Underreamer madness!!!

Here is a quick photo of the underreamer being tested, below the rig floor, before it is deployed. You can see the arms of the underreamer partly extended with the spray of the water. There is a tri-cone drill bit positioned 6.5 m beyond the end of the underreamer, to drill into basement ahead of the arms (which we will use just for drilling sediment). Excellent!!!
