How do you calculate Bottoms Up Stroke?
“Bottoms Up” Strokes = Annular Volume bbls / Pump Output in bbls-stk. The first thing we must to do in order to calculate “Bottoms Up” or Bit to Surface” strokes is to find the Annular Volume. Annular Volume bbls = (Dh^2 – OD^2) / 1029.4 x Length in feet, where Dh is the hole diameter.
