The Annular BOP is a key well-control device providing a flexible and reliable seal for the wellbore. Unlike ram-type BOPs, it uses a rubber sealing element to close around drill pipes, tubing, or an open hole, making it suitable for various drilling and workover operations.
Key Functions:
Versatile Well Sealing: Seals different diameters and shapes, including drill pipes, casings, or open holes.
Pressure Control: Maintains well control under high-pressure conditions, preventing uncontrolled flow of fluids, oil, or gas.
Safe Operations: Provides rapid closure during well kicks, completion, or intervention, protecting personnel and equipment.
Design & Construction:
Body Material: High-strength forged steel, heat-treated for durability.
Sealing Element: Advanced elastomers (e.g., nitrile rubber or polyurethane) with reinforced inserts for high-pressure and high-temperature resistance.
Operation: Hydraulically actuated, with quick-close and controlled opening.
Standards Compliance: Built to API 16A and other international well-control standards.
