Formula 4.79
Sand weight needed to refill a hydraulically fractured reservoir volume
Input(s)
$V$: Volume of Unit Area of the Fracture $\left(\mathrm{ft}^{3} / \mathrm{ft}^{2}\right)$
Ø: Porosity (fraction)
$\rho_{\text {sand }}$ : Density of the Sand $\left(\mathrm{lb} / \mathrm{ft}^{3}\right)$
Output(s)
$S$: Sand Weight needed to Refill the Hydraulically Fractured Reservoir Volume $\left(\mathrm{lb} / \mathrm{ft}^{2}\right)$
Formula(s)
$$ S=V \cdot(1-\varnothing) \cdot \rho_{\text {sand }} $$
