Description

i-Jar™ has a temperature compensating system that makes it suitable for high-temperature conditions. The i-Jar is pressure balanced and tension compensated, and the accelerator can easily be set up to normal or heavy-duty operations by changing the springs. Due to its optimized design, the i-Jar has a low maintenance requirement.

The following configurations are available:

  • Shortstroke – Short overall makeup length used when rig-up heights are limited
  • Heavystroke – High-impact, robust, and reliable jar for heavy-duty applications
  • Xtremestroke – Heavy-duty jar and accelerators for fishing applications
  • Autostroke – Low-friction self-cocking jar for deviated and horizontal wells
  • Dualstroke – Reliable double-acting jar made for use together with well tractor or equivalent self-propelling device

Features

  • Temperature compensation
  • Fully pressure balanced, patented, and load-compensated time delay
  • Hydraulic module protected against gas
  • Heavy-duty properties
  • New low-friction, easy-latch system
  • Large ventilation port system in accelerator and jar
  • Modular design; easy to redress and maintain with long service intervals
 

Benefits

  • Ensures functionality regardless of well conditions; easy to use
  • High impact, even at low pull force
  • Ensures re-latching in deviated wells
  • Allows debris to pass without being trapped inside
  • Flexible and user-friendly with reduced service costs
 

Applications

  • Any wireline operation requiring high-impact, quality jars
  • Ideal for HT environments
  • Ideal for gas wells
