Stage collar for cementing operations in oil and gas
The granted patent US12024977B2 introduces a novel stage collar designed for cementing operations in wellbores. The stage collar comprises several key components, including a barrel, an activation sleeve with fluid openings, an activation ring with a seat, and multiple sets of shear fasteners that couple these elements together. Additional features include a setting piston, a closing sleeve with its own fluid openings, and various chamber housings that facilitate fluid flow and pressure management. The design allows for controlled activation and closure of the collar during cementing operations, enhancing the efficiency and reliability of the process.
The patent also outlines a method for operating the stage collar, which involves running the collar into a wellbore and sequentially pressurizing plug members to shear fasteners and open fluid pathways. This method ensures that cementing fluid can be effectively pumped into the casing annulus. The process includes adjusting shear fasteners from the exterior of the collar, managing pressure differentials, and utilizing chamber housings to facilitate the movement of a packer and slips that engage the casing. The detailed claims emphasize the innovative aspects of the stage collar's design and operation, which aim to improve the performance of cementing operations in the oil and gas industry.
