ACT shear-out safety joint enables the positive release of the tubing string in completions with expected retrieval challenges. The joint is used between packers in single, dual, and triple completions. It is also used when rotational release is not wanted. The safety joint is easily adjusted in the field for various straight-pull release shear values. It can also be adjusted to compensate for hydraulic conditions that exist when the string is landed or conditions that are created by well treatment. These safety shear joints are keyed so torque through the tool does not load the shear screws. (Non-keyed versions are also available).
