Diffusion through cleat spacing in coalbed methane reservoirs
Input(s)
s: Coal Cleat Spacing (ft)
\(\mathrm{t}\): Desorption Time from the Canister Test (day)
Output(s)
D: Diffusion Coefficient \(\left(\mathrm{ft}^{2} / \mathrm{day}\right)\)
Formula(s)
\[
\mathrm{D}=\frac{\mathrm{s}^{2}}{8 * \pi * \mathrm{t}}
\]
