Xcalibur™ Jar


Provides significant downhole impact to safely return toolstrings to surface in any wellbore condition


Applications

  • Cased-hole
  • Slickline


Features and Benefits

  • Reliable, all-mechanical design unaffected by pressure or temperature.
  • Immediate downhole reset under its own weight for instant and unlimited activations.
  • Field-adjustable mechanism enables trained customer personnel to run and maintain the tools, saving time and money.


Tool Description

The Weatherford Xcalibur jar greatly increases the force available at the cable head using stored energy in compressed springs and the wireline itself to create a powerful upwards impulse on the tools. As the force acts on the bottom of the jar, the cable head is protected from the impact and remains unaffected.

The jar-activation force is easily adjusted at surface while in the string to account for different operations.

Available in a range of sizes and with all major types of monoconductor connections, the Xcalibur jar is ideal for most logging, perforating, pipe recovery, and plug-setting operations.
