Apparatus for oil well completion using retrievable rotating packer hanger

Abstract

The invention presents a retrievable packer assembly designed for enhanced downhole operations. Featuring a bidirectional internal coupling subassembly, the assembly efficiently transfers torque and downward force, overcoming resistance during descent. Safeguarding joint integrity, bypassing subassemblies are integrated. The lowest section houses a unique retrieving subassembly, allowing controlled packer release for retrieval. The assembly incorporates isolating, anchoring, and locking systems for versatile functionality. A groove shaft in the coupling subassembly facilitates topside drive engagement, ensuring seamless torque transfer. Innovative mechanisms, including a sheer ring and support ring with a slotted component, enable controlled release. This retrievable packer assembly offers a robust solution for diverse well conditions, prioritizing operational efficiency and component integrity.
