Dimensionless injection rate of air for in-situ combustion
Input(s)
\(i_{a}\): Injection Rate \(\left(\mathrm{ft}^{3} / \mathrm{d}\right)\)
L: Length Between Injector and Producer in Pattern \((\mathrm{ft})\)
\(\mathrm{h}\): Formation Thickness \((\mathrm{ft})\)
\(u_{\text {min }}\): Minimum Air Flux \((\mathrm{ft} / \mathrm{d})\)
Output(s)
\(i_{D}\): Dimensionless Air Injection Rate (dimensionless)
Formula(s)
\[
\mathrm{i}_{\mathrm{D}}=\frac{\mathrm{i}_{\mathrm{a}}}{\mathrm{L} * \mathrm{~h} * \mathrm{u}_{\min }}
\]
