Abstract
A cutting module to sever a tubing in a well includes a piston and shear blade. The piston includes at least two moveable telescoping elements, which are adapted to expand the first piston from a retracted length to an expanded length. The shear blade is connected to the piston to sever the tubing in response to the piston expanding from the retracted length to the expanded length. The cutting module may be located below a safety valve in the well.
