Abstract
A downhole tool, a retrievable bridge plug system, and a method. The downhole tool includes a release mandrel, a plurality of slips disposed at least partially around the release mandrel, an upper cone disposed at least partially around the release mandrel and on a first axial side of the plurality of slips, a lower cone disposed at least partially around the outer mandrel and on a second axial side of the plurality of slips, and a collet positioned axially and radially between the release mandrel and the lower cone. The collet is configured to prevent downward movement of the lower cone relative to the release mandrel at least when the downhole tool is in a run-in configuration and when the downhole tool is in a set configuration.
