Washover shoe is a downhole tool routinely used in fishing operations to prepare the top and outside surface of a fish, generally to allow an overshot or similar fishing tool to engage cleanly on the fish. In some cases, the outer portion of a fish may be milled out to allow the body and remaining debris to be pushed to the bottom of the wellbore.
The washover shoe is also called as oriented washover mill shoe, rotary shoe, which is used to remove all kinds of dirties between pipe strings and casings. The washover shoe is applied to wash over cements, hard sand settings, gypsite and crystals calcium carbonate in the annular space, etc.
