Cementing Plug

Cementing Plug

Cementing plug is used to remove the mud during cementing operations. separate the cement slurry from other fluids, reducing contamination and maintaining predictable slurry performance.


Cementing plug types: bottom cementing plug and top cementing plug.

The top cementing plug has a solid body that provides positive indication of contact with the landing collar and bottom plug through an increase in pump pressure.

The bottom cementing plug is launched ahead of the cement slurry to minimize contamination by fluids inside the casing prior to cementing.

Special plug has top/middle/bottom plug used in two-stage cementing, drill pipe plug and hollow plug used in drilling liner cementing and composite plug used in composite casing.


Cementing plugs are manufactured of graded rubber that is fused upon a composite or Aluminum core.
Cementing plugs are completely PDC drillable.
Operating range of temperature with Aluminum core is up to 200 degree
Plug can be ordered for higher operating temperature and operation in either synthetic or mud fluids.
Available in 4 1/2″ to 20 “sizes + any special sizes
Conventional and non-rotating type are available
The non-rotating type can save the drilling time
