Fluid volume required to spot a plug

Input(s)

Lt\mathrm{L}_{\mathrm{t}}: Length of Tubing or Pipe (ft)(\mathrm{ft})

Lp\mathrm{L}_{\mathrm{p}}: Length of Plug (ft)(\mathrm{ft})

Ct\mathrm{C}_{\mathrm{t}}: Tubing or Pipe Capacity (bbl/ft)(\mathrm{bbl} / \mathrm{ft})

Vs\mathrm{V}_{\mathrm{s}}: Spacer Volume behind Slurry (bbl)

Output(s)

V: Fluid Volume Required (bbl)

Formula(s)

V=((LtLp)Ct)Vs\mathrm{V}=\left(\left(\mathrm{L}_{\mathrm{t}}-\mathrm{L}_{\mathrm{p}}\right) * \mathrm{C}_{\mathrm{t}}\right)-\mathrm{V}_{\mathrm{s}}
