Product Description

 Toolstring Equipment Wireline Jars Spring Jar Downhole Tools

Spring Jar
Spring Jar, similar to a Hydraulic Jar, is an upstroke jar designed to place between stem and mechanical link jar and is suitable for
deviated gas well when conventional jar up action is not possible. An upward line pull exerts tension on the stretched wire and allow
compression of the main disc spring to a point that the trip keys expand into the recess and quickly released the jar rod to strike up
creating an upward jarring action to the toolstring. For repeat operation, resetting is conveniently done by slacking the line tension,
allowing the stem weight above to close up the jar.
Spring Jar are preferred over Hydraulic Jar in a gas wells to avoid 'gassing'. Spring Jar is supplied with a set of adjustment/release tools
to aide with pre load / adjust setting of firing point and manual unloading. An optional Spring Jar Calibration Sub is also available
upon request.
