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
