Collar lock

Term · Oil and gas · MLC-T-OAG-000749

A mechanical device designed to secure a downhole tool or component within a casing or tubing string by engaging with a pipe collar. This mechanism prevents the tool from moving axially within the wellbore, providing a stable anchor point for subsequent operations. Collar locks are often used to set packers or other completion equipment at a specific depth.
