In a preferred embodiment a centralizer, a radially extendable cutting tool, and a fluid jet cleaning tool are run into a wellbore where the radially extendable cutting tool cut the window through the inner production tubular and the fluid jet cleaning tool removes the remaining's cement and other debris allowing a plug to be placed within the window. In another embodiment a centralizer and a first extendable cutting tool may be run into the well where a small window is cut and then the centralizer first extendable cutting tool are removed from the wellbore. A centralizer, a second extendable cutting tool, and a fluid jet cleaning tool a run into the wellbore.
