Reamer shoes are specialized shoes that are attached to the bottom of a casing or liner string. They are designed to facilitate the descent of the casing or liner to the planned total depth (TD) in the wellbore, particularly in challenging conditions. Reamer shoes often incorporate cutting elements, such as tungsten carbide or polycrystalline diamond compact (PDC) cutters, which are used to remove obstructions and enlarge tight spots in the wellbore.
