You need to watch and see till almost the end. You will see what wrong.
The object is accidentally dropped into the wellbore. This would cause a lot of time and money to fish it.
These are some comments from people.
Brennon Larose – All a person has to do is close blind Rams break the bit hoist up put the hole cover on then screw the bit off by hand then if it ever did fall in the hole the bit would be sitting on the blind Rams
John Osborne – People saying close blind Rams are in my opinion wrong Rams only supposed to be closed in an emergency closing Rams to stop things falling down hole is bad practice there is always another way lifting cap tugger ensure dog collar was secure this could have been avoided easily.
You don’t close blind Rams to protect hole this is bad practice dog collar should be properly maintained and to lift bit out of hole like this is wrong as soon as bit sub disconnected lifting cap should have been installed no matter how small bit it and then tugger attached closing Rams for this is wrong.
If you closely watch video it’s clear that this was not a bit in hole they had side door casing elevators on bales which appear to be sized for approx 3 1/2 to 4 1/2 so they had probably just pulled out hole old casing which historically is when things start to go wrong crew fatigue excitement of job nearly complete a time when driller and crew should be more vigilant human error yes but totally avoidable.
Jason Abel – This what fast tracking & little experience results in, oh and a driller with his head up his arse. Why wasn’t it screwed onto bit sub first while hole was covered.
Venus Houde – How are you supposed to monitor for returns with closed blind rams? Always monitor open hole. Always cover the hole on the rig floor. They should have made up the bit to the sub and the motor or collar before ever putting it in the hole.
Mickey Turner – Well bit breaker latch was in need of repair. So keep your equipment in good shape. And don’t just through it when thru with it (which I have done). Make sure your on same page with anyone on a lift. No matter how small or big. As for as blinds being closed that’s day 1 stuff.
How can we prevent this issue?
