Casing Repair

Restore completion integrity after casing damage

Use through-tubing technology to rapidly remediate corroded and worn casing

Casing damage is often considered a problem of mature wells, suffered only after years or decades of corrosion, erosion, or wear fatigue, However, it is increasingly occurring in newer wells because of the wear incurred while installing initial casing in long horizontal and tortuous wellbores.

Casing repair options depend on the size and condition of the casing, the depth and extent of the leak or damage, and the productivity (economics) of the well. Schlumberger offers a full range of casing isolation, repair, and replacement technologies.

Isolate the Damage

Squeeze cement into the damage to restore isolation without impeding wellbore ID, or place a cement plug or mechanical packer or plug to isolate the damaged zone.

High-pressure wireline- or tubing-set cement retainer

Bidirectional barrier in cased hole wells for well abandonment or remedial cementing below the retainer. View

Patch the Casing

Run a patch through tubing across the damaged zone, and isolate the damaged casing by cementing it in place or inflating it to create a complete seal while retaining nearly full wellbore ID.

Shut Off Perforations

Save time and reduce costs and emissions by using an expandable steel patch to reliably seal off a perforated zone without restricting production from neighboring perforations or access to the wellbore below.

Cut and Reconnect the Casing

Cut off the damaged casing and leave a stub that can be connected to a new casing string.
