BOOST CEMENT SLURRY INTEGRITY
Dual wiper plugs substantially increase cement slurry integrity by providing a barrier on each end of the cement slurry while the cement is pumped through the casing. Two drill pipe darts are incorporated to provide a protective barrier for the cement in the workstring while wiping the inside of the workstring. The darts then launch the appropriate casing wiper plug.
Innovative Features
- Barrier protects cement slurry, lead and follow
- Indication of when lower plug hits landing collar and circulates
- Mostly composite material provides reliability, effective drill-out
- Reduced elastomer on wipers improves drill-out
- Latch-down nose holds differential pressure from below
