Partially removed barriers from legacy rupture subs plague wells with poor production flow due to choked off tubing. The Workover Solutions EradicatR Sub System (E.S.S.) was designed to specifically address these issues and expands on the capabilities already offered by the WOS T.I. Disk. The E.S.S. combines newer dissolvable technology with intelligent ceramic well barrier technology. The unique materials and design features of the E.S.S. ensures a complete break up and removal of the internal barrier upon activation.


  • Built in Wireline re-entry guide
  • Can be setup for a variety of overbalance situations
  • Prevents well bore fluid from entering the work string
  • Available in mule shoe / box / pin connections
  • Dissolvable components reduce debris field
  • Pressure and internal impact activation for enhanced disk removal
  • Full bore ID immediately upon activation
  • Eliminates risk of poor production associated with partial disk break out


About This Product

EradicatR Sub System

The intelligent design of the E.S.S. creates a stored energy potential directly above the sub system. Once activated, the stored energy can directly act upon the barrier utilizing an internal impact device eliminating any potential for partial break up. After activation the immediate location of this energy release maximizes the water hammer effect to assist in fully removing the internal barrier. The use of dissolvable materials reduces the amount of solids that must be recovered from the wellbore further reducing overall risk to the operation. The EradicatR Sub System is available in a variety of mule shoe, box and pin connections.
