Polished Bore Receptacle

The Polished Bore Receptacle (PBR) features a honed inner surface with high finish and low roughness parameters to ensure optimal sealing properties for tie back operations with a Seal Stem or a Bottom Set Tie Back Packer. In order for these properties to be kept during the running procedure, despite varying movement mechanisms (e.g. due to the change of temperature), which could occure during an operation, the PBR length can be adjusted.
In spite of limitations by the use of strict tolerances the design provides a defined wall thickness which guarantees ideal burst and collapse ratings. Furthermore a chamfer is available on the top end of the PBR in order to assist easy entry of different running components.
