Downhole Technology provides detailed procedures for drilling out Boss Hog plugs upon request. On-site instruction is also available.


  • Communicate with frac crew about any unusual conditions.
  • Calculate volumes of tubing and casing annulus for timing of gel sweeps and returns.
  • Well-designed gel sweeps can minimize need for short trips.
  • Use drill bit or mill with 97% to 100% drift. Rock bits may produce smaller cuttings.
  • Downhole Technology recommends 3% KCl with friction reducer for drillout.
  • Pump while tripping into hole.
  • Follow detailed procedures for tagging plugs and preventing motor stalls.
  • After last plug is drilled, sweep with enough volume to fill the lateral.
  • Debris may gather at 70° to 80° inclination. Increase circulation to avoid sticking.
