Stroke per minute required for a given annular velocity
Input(s)
AV: Annular Velocity \((\mathrm{ft} / \mathrm{min})\)
AC: Annular Capacity (bbl/ft)
\(\mathrm{q}_{\mathrm{o}}\): Pump Output (bbl/stroke)
Output(s)
SPM: Strokes Per Minute Required (unitless)
Formula(s)
\[
\mathrm{SPM}=\frac{\mathrm{AV} * \mathrm{AC}}{\mathrm{q}_{\mathrm{o}}}
\]
