Features
- Dissolves after the frac to leave a full bore with no drillout run.
- Ball drop and ball-in-place versions on every size.
- HELISEAL versions use the WellBoss HELISEAL fluid propulsion system, which averages 40% less water for pumpdown.
- Full suggested run-speed and pumpdown tables supplied for every size and casing weight.
- Imperial and metric specification sheets for every size.
Applications
- Plug-and-perf multistage fracturing
- Unconventional gas wells, including HPHT tight gas
- Refracturing inside 4" liners (SoluBoss Refrac)
- Wells where coiled tubing drillout is costly or not possible
