The LiMAR® Calibration Sub is made up to the Adjustable Spring Jar and by simply rotating the tommy bar at the end of the Calibration Sub load is applied across the latch mechanism of the Spring Jar. Simultaneously, a hydraulic piston will compress a fluid filled chamber and the resultant pressure created is registered on the pressure gauge in psi. This reading is directly proportionate to the tripping force in pounds force and indicates the tension required to activate the Spring Jars down hole.
TOOL APPLICATIONS:
To function and correctly set the activation point of the LiMAR® Adjustable Spring Jar at surface prior to deployment
DESIGN FEATURES & BENEFITS:
Compact, one-piece Calibration Sub
Simple, robust design ensuring ease of operation for the end user
Manually operated, internal piston excludes requirement for additional hand pump and hose
Directly proportionate piston pressure (psi) to the tripping force of the LiMAR® Spring Jar (lbs) making calibration simple
Optional protection and transportation case available
Suitable for on-toolstring Spring Jar adjustment
Bleed screw feature for removal of air from hydraulic chamber
Selected components QPQ treated
