Resources
In some coiled tubing applications, it may be necessary to seal on various diameters of the bottomhole assembly (BHA). The annular design will seal on an open hole up to 5.50-in. diameter. The hydraulic operating piston of the annular BOP is designed to efficiently actuate the piston, thereby closing the packer and minimizing the effect that well pressure has on the pack-off. The normal 1,500-psi hydraulic pressure is the maximum required for BOP operation over the full 10,000-psi working pressure range.
Features and benefits
- Designed for coiled tubing, snubbing, and wireline operations
- Quick and efficient packer replacement and a shorter overall height
- Configuration has a studded body for quick removal of the bonnet and rapid packer removal
- Lightweight and compact design
- Includes vented ports between the hydraulic system seals and the wellbore seals
