The plug of choice for multizone plug-n-perf is the Ball Drop. Once the wireline is out of the hole, a ball is dropped and pumped down to seat against the top of the plug. When the ball seats, the fluid hammer helps break down tight formations. Available in three ball densities.
The Ball Check plug is typically used in vertical applications where pumpdown is not required. This allows the operator to pressure test each plug.
This unique design allows the operator to pressure test each plug without the risk of the guns not firing, which results in a tractor run. The ball can be flowed back to the surface and another tool string pumped down. The Ball in Place plug reduces costly frac time and fluid by eliminating the need to pump a ball down.
The Bridge Plug allows the operator to test the casing and plugs before perforating, or it can be used as a cap plug. It holds pressure from below and above. The top venting feature allows for equalization when drilling before releasing top slips. The Bridge Plug is available in dual cast iron option or composite top slip.
The Dummy plug is used for pumping guns down when rate or pressure is an issue. The HELISEAL on the Dummy plug doesn't cause the tool string to float when falling in the vertical. It can be pulled out at speeds of 250 ft/min. It can also be sheared off with a setting tool and left downhole. The Dummy plug comes in two configurations and is reusable by replacing only the HELISEAL.
