WELLBORE ANNULUS SEAL SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18070001 titled 'WELLBORE ANNULUS SEAL SYSTEM
Simplified Explanation
The annulus seal system described in the patent application includes a retention plate mounted to a tubing in a wellbore, along with an annular isolation system coupled to the retention plate. The annular isolation system consists of a bottom holding plate, a seal element, a torque plate, and a top holding plate. The seal element is compressed between the bottom holding plate and the torque plate to seal the annulus between two tubings, with the top holding plate controlling the movement of the torque plate.
- Retention plate mounted to tubing in a wellbore
- Annular isolation system with bottom holding plate, seal element, torque plate, and top holding plate
- Seal element compressed between bottom holding plate and torque plate
- Top holding plate controls movement of torque plate
Potential Applications
The technology can be applied in oil and gas drilling operations, well completion processes, and other industries where annulus sealing is required.
Problems Solved
The annulus seal system solves the problem of effectively isolating and sealing the annulus between two tubings in a wellbore, preventing fluid migration and ensuring well integrity.
Benefits
The system provides a reliable and efficient way to seal the annulus, reducing the risk of leaks and improving overall well performance and safety.
Potential Commercial Applications
- Oil and gas drilling companies
- Well completion service providers
- Offshore drilling operations
Possible Prior Art
One possible prior art could be traditional annulus seal systems that may not offer the same level of control and precision in sealing the annulus as the system described in the patent application.
What materials are used in the seal element?
The patent application does not specify the exact materials used in the seal element. However, common materials for seal elements in similar applications include elastomers, rubber compounds, and synthetic polymers.
How is the adjustment mechanism on the top holding plate operated?
The patent application does not provide detailed information on the specific operation of the adjustment mechanism on the top holding plate. Typically, adjustment mechanisms in similar systems may involve manual or mechanical controls to regulate the movement of the torque plate in the longitudinal direction.
Original Abstract Submitted
An annulus seal system includes a retention plate mounted to a tubing in a wellbore at an uphole longitudinal end of the tubing and an annular isolation system coupled to the retention plate. The annular isolation system includes a bottom holding plate positioned in an annulus between two tubings, a seal element residing on the bottom holding plate to seal the annulus between the tubings, a torque plate, and a top holding plate. The seal element is positioned between the bottom holding plate and the torque plate, and the torque plate moves in a longitudinal direction toward the bottom holding plate to compress the seal element between the bottom holding plate and the torque plate. The top holding plate mounts to the retention plate, and includes an adjustment mechanism engaged with the torque plate to control movement of the torque plate in the longitudinal direction.
