SET OPEN HOLE LINER (OHL)

SUMMARY

SET OHL Systems anchor to the bottom of an existing casing string and extend into the unfinished wellbore. The expandable liner is then hydraulically expanded using cold-working process, casing-off the openhole while maintaining maximum hole size. Anchoring is achieved by expanding anchor hanger joints (expandable liner joints with bonded elastomeric bands) inside the base casing. Additional joints can also be run in different sections of the liner to achieve further zonal isolation.
