The Single Wiper Plug (SWP) System substantially increases cement integrity by preventing contamination of the cement slurry while it is pumped through the drill pipe and casing. The system features a drill pipe dart that provides a mechanical barrier behind the cement in the drill pipe, then launches the casing wiper plug, isolating cement inside the casing while wiping the ID of the string as cement is displaced out of the shoe. The dart and plug feature latching noses and receptacles for reliable bump and backpressure capability.
