Dimensionless storage constant for liquids
Input(s)
C: Storage
B: Formation Volume Factor (Reservoir Volume/Standard Volume)
\(V_{s c}\): Specific Volume at Standard Conditions (cc/g)
\(\varnothing\): Porosity (fraction)
\(h\): Net Formation Thickness (m)
\(c_{t}\): Total System Effective Isothermal Compressibility \(\left(\mathrm{kg} / \mathrm{cm}^{2}\right)^{-1}\)
\(r_{w}\): Well Radius \((\mathrm{m})\)
Output(s)
\(C_{D}\): Dimensionless Storage Constant for Liquids (dimensionless)
Formula(s)
\[
C_{D}=\frac{C B V_{s c}}{2 \pi \varnothing h c_{t} r_{w}^{2}}
\]
