathrm{S}_{\mathrm{wF}}=\frac{0.319 * \mathrm{x} * \mathrm{a}_{\mathrm{r}}}{\emptyset *(4-2 * \mathrm{~m}+\mathrm{x})} $$
