The ETANG Polished Bore Receptacle (PBR) is a critical component in liner and tie-back completion systems, designed to establish a reliable, dynamic sealing interface that accommodates tubing movement.

　　Its body is manufactured from high-strength material with precision honing, where tight tolerances and a superior surface finish ensure long-term, gas-tight sealing performance with the seal assembly.

　　A smooth lead-in chamfer at the top ID guides tools easily into the PBR, preventing seal damage even in deviated or horizontal wells. The lower end of the PBR can be optionally connected to a liner packer or a setting sleeve to adapt to various completion strategies. Additionally, it can be paired with a bottom-set tie-back packer and tie-back seal stem to form a complete tie-back system.

　　Features:

　　Reliable dynamic sealing

　　Reduced running risk

　　Adapts to various completions

　　Enables full tie-back capability
