The PARVEEN ‘W’ Running Tool sets type B, C and W slip type mandrels in the tubing. The W Running Tool consists of a top sub complete with a fishing neck and sucker rod pin connection, a middle sub, a bottom sub, a collet set and an inner core. When the desired setting depth has been reached the tools are picked up to set the slips and expand the rubber element. Once set, the pin in the W Running Tool can be sheared and the prong can be withdrawn from behind the collet, allowing the running tool to release from the mandrel.
