Abstract

A disintegrating plug uses a setting tool to push a swage into the plug body that has external ribs that contact the wall of the surrounding tubular. The ribs retain the body to the surrounding tubular wall with frictional contact. Some leakage may ensue but in fracturing some leakage does not matter if enough volume under the right pressure reaches the formation. The sheared member during the setting comes out with the mandrel that is part of the setting tool. In an alternative embodiment one or more o-rings are used to seal while anchoring is assisted by the hardened insert(s) that can be snap fitted in using rib flexing or that can be a c-ring that is expanded and snapped in. The o-ring(s) are axially spaced from the insert(s).
