Casing string technicians are responsible for assembling the casing string and ensuring that they use the proper components for a specific well. They also inspect the casing shoe and other features to make sure that they are working properly. It can be costly to lose a casing shoe, so workers strive to keep it in good shape.
Injection molding can be used to form a casing shoe. The injection mold may be designed to have the proper internal geometry for the shoe. In addition, a composite material may be used to form the body and nose of the casing shoe. When the casing shoe is formed this way, the pressure applied to the shoe will be constant.
