Displacement Plugs are used in diamond drilling, wireline drill rods and casing for placing cement plugs or casing pack fluid. The plugs are made of natural rubber and are designed to allow positive placement of a casing pack in the casing annulus or a column of cement grout in the hole without dilution by the drilling fluid while pumping.
Displacement Plugs are disposable - it is drilled out after the casing pack or cement slurry is pumped into position.

The main applications are:
• Placing casing pack
• Plugging back with cement
• Grouting
