Guide Shoes are attached to the lowermost end of the casing string to provide a low-cost method of enabling the casing to pass ledges or obstructions in the well-bore, which aids bit re-entry. The cement guide shoe may be used in combination with any type of collar. It efficiently guides casing past sidewall irregularities.
The guide shoe in drilling operation 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.
Orifice is sufficiently large as to allow tripping balls, tubes and debris to exit the casing without obstruction
Rounded nose assists while running casing in hole
Load bearing capability for setting at bottom
PDC drillable
Available in sizes 4 1/2"- 30"
API standard threads are cut in-house. Other premium and custom threading can be supplied and cut through our extensive vendor base
