Abstract
The system and method for setting a completion tool within a wellbore includes assembling a mandrel, inner sleeve, piston, outer sleeve, and dog member. In a first locked position, the dog member abuts against the indentation of the mandrel and the locking surface of the piston. The dog member is friction fit between the piston and mandrel so that movement of the completion tool corresponds to movement of the mandrel. The mechanical link, such as shear pins, of the completion tool is protected by the dog member holding steady on the mandrel. When the completion tool reaches the desired location, a pressure pulse opens a chamber between the sleeves to transition to a second released position. The dog member releases from the mandrel to be housed in the chamber, when movement of the mandrel sets the completion tool by the mechanical link, such as shear pins.
