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)
\[
\mathrm{N}_{\mathrm{s}}=\frac{\mathrm{L}_{\mathrm{c}} * \mathrm{C}_{\mathrm{c}}}{\mathrm{Y}}
\]
