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. Efficient Use of Saltel Xpandable Technology in Unconventional Wells This live webinar explains how patches and packers using expandable steel technology deliver unrivaled benefits when remediating casing and cement failures in unconventional wells. VIEW ON DEMAND 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. 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. Cut and Reconnect the Casing Cut off the damaged casing and leave a stub that can be connected to a new casing string.
