Roller Stem
Roller
Stem is a special type of stem used to assist upward and downward jarring
forces where deviation in a well is encountered and jarring using
traditional jars is unsuccessful. While sliding on the tubing wall,
Roller Stem helps to reduce wellbore friction thereby prevent hang up
against the tubing.
