Sometimes we need a lot of interview questions to be always ready for the interview:
This exam was in one of the personal interviews of one of the oil companies,and we collected many responses that you can read now and benefit from.
The First Contestant:
This occurred when unset down hole plug with out equalizing pressure above plug due to trapped pressure below it
The Second Contestant:
This may be from back pressure from well or Going up very fast It's called Back pressure off and also occured due to Oparet the machine with low tension wire feed lope
The Third Contestant:
Plug bit and formation pressure is greater than HP while BOP seals not holding after closing.
The Fourth Contestant:
This are some reason why it happened, bit plugged, well kick and the BOP not holding.
Fifth Contestant:
Lack of attention. If it deal carefully and make sure each and everything then any reason either it is well kick or other can not to do so.

Looks like pipe slide up indicating hydraulic out of hole possibly into pipe rams
The Third Contestant:
I’m tried working here down hole instead of doing a bit trip got stuck tried working up and down to break free but couldn’t even go down cuz you had no room to play with
or
Brakes over camming not adjusted properly or possibly linkage pin came out
The Fourth Contestant:
Don’t drill surface with 2 pumps running
Fifth Contestant:
Looks like the main line jumped the shivs and got wedged in between the rollers on the block and when the operator picked up the load it picked up the block.
Sixth Contestant:
The driller will blame it on the directional driller! No company man, TP or driller will accept accountability for any screw ups on location! “The auto driller malfunctioned!”
The seventh Contestant:
A few possibilities. Pumped out of the hole. Or Drilling with a rope on brake handle with no one watching, and it slacked off faster than it was drilling. Or Hit a bridge while making a connection, and didn't stop fast enough.
Eighth Contestant:
Chain the brake down and just hope it drills off before the tool pusher & office find out you fell asleep at your job.
or
Hydrauliced outta the hole boys , or drilled through something and went pipe light
