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)

$$ C_{D}=\frac{C B V_{s c}}{2 \pi \varnothing h c_{t} r_{w}^{2}} $$
