Mechanical Shear Type Disconnect

Product Code: WBI PDS 0018

The Mechanical Shear Type Disconnect is a simple and effective emergency release tool which can be used in place of a ball activated tool in applications where a drop ball cannot be used, such as below a mud motor. It allows a stuck bottom hole assembly (BHA) to be detached at a pre-determined tensile load.

The tool is typically used in fishing applications where a motor is used to 'bait' a fish. Once the fish has been engaged with the appropriate fishing tool an overpull is applied to shear out the disconnect at a predetermined tensile load leaving a standard internal 'GS' type profile for subsequent fishing / jarring operations.

Features:

  • Simple and effective emergency release joint.
  • Torque-thru feature.
  • Standard internal fishing neck profile.
  • Variable shear ratings.
  • Easy field redress and set-up.
