<br/><br/> Casing while drilling (CWD) technique allows the operator to simultaneously drill and case a wellbre section in only one run without the necessity to pull the drill string out of the hole . this innovative technique comes into play in time when oil and gas well drilling faces a lot of challenges. Most of these challenges are formation- related problems such as excessive lost circulation formation fluid inflx formation instability etc.
