Like two tools in one, Impact Selector’s Intensifier functions as an acceleration tool or as a shock absorber device, depending on where it is positioned in the tool string.
Wireline jars rely on stored energy from both internal springs and in the stretched wireline to create impact forces. If additional energy is required, then the Intensifier is placed above the jar to increase the energy storage capacity of the system using a powerful spring stack.
When placed below the cable head, the same spring stack will absorb shocks —created by perforating, for example—from below to protect the rope socket and wireline from damage.
