KCI IBS Gels Isolation Barrier Systems
Ball Valves & Pipeline Isolations Deployed as a fluid and transforms to a gel to provide a seal / barrier directly into or between leaking
production ball / gate e.g. pig launcher and production trees. Product can be converted back into a
fluid and dispersed within the system or pigged out as solid.

Annulus & Packer Isolations
KCI IBS Rigless Well Integrity Isolation Barrier Systems
Deployed as a fluid, transforms to a solid flexible membrane material when it reaches the target depth to
provide a seal directly at the problem area - Packer Element, Casing Shoe or Casing Hanger.
Annulus Isolations
Ideal for: Rigless Low Cost Well Intervention - Downhole Sealant Applications:

Position the IBS-SX below the Hanger
to protect the casing hanger seals with communication to
the tubing
Advantages
• Maintains balanced pressure in the annulus
• Protects wellhead from harmful well fluids and gasses
• Protects wellhead seal structures from constant exposure to well pressure
• Prevents gas escape to atmosphere
• Sealant can be broken back to fluid state when required (surface only)
• Allows monitoring of annulus pressure
• Allows venting of annulus pressure when required
