Wellbore system with adapter, retrieval tubular, piston assembly, stem, sleeve
A recently granted patent (Publication Number: US11920416B2) discloses a novel wellbore system designed to efficiently remove downhole components. The system comprises an adapter, a retrieval tubular with a bore, a piston assembly, a stem, and a sleeve forming part of the piston assembly. The sleeve is configured to apply an upward force to the adapter in response to a force applied by a piston at the casing section. Additional features include a cap forming part of the cavity, an anti-rotation feature, and a stem adapter to adjust the stem's diameter based on the casing section's diameter. The system aims to deenergize a sealing element associated with an energizing ring by reacting the force against the casing section rather than the housing.
Furthermore, the patent also covers a retrieval assembly with a retrieval tubular, a piston assembly with a sleeve and cap forming a cavity, and a stem. The flow path directs fluid pressure to the piston head, driving the stem in a downhole direction to engage the casing section and disengage the downhole component. The assembly includes anti-rotation features, a stem adapter, and different positions for engaged, disengaged, and removed downhole components. The method outlined in the patent involves coupling the adapter and sleeve to the downhole component, generating a downward force at the casing section via a piston assembly, and deactivating the downhole component in response to the force. The system is particularly useful for removing seal assemblies and can be integrated with a surface pressure control device for efficient component removal.
