The IBOP is a specialized well-control device installed inside the drill string or production tubing, providing secondary well shut-in protection. It serves as an additional safety barrier during drilling, completion, or workover, especially in high-pressure wells.
Key Functions:
Internal Well Sealing: Seals the internal bore of the drill string or tubing, preventing uncontrolled flow of drilling fluids, oil, or gas.
Emergency Well Control: Acts as a rapid-response device in case of abnormal pressure or well kick.
Safe Intervention: Allows safe tool and equipment changes without exposing the rig to uncontrolled flow.
Design & Construction:
Body Material: High-strength alloy steel, forged and heat-treated for durability.
Seal Components: High-performance elastomers (e.g., polyurethane or NBR) for reliable sealing under pressure.
Operation: Hydraulically or manually actuated with quick-close capability.
Standards Compliance: Built to API 16C and other international well-control standards.
