Challenges
Shale at 15ft down to grade. Averaged 22ft/hr on the pilot and burned two rock bits.
Tips for the next crew
Budget double the pilot time and run wireline — walkover is useless at that depth here.

Recycling on shale is the move. We ran the same setup two blocks south with the same numbers.
