IX. DRILLING PHASE: DRILLING, CASING AND COMPLETION ...

Drilling fluids must be used when drilling wells with a rotary rig. The fluids are pumped down the drill string, out through holes (jets) in the drill bit and up the wellbore. The moving fluid cools and lubricates the bit and removes the rock cuttings that would otherwise collect at the bottom of the wellbore.
