The last drilling phase bit 8 ended several hours
Mark Zoback and Steve Hickman examine the damaged bit.

The last drilling phase (bit #8) ended several hours prematurely yesterday when the drill pipe showed a sudden increase in torque. When the pipe was tripped out of the hole, it was discovered that the drill bit had lost one of its three cones. This has caused a delay of about 18 hours as we've needed to make a trip into the hole with a mill to grind up the cone on the bottom. We expect to resume drilling at around midnight.
