Abstract
A material that dissolves or disintegrates is secured to an inside surface of tubular goods before swaging or expansion takes place. The material remains in position as the swaging occurs and post expansion is removed leaving a recess of a desired shape to function for a variety of purposes depending on its shape and location. At the end of a tubular it can serve as a bell into which the next string is expanded for a monobore completion. In other locations in a tubular it can function as a landing collar for a variety of tools. It can also function as a seal bore as the added material is removed preferably with water. The preferred material is an alloy of aluminum, tin and zinc.
