1. ShortSTAK™ Composite Frac Plug
The ShortSTAK Composite Frac Plug is used to isolate stages during multistage stimulation. The patent pending design provides the operator with the shortest plug available on the market. The length and material minimizes milling time and maximizes bit life.
The patent pending barrel-slip/element system eliminates the elements extrusion gap for a reliable 10,000 psi rating.

2. ShortSTAK™ Composite Frac Plug
Endurance Test (4 hours 36 minutes):
A 4-1/2” 15.10# ShortSTAK was set in a piece of casing, then heated to temperature. During this testing the pressure was cycled between 6000 psi and 0 psi, then increased to 10,000 psi. The temperature was increased from 180°F to 250°F during the test. At the end of this 4 hour and 36 minute test the ShortSTAK plug lost only 115 psi on a 32 oz. volume.
