TOOLSTRING EQUIPMENT
Roller Stem
Roller stem is used t allow for easier deployment of subsurface equipment into deviated wellbores
by allowing the weight of the toolstring to rest upon wheels that travel down the ID of the tubing or
casing In the wellbore.
Roller stem can typically be converted from one size to another by changing out the rollers.
Applications:
Roller stem may be used to deploy bottom hole instruments or tools into deviated or horizontal wellbores.
Roller stem may be used to mitigate drag in deviated, dog legged, or non vertical wellbores.
