ChallengeWater shut-off
The Isealate Springblade Patch is a unique downhole repair solution, utilizing a pre-rolled laminate steel sheet to remediate leaking or damaged tubing.
With no more than a 4-10 mm effect on the inner diameter (ID), this patch-thru-patch solution offers all the benefits of straddles and larger steel patches, but with a more rapid deployment capability and total flexibility for customized relining, repair, and well integrity.

Overview
Each Isealate Springblade Patch is deployed in a pre-rolled form, held under tension by shearable clamps.
When run in hole, the patch is delivered to the precise location required to cover the leaking or damaged section of tubing, and is quickly expanded by a setting tool controlled at the surface.
The patch immediately conforms to the tubing ID, and a heat-activated resin (pre-applied) further facilities complete sealing.
The slim design allows for subsequent patch-thru-patch deployments and does not interfere in any way with future interventions.
