AZM Oilfield Guide Shoes are attached to the lowermo t end of the casing string to provide a low-cost method of enabling the casing to pass ledges or obstru tions in the well-bore, which aids bit re-entry. The cement guide shoe may be used in combination with a y type of collar. It efficiently guides casing past sidewall irregularities.

It has the ability to circulate through down-jets/centre of the shoe while running in the hole. This provides a means of washing casing/liner to seat if required.
