DPEX energetic liner shaped charges substitute a defined amount of the inert liner components with reacting metals. These energetic components are transferred into the perforating tunnel together with the jet where a strong exothermic reaction takes place.

The result is an extreme pressure spike inside the perforating channel that will follow the path of least resistance and initiate a flow back into the wellbore. This backflow will break up the crushed zone and transport it out of the perforating channel resulting in a cleaner tunnel with increased diameter. Any possible slugs that have been created will also be eliminated. In addition, depending on the rock type and down hole conditions, small fractures may be initiated on the walls and the tip of the perforating channel.
