ODEX Drilling: Adaptation of air-operated down-the-hole hammer using swing-out eccentric bit to ream casing bottom. Cuttings blow up through drive sub and casing annulus to swivel for rapid removal.
Casing Advancer: Designed to allow drilling and casing simultaneously as one integral operation, eliminating need for separate drilling and reaming processes.
