Recover Stuck Casing
Cut and pull stuck casing above the stuck point and reconnect to the casing stub
When a casing string has become stuck and cannot be freed when running in the well, options to recover from this can be limited. With the Casing Reconnect system, the casing can be cut anywhere above the stuck point and removed from the well. The system can now be run with the casing hanger correctly spaced out to land in the wellhead, returning integrity to the well with a fully certified V0 metal-to-metal connection.

Replace Damaged Casing
Reestablish casing integrity of corroded, collapsed, or leaking casing that cannot be repaired by a Saltel casing patch
When the casing has become worn, corroded, or damaged or has collapsed, it may no longer be possible to withstand the pressure test required to complete the well. With the Casing Reconnect system, all the damaged casing can be cut and removed down to the first joint of competent casing, and new casing of the original size and drift can run. The Casing Reconnect system is placed over the cut casing stump and the casing hanger landed. Full metal-to-metal integrity is now restored. Qualified to ISO 14310 and ISO 13679 standards.

Restore Damaged Wellhead
Efficient replacement and repair of casing hanger, wellhead, or both
Should damage occur to a casing hanger seal or wellhead spool, the Casing Reconnect system can be used to quickly return integrity to the well. After plugging the well, the casing would be cut below the casing hanger and removed from the well. Once the surface equipment has been removed, the compact spool can be repaired or replaced. A new casing hanger and the Casing Reconnect system can now be installed to return the well to its design condition with robust metal-to-metal connection.

Facilitate Well Reentry
Reinstate exploration, temporarily plugged, and abandoned or previously decommissioned wells
The Casing Reconnect system can be used to reinstate casing strings to surface when they have been previously cut for plug and abandonment or suspension purposes with a fully ISO-qualified metal-to-metal connection. This solution can be utilized in numerous casing strings within the same well. Sizes from 7 up to 14 in.

Gas-Tight Reconnection to Surface Enables Reentry into Abandoned Exploration Wells and Avoids Redrilling
Novel use of Casing Reconnect system cost-efficiently converts two plugged and abandoned wells into producers.
Read Case StudySimplify casing repairs and minimize costs
Remediate damaged well casing without lengthy fishing operations or costly sidetracks by using the Casing Reconnect metal-to-metal, gas-tight casing repair system to replace stuck or damaged casing. The robust, gas-tight seal endures for the life of the well and maintains fullbore access after installation, which means it can also be used to realign spaceout if needed.
This full-axial-load-bearing metal-to-metal reconnection solution keeps your drilling program on schedule, secures well integrity for plugging and abandonment (P&A) operations, and can be used to connect a subsea wellhead to surface.
Replace casing during drilling
During well construction, the casing may become stuck at a point close enough to the intended landing depth to still be viable.
To avoid fishing or sidetracking, you can cut and pull the casing anywhere between the wellhead and the stuck point and then run a replacement casing with the Casing Reconnect system receptacle at the bottom.
The casing stump is then morphed into the Casing Reconnect system receptacle to rejoin the two strings with a high axial-load-bearing metal-to-metal seal.
