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.
