Abstract
A seat forming apparatus for use in a downhole tool comprising a driving member and dog elements that are disposed and movable within an outer housing of the downhole tool has been disclosed. The dog elements align in grooves recessed in the outer housing of the downhole tool in a first position and disengage from the grooves in a second position. The driving member travels in a reverse direction and enables the dog elements to move from the first position to the second position and form a seat in the downhole tool. The seat formed has an inner diameter smaller than the restriction element to allow the restriction element to be seated.
