A barrier forming apparatus is deployable through a conduit component in a well. The apparatus has a snap latch that removably couples to a work string. A mandrel element in the apparatus is selectively moveable with the coupling element. A plurality of locator dogs on the apparatus are spring biased and are activated when pressure is applied to a piston in the apparatus, which release the locator dogs. Once activated, the locator dogs engage a first grove the in the conduit component. When the work string is pulled up while the apparatus is held by the locator dogs, a plurality of locking dogs are activated by movement of a mandrel element caused by the work string. The locking dogs engage second grooves in the conduit component. Continued pulling of the work string moves a cone attached to a distal end of the mandrel element, and the moving cone deforms a barrier element positioned between an end of the apparatus' housing and the cone. The deformed barrier element forms a barrier in the conduit component between upper and lower completions. Removal of the barrier is achieved by reversing the steps. The apparatus can be used to isolate an expandable sand screen section below the conduit component.
