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)

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