Claim 11:
12. A plug retrieval tool, comprising:
a mandrel lowerable into a wellbore;
a retrieval head coupled to the mandrel for selectively latching onto a plug;
a shroud telescopically coupled to the mandrel about the retrieval head and moveable repeatedly between an extended position for displacing debris on the plug and a retracted position for moving the retrieval head closer to the plug; and
a resistance mechanism including first and second fluid chambers defined between the mandrel and the shroud, a valve plate separating the first and second fluid chambers, and one or more valves arranged in the valve plate to constrain flow from the second fluid chamber to the first fluid chamber to provide resistance when the shroud is moved toward the retracted position.
