It also helps guide the casing string into the wellbore by preventing it from hanging up. Some float shoes are made of high-strength drillable material and can be used to reciprocate and rotate to pass any

Casing While Drilling - CWD CWD Is one of the alternatives of controlled pressure drilling like Constant Bottomhole Pressure, Pressurized Mud Cap Drilling or Dual Gradient Drilling Casing while drilling is an alternative to conventional drilling using the casing as drilling string, drilling and casing the well simultaneously. Equipment used for casing while drilling can be either conventional with minimum additional equipment or specially configured drilling rig for this purpose. The drilling ri
