Shear Safety Joint
Shear Safety Joint
The rotational shear-out safety joint provides a reliable method for positively releasing the tubing string in completions where retrieval may be challenging. It is typically installed between packers in single, dual, or triple completions and is also suitable for applications where rotational release is undesirable.
This safety joint can be easily adjusted in the field to achieve specific straight-pull shear release values. It can also be configured to account for hydraulic forces present during string landing or those introduced during well treatments.
Features
- Can be locked in open or closed position.
- Large by pass area for fluid circulation.
- Top connection keyed to prevent torque overload.
- Unloader seals protected from fluid flow in open position.
- High strength alloy steel construction.
Benefits
- High temperature and high pressure rating for severe service.
- High torque rating for manipulating heavy drill pipe into tight spots.
- High hanging weight capacity for long tail pipe below packer.
Applications
- The simple design provides a reliable, inexpensive method for straight-pull emergency shear release
- Easily adjustable shear values.
- Fracturing, acidizing, and remedial workovers
