RRT
Right-hand-release running tool
Mechanically or hydraulically set liner hanger systems that require high torque to drill the liner.
Solid-body mechanical-set liner hanger
The SBRD solid-body mechanical-set liner hanger is designed for vertical and onshore wells where the workstring can be manipulated to set the hanger. Its solid-body construction maximizes reliability and minimizes lifetime well costs while delivering the performance ratings you need.
The SBRD comprises the hanger body or mandrel, one or more sets of cone pads, slips, and a cage assembly to carry the slips. The cage contains a J-slot and drag springs. When the liner reaches the target depth, mechanical manipulation of the hanger body moves the cage J-slot from the running position to the setting position, bringing the slips into contact with the cones. A gauge ring protects the slips while the hanger is run into the wellbore. Multiple cone designs minimize stress in the supporting casing.
