Abstract
Perforations in an existing borehole are covered with an expandable clad or elongated tubular that is expanded on location with the expansion equipment then removed. The clad is made of a disintegrating material such as a controlled electrolytic material known as CEM and is expanded into position to cover the existing perforations. One or more plugs are run in with perforating guns and the plugs set with the guns moved away from the set plug and fired to make new perforation. After each new perforation is made a ball is delivered to the plug to isolate a portion of the well and the new perforations are treated such as in a fracturing or another operation. Over time or with exposure to well fluids or temperatures the clad disintegrates and the original well drift diameter is regained so that subsequent production or injection is not impeded.
