Fluid volume required to spot a plug
Input(s)
\(\mathrm{L}_{\mathrm{t}}\): Length of Tubing or Pipe \((\mathrm{ft})\)
\(\mathrm{L}_{\mathrm{p}}\): Length of Plug \((\mathrm{ft})\)
\(\mathrm{C}_{\mathrm{t}}\): Tubing or Pipe Capacity \((\mathrm{bbl} / \mathrm{ft})\)
\(\mathrm{V}_{\mathrm{s}}\): Spacer Volume behind Slurry (bbl)
Output(s)
V: Fluid Volume Required (bbl)
Formula(s)
\[
\mathrm{V}=\left(\left(\mathrm{L}_{\mathrm{t}}-\mathrm{L}_{\mathrm{p}}\right) * \mathrm{C}_{\mathrm{t}}\right)-\mathrm{V}_{\mathrm{s}}
\]
