Our cementing plug and dart technologies remove previous fluids with efficient fins that cleanly wipe the inside diameter (ID) of the casing or drillpipe.
Our darts provide a reliable surface indication of downhole cementing events, including the pressure increase that occurs when the top plug bumps on the float equipment to signal that displacement is complete. We manufacture a comprehensive line of standard and customized cementing plugs and darts for any application:
Casing wiper plugs separate fluids during cement curing in surface casing strings.
Wiper darts separate fluids in the drillpipe or tubing string for inner string cementing.
Stage-cementing wiper-plug sets separate fluids in the casing or liner ID and open or close the stage tool.
Multiple latch-in high-pressure rupture plugs are run when cementing production or completion strings and in wet shoe applications.
Subsurface release (SSR) plug system separates fluids in the drillpipe and liner or in the casing string in subsea casing- or liner-hanger systems.
