Claim 15:
16. A method comprising:
lowering a plug retrieval head into a wellbore on a mandrel with a shroud telescopically coupled to the mandrel about the retrieval head;
with the shroud in an extended position, displacing debris on the plug using a lower end of the shroud while resisting movement of the shroud to the retracted position on the mandrel;
after displacing debris, lowering the mandrel to move the shroud to a retracted position on the mandrel thereby moving the retrieval head to the plug;
latching onto the plug with the retrieval head;
identifying one or more failed attempt to latch onto the plug with the retrieval head;
with each failed attempt, raising the mandrel, moving the shroud back toward the extended position, further displacing debris on the plug using the lower end of the shroud, and lowering the mandrel to move the shroud back to the retracted position;
resisting movement of the shroud using a restricted fluid flow each time the shroud is moved toward the retracted position; and
removing the plug from the wellbore on the retrieval head.
