ReLine DL - Expandable Liner

This provides a significant ID advantage when compared to a conventional liner string, enabling passage of optimized bit, casing & completion designs, and ultimately maximizing production.

The ReLine DL system is a bottom-up expansion design which uses hydraulic pressure to drive the expansion cone from the bottom of the liner to the top.

Applications

• Isolation of unwanted water, gas & sand ingress

• Corrosion isolation

• Isolation of tubular leaks

• Velocity string

• Isolation of leaking or compromised completions components:

• SSD (Sliding Side Door)

• ICV (Inflow Control Valve)

• ICD (Inflow Control Device)

• GLV (Gas Lift Valve)

• CIV (Chemical Injection Valve)

The system allows for cementing operations prior to expansion and facilitates a fully testable, anchored liner tie back into the previous shoe, ensuring life of well integrity with the added value of optimized wellbore diameter.

Primary elastomeric seal elements can be incorporated to the DL system in conjunction with swellable elastomers to provide instantaneous high-pressure liner to rock isolation at the launcher, and zonal isolation of the open hole where required.
