Intensifier UHD
Increases downhole jarring energy and protects against shock damage
Applications
- Slickline
- Stuck tools
Features and Benefits
- Belleville spring washers provide significantly greater force than a conventional coiled spring
- Additional energy is stored when used with an Impact Selector® jar to increase impact forces
- Short, compact design provides highly effective shock absorption to help prevent tool or wire damage
- Options available for standard and ultraheavy-duty (UHD) fishing operations
Tool Description
Like two tools in one, the Weatherford Intensifier UHD functions as an acceleration tool or as a shock absorber device, depending on where it is positioned in the toolstring.
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 with a powerful spring stack.
When placed below the cable head, the same stack of springs will absorb shocks from below created by, perforating for example, to protect the rope socket and wireline from damage.
