Scab Liner Systems
A scab liner system is run for well repair applications in flow control or casing/tubing repair situations. Due to tight restrictions in a well, two Thru-Tubing inflatable packers may straddle a zone, making a Thru-Tubing Scab Liner. Alternatively, sequential ECP (External Casing Packers) may be run for horizontal or vertical separation in open hole or cased hole. Either system can be disengaged downhole via a hydraulic disconnect or mechanical over pull.
Applications
Common isolations include:
- Casing / Tubing Damage
- Casing Perforations
- Production Zones
- Open Hole Fracturing
- Small O.D. for running through tubing or tight downhole restrictions.
SINGLE SET PACKER SCAB LINERS
- Run-on tubing or drill pipe in cased or open hole environments.
ECP SCAB LINERS
- Run on casing string in vertical and horizontal wells.
