FLEX - Falcon Local EXpander
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.
Pro/con
Cost effective
Quick (around 30 min per set of dents)
Rigless
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
Specification
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
