A revolutionary solution for existing wells.

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 canceled 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 maintain the capability to run full size frac plugs and pump at frac pressures up to 12,000psi. In addition, The FLTS can be installed in wells proactively, giving operators peace of mind in the event of isolation issues. It also allows for the use of conventional frac plugs, saving money compared to high-expansion plugs.

Application

The REGEN™ Fullbore Liner Tieback System can be used with cemented and uncemented liner systems: REGEN™ Liner Hanger Systems and REGEN™ Drop Off Sub Systems.
