COLOSSUS
Liner hanger systems
Enhance well stability and protect the casing.
RCB
Retrievable cement bushing
Optimize liner cementing and liner top packer setting operations
The RCB is optimized for use with the COLOSSUS CMT cemented liner hanger system and COLOSSUS UNC uncemented liner hanger system. It provides pressure integrity from the workstring to the liner toe. It remains in position throughout the running and cementing operations and enables pressure testing of liner top packers after they are set.
The system also enhances cementing operations and wellbore stability because the packoff ensures circulation of all cement behind the liner.
