REAMING SHELLS
Main Features
The reaming shell is usually situated between the outer tube and the coring bit.
The purpose of the reaming shell is two-fold: to gauge the hole diameter and to stabilize the core barrel during the drilling to avoid the vibration,and also, associated with stabilizer, the deviation.
This stabilization helps to avoid premature wear on the outer tube of the core barrel.
