Abstract
Embodiments relate to methods and devices for improved liner drill-in operations. Specifically, embodiments may provide the capability to selectively allow rotation of the liner, even once a packer has been set. Typical embodiments might couple a port sealing collar (that can selectively seal or open a port in the liner) to a selectively lockable swivel joint, for example.
