Fix micro annuli and cement channels behind pipe on wireline

Page last modified
May 22 2023

The Falcon Local Expander is a wireline deployed tool that locally deforms a casing or tubing to lock up and solidify the cement and thus remove sustained casing pressure (SCP), surface casing vent flow (SCVF) and other expressions of annular fluid that are widely encountered in zonal isolation issues. It avoids risky and costly measures such as milling and / or cement squeezing. It makes rigless abandonment possible, can avoid cross flow or avoid fracs going along the outside of the cemented tubing.


Cost effective
Quick (around 30 min per set of dents)
No change to the internal diameter
No holes in the casing or tubing
Proven success in many wells already
Needs drift access to deployment area


Areas of Application Wells, well services, abandonment.
Certification/ Licenses CE certified.
Compliance With abandonment criteria; explosion-proof tool for zone 2.
Capabilities 600 ton of force for the 7” tool; capable of denting casings/tubings from 50-135 kpsi of yield strength.
Sizes 4 ½”, 5 ½”, 7”, 7 5/8”, 9 5/8”, 13 3/8”. Other sizes on demand.
Environment No materials are used and no scrap is produced | Reduction in CO2 by not having to run a rig for lenghty times
Cost Large cost reduction is possible due to the deployment system (wireline vs rig / pump units).
Safety No explosives or high pressure hydraulics | Removal of surface hazards associated with rig work and pumping
