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:
I see no problem P/U the blocks & and go back to making hole, just saying
or
Top of the picture suggests possible drill line part...just a guess on abnormal drill line wear without cut/slip?
The Second Contestant:
Maybe hydraulic the pipe out of the hole. or You can pull down sometimes when pushing isn't enough!
or
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
Another Exam
The First Contestant:
- Collapse due to external pressure within the annulus. or No volume in tubing. Down-hole pressure collapsed tubing
The Second Contest :
- Negative pressure test gone wrong,pressured up back side to high and probably empty tbg or they pulled out too fast and swabbed the brine out the tubings.
The Third Contestant:
- Three things I can think of :
1- Pressured annulus above max tubing collapse .
2- Parted tubing and rotated washover pipe on to fish with power swivel.
3- Dropped tubing to bottom then latched with wash over pipe.
The Fourth Contestant:
- Pressure differential on backside greater than inside tubing when pulled! Been there done that on fishing jobs easy money.
Fifth Contestant:
- Running production pipe in the hole on a snubbing rig closed the slips while snubbing the joint in.
Sixth Contestant:
- While run in hole to drilling in the top hole .. The jar is open . And string is fall in the hole .. While fishing the H.W is damage .
