In the January issue of the Journal of Petroleum Engineering, SPE journalist Steve Rassenfoss wrote an excellent article about the team from NTNU, winners of the 2017-2018 Drillbotics competition. It is written from a personal viewpoint from interviews with the team members and university supervisors.
“They studied the bit/rock interaction via offline testing. They calculated the reactive torque acting on the thin-walled aluminum tubing that DSATS forced them to use. They made an informed decision to drill a little bit slower, knowing this would increase their ability to avoid pipe damage. They fully understood the concept of trade-offs that affect nearly every engineering decision.”
