Abstract
A lock open device for a running tool including a mandrel, the device including a collar located on the mandrel of the running tool and having an open position profile and a slot comprising a rotational travel section and an axial travel section. The lock open device also includes a top plate having a cog configured to engage with the open position profile to restrict the collar from relative rotation and a can including a pin configured to engage with the collar slot, in which the collar is rotatable upon overcoming a resistance of the top plate such that the pin is located in the axial travel section, allowing axial movement of the collar relative to the can.
