Number of sacks of tail cement required for casing

Input(s)

$\mathrm{L}_{\mathrm{c}}$: Distance between Float Collar and Shoe $(\mathrm{ft})$

$\mathrm{C}_{\mathrm{c}}$: Casing Capacity $\left(\mathrm{ft}^{3} / \mathrm{ft}\right)$

Y: Slurry Yield of Tail Cement $\left(\mathrm{ft}^{3} /\right.$ stroke $)$

Output(s)

$\mathrm{N}_{\mathrm{s}}$: Sacks Required by Casing (unitless)

Formula(s)

$$ \mathrm{N}_{\mathrm{s}}=\frac{\mathrm{L}_{\mathrm{c}} * \mathrm{C}_{\mathrm{c}}}{\mathrm{Y}} $$
