Input(s)

$M_{f}$: Volumetric Heat Capacity of the Injected Hot Fluid (BTU/ft ${ }^{3}$ F)

$M_{r}$: Volumetric Heat Capacity of the Reservoir $\left(\mathrm{BTU} / \mathrm{ft}^{3} \mathrm{~F}\right)$

$h_{t}$: Height (ft)

$\mathrm{i}$: Injection Rate $\left(\mathrm{ft}^{3} / \mathrm{d}\right)$

$\alpha_{s}$: Thermal Diffusivity to Overburden $\left(\mathrm{ft}^{2} / \mathrm{d}\right)$

$M_{s}$: Volumetric Heat Capacity of Steam $\left(\mathrm{BTU} / \mathrm{ft}^{3} \mathrm{~F}\right)$

L: Length (ft)

Output(s)
