Scab Liner SystemsScab 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

THRU-TUBING SCAB LINERS

  • 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.
