Number of sacks of cement required for a given length of plug
Input(s)
\(\mathrm{L}_{\mathrm{p}}\): Plug Length (ft)
\(\mathrm{C}_{\mathrm{c}}\): Casing Capacity \(\left(\mathrm{ft}^{3} / \mathrm{ft}\right)\)
E: Excess Volume (fraction)
Y: Slurry Yield \(\left(\mathrm{ft}^{3} /\right.\) stroke \()\)
Output(s)
\(\mathrm{N}_{\mathrm{s}}\): Sacks of Cement Required (unitless)
Formula(s)
\[
\mathrm{N}_{\mathrm{s}}=\frac{\mathrm{L}_{\mathrm{p}} * \mathrm{C}_{\mathrm{c}} * \mathrm{E}}{\mathrm{Y}}
\]
