Formula 2.159
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)
$$ \mathrm{N}_{\mathrm{s}}=\frac{\mathrm{L}_{\mathrm{c}} * \mathrm{C}_{\mathrm{c}}}{\mathrm{Y}} $$
