ReGen™ Fullbore Liner Tieback System
  Onshore        Field-proven Technology
The REGEN™ Fullbore Liner Tieback System (FLTS) is the industry’s first tieback system designed for specific use in recompleting existing wells with the REGEN™ 4" x 5-1/2" liner systems.
Historically, isolation or other wellbore integrity issues in a refrac well could mean a shortened or cancelled refrac stimulation, as the options to deal with such issues were limited. With the FLTS, an operator can install a fullbore frac string to restore isolation and integrity, allowing the operator to move forward with their refrac program.
The FLTS allows operators to install a frac string and still maintain the capability to run full size frac plugs and pump at frac pressures up to 12,000psi.  
 
Benefits
	- The FLTS can be installed in wells pro-actively, giving operators peace of mind in the event of isolation issues.
 
	- The FLTS allows for the use of conventional frac plugs, saving money compared to high expansion plugs.
 
	- Custom high-pressure, high-temperature seals - ensure high pressure integrity even after repeated hot stabbing into the Liner Tieback Receptacle.
 
	- Single piece mandrel provides a fullbore ID through the FLTS seal assembly
 
REGEN™ Fullbore Liner Tieback System can be used in conjunction with the REGEN™ Liner Hanger system and the REGEN™ Drop Off Sub
