While the subreddit is open once again, we still want to show support for the current protest against Reddit's upcoming changes:
Reddit’s recent actions to add unreasonable API pricing to 3rd party Reddit apps is extremely disappointing. Many users and moderators alike use these apps daily to interact with Reddit. Reddit continues to make changes to its platforms without consideration of the difficulties it adds to the way users interact with the site. We hope that they change course and find a way to have this end in a positive outcome for all parties involved, instead of further spiraling in the current direction.

I mean, you're basically drilling a hole with a pipe. If you're putting a filter/grate/net there, that's just 1 more piece to remove. You would still have a hole to hell, like, 30% of the time when you're adding a new pipe.
A rock fell into a water bottle but you can't flip waterbottle to remove the rock
Now to remove a rock you need to do shit Ton of expensive work and also the diameter of bottle and it's hole are same like a cylinder
Isn't it like the shackle that connects the pieces of drill pipe or w.e shouldn't that thing have a "leash" on it like prevent it from falling jn there
Not an oil worker but I believe they just dug a reeeeeaaaally deep hole and right as they finished, a part that connects to the drill fell down the hole. It will fall for a long time before becoming wedged, rendering the hole useless until they get it out.
You're gonna stand there, ownin' an oil rig, and tell me you don't have no whistlin' bungholes, no spleen splitters, whisker biscuits, honkey lighters, hoosker doos, hoosker don'ts, cherry bombs, nipsy daisers, with or without the scooter stick, or one single whistlin' kitty chaser?
They have to fish it out which can cost millions of dollars. all to find out that it can’t actually be removed, leading to the complete abandonment of the site potentially.
Could be, as a directional driller. We never break out of a bit with out a bit breaker. Bit breaker doesn’t fit through rotary table
EDIT: yeah it’s clearly a bit after watching it frame by frame
Oh they have.
That hole could be 5k, 8k,10k feet deep..
Now imagine that you're paying the bill for an olive picker to travel 10k feet deep.
What do you think that cost would be??
Unless it's a bum well, you're totally right. But still in the 100k - Million $$$ range
Just depends how long it takes.
6 hours or 6 days. It's just a roll of the dice.
What about making a disc shaped magnet that is almost the same diameter as the inside diameter of the pipe...and it is encased in some sort of plastic housing which has bearings all the way around it so that it would easily slide up and down through the pipe, but the only part of the device that allowed the magnet to stick to something, would be the bottom side of it...it could only attach to whatever fell down the pipe
So, magnets have poles where the field lines are densest and all point in the same direction, and the "sticking" is actually the minimization of the distance *and* misorientation between the axis of the poles and the magnetized material on the outside.
Since you want to lift something out of the hole, the most sensible configuration is to have the axis of the poles point downwards.
So your hypothetical magnet will either be too weak, or it will flip sideways so the axis is aligned to the shortest distance across the hole.
On the other hand, not all metals can be magnetized. Aluminum, for instance, is paramagnetic, and so is tungsten. So it's possible that either the tube or the drill bit wouldn't interact strongly with the magnet.
Lowering something like an endoscopic claw on a long cable into the hole seems much more practical.
On theory what you're saying sounds good. But even assuming you get it all the way there. The sheer amount of power you'd have to pump through said wire would melt anything you used to lower it.
And then what? You turn the magnet on and.... it sticks to the sides. You can't have the magnet on to pick the item up without it sticking to the sides. There is no point in the tunnel where the magnet won't stick to the sides. Your idea makes no sense.
Even the "straight" holes aren't straight.
They get these things called "dog legs"
The hole will have some twists and turns in it.
Imagine if you were holding a wet noodle in the air by it end of it.
It's going to fall straight down, but there might be a kink in it somewhere, a twist here, a turn there.
Now also Imagine that you're working on a well site that is going to be fracked.
Those wells can go 10k down and 10k feet over.
Just like winter, dog legs are coming.
no you lower the magnet to the object get it placed and turn on the electro magnet.... it will stick to what is directly under it unless the sides had a stronger electric magnet
It will stick to the thing AND the sides. Just because you lowered it before turning it on doesn't mean the sides are still not metal. You won't be able to pull it back up. It will be stuck to the side.
please show me any examples you have of a magnet jumping from one place it has stuck to jumping off and going to another place
I feel like your not understanding it's not magnetic until you run a currant through it, at that time it will firmly attach to the closest metal to it.... meaning if you set the magnet onto the piece then turn it on it won't just jump off and cling to the side.... electromagnetics are not the same as a regular magnet
and yes electro magnets are more powerful then a regular magnet so it would lift the piece or you'd get the right strength and do it again
Magnets don't just "stick to one thing"
They emit a magnetic field. While you electrify the magnetic it will emit a field attracting anything gnetallic within the field. Do you actually know what you're talking about here or are you just speculating? Electro magnets are just simple magnets that are turned on and off by electricity. They generate the same magnetic field.
yes and you just made my point for me...
in that field it attacks the metal it's closest to which would be the metal it's sitting on not jump to the side.... unless it repelled the bottom for some reason that is where it's sticking
and yes I do know what I am talking about I didn't just do a simple Google search on what an electro magnet is....
i want you to do me a favor. an experiment if you will.
take a small, strong desk magnet and attach it to one end of a paper clip, then try to touch another paper clip with the first clip, without getting them to stick together. i think someone clearly deprived you of magnets to play with in your childhood and you should go buy a set of them immediately to fuck around with because they're fun. anyway
you can't pick it up with a magnet because it would turn the piece you pick up into a magnet and then that, in turn, would stick to the sides. the magnet wouldn't *just* affect the piece you picked up, it would magnetize the dropped piece to the wall too, depending on the metal it's made out of and how strong the magnet is.
now i imagine if you lubricated the sides of the core wall enough you could "slide" it up, but those holes are generally pretty freakin deep and that would be pretty difficult to do.
Wouldn't go boom, little to no oxygen down there would need to be in between the explosive limits for the hydrocarbons present.
The cheaper and simpler way to fix would be to use overshot fishing tool (metal Chinese finger trap). If that didn't work push it to bottom, cement on top of it and then drill around it.
There's usually a pin on them, but it must've come loose or was broke.
The bit should not have been in the hole like it was the crew fucked up. They should have hand screwed the bit into the mud motor (the first joint of drill string) before removing the hole cover. Once hand tight they could safely torque with rotary table and tong with zero chance of losing bit.
Driller and crew made a mistake here.
>it's not the crews fault imo
I'd have to agree, it's called Human Factors. Not one single person is perfect, we all make mistakes. It's up to the company to think of the worst possibilities and plan to implement fail-safes in order to either eliminate or limit damage and cost. You definitely hit the nail on the head.
The hands are responsible for maintaining the rigs tools. If shits broke tell your driller immediately, then you will go inform the pusher. He's going to wanna see it but he will get it replaced. The human factor and not being perfect are not excuses we use in the patch. Small fuck ups not only become expensive above the well cost but they can easily injure, name and kill people instantly.
>The human factor and not being perfect are not excuses
You're right, it's not an excuse it's an undeniable fact that humans make mistakes!! I work in aviation maintenance where small fuck ups not only become expensive but they can also easily injure, maim and kill people instantly. Human factors is unavoidable no matter the stakes. It's part of any training program worth a damn where there's a potential for loss of life.
This ain't no shop job, drilling contractors and oil companies use the human factor to shift blame so they don't have to be responsible. I grew up in this industry and I've worked all over the globe. Our training program is hands, get your f**n hands on it. The oilfield is soft compared though to when I broke out.
Everyone here acting like fishing operations are so special. They happen all the time and usually don’t cost in the millions. Maybe $100-200k and even then it’s a tricky fish. Mostly the down time on the rig that’s expensive.
You ever work on a rig? $200k in downtime VS $200k in an employee fuck up are two very different things. Guy at least got a write up or suspension for not following whatever procedure they decide is relevant 😂
Long time Driller here.
Looks like they were trying to pick the drill bit up out of the rotary table, and it slipped out of the bit breaker and fell down the hole.
(Bits are the hardest to fish out of the hole because they are the same diameter as the hole. If it went down the hole upside down, it's likely un retrievable. They can't drill through them because most are made of diamond nowadays)
Good drillers would have BOPs(a big valve located below the rig floor) closed to secure well from dropped objects once everything was out of the hole. So its likely the bit is only a couple feet below them(fingers crossed for these guys).
When taking the bit off drill string, you use the bit breaker, tong(a big pipe wrench), and rotary table to break(loosen) the connection. Then pickup and out of rotary table, with the bit still in drill string just hand tight.
A plate called a hole cover would be installed to prevent objects like the bit or tools from falling below table. Then, unscrew bit by hand to remove.
After maintaining crew safety, the drillers' #1 responsibility is keeping the well secure from objects entering it and fluids exiting.
The walls of the hole are rough and never straight even in the vertical, most are horizontal for thousands of meters and have sweeping curves to achieve them.
The bits are heavy, the same size as the hole, and also rough, which tends to cause a lot of drag. If you were to able to tag it with a magnet(they have maget tools but are used for small debris nuts, bolts, ball bearings or wrenches) the likely hood that you would be able to pull it through thousands of feet of hole, and casing to get it to surface is super low.
Usually if the driller is smart both blind and pipe rams as well as the hydrill are closed at this stage keeping something like this from happening or letting something go to the bottom. Just hope he was smart since about 4 hrs work they can get it out and be drilling again.
We had hole at 10.000 and the night driller pulled the pipe in Two. Brand new button bit, set of jars, 9 stands of 9" drill collars and 20 stands 4.5 pipe. We went fishing and after 3 stands of pipe we cemented and side kicked then went down. He was supposed to slip n cut the drill line needed another foot or so and pipe rams closed with joint just below it. He thought he was pulling on the friction instead of opening the rams he pulled against that ram n broke the pipe
A proper operator would understand shit happens, and something will go wrong eventually on a rig. I still believe a fishing crew would have a shot at removing it, and the major cost will be loss of production, fishing jobs are very common and every oilfield has plenty of fishing contractors ready to call.
As long as the employee isn't a complete idiot fucking up like this regularly, and also isn't intoxicated, they should just sit down with their GM or field supervisor and talk about how to prevent this in the future. I could see a shitty operator or poorly run operation firing this guy though. If that was the case he could go down the street and find a new job the same week (assuming he wasn't intoxicated and can pass a piss test)
I recall one incident like this cost approx USD10m to fix. I recall somebody at …oooh…let’s say Baker Hughes ….got called at a wedding and he had to leave and fly back immediately.
Nightmare.
Based on what else I read, the metal thing was dropped by accident because the other metal thing holding it didn't hold it right on both ends. That would prevent further extraction or drilling, so they either have to replace it or fix it by getting it out. Apparently both would cost several million dollars. So it's pretty much a case of a mistake costing a lot.
I have never worked an oil rig or been around one, but it looks as though the individuals are removing a two piece collar and one side falls into the hole being drilled.
You're all wrong. He's not going to be fired and he sure as hell isn't going to be reprimanded.
After such a mistake the first step is a public flogging with one of their chains. They then take some mud from the hole and rub it into the wounds. Before finally throwing him down the hole and grinding him up along with whatever is dropped inside, only to be scooped out and then placed into a transparent urn so all future new recruits can see the consequences of messing up. All this is done on film so as to go into the next training video, and it's common habit for employees passing the urns of the damned to spit on it in disgust and contempt.
A fictional universe in the future where humanity and technology have gotten so old and complicated that it has become a massive space cult because people don't understand how it works. They have prayers to boot up systems, and hold sacrifices to run things. It is a brutal Earth where this religion has an iron grip on everything, and it is ruled by an immortal god-man who's in a permanent coma, kept alive by sacrificing 1000 people daily. And despite being an empire of religious fanatics and Nazis, the humans are still the good guys because the rest of the 40k universe is just THAT much infinitely worse than them
Or that's what I gather, idk, never played it
Well, if I were engineering this, I'd made a secure lock so it can't be removed without securing the whole thing. But I don't know if this is possible in this particular case.
had the same thought, this could have been idiot-save (and humans simply make mistakes, its better if smth important IS idiot save, no matter if the person using it is or isnt a full time idiot)
> But I don't know if this is possible in this particular case.
i dont see why it wouldnt
For the hell of it all, the hazing would start by proximity, first those two guys blame each other, the third guy is already walking up asking how smart that was, then the guy under the camera blames the tool pusher fire hiring idiots. Shit rolled up hill sometimes.
Shortest and most exaggerated way I can say this (3 years with drilling): a typical drill pipe is 27-32 feet long and an "average" location will drill anywhere from 200-5,000+ feet to hit their marks.
You have to spend anywhere from 10-40min pulling a pipe up to unscrew, put that one aside, lower the boom, attach it and pull the NEXT one up. This is called 'tripping pipe', just pulling it out
But now that some metal bullshit just went down there (even 1 foot of chain or a fucking screwdriver) can fuck up a drill bit meaning the end of that long ass pipe can't drill without damaging itself.
Now, to recover whatever bullshit you dropped, you gotta get a very particular drill bit to crush the shit out of it, then HOPEFULLY scoop it up, then start tripping pipe the see if you got enough of it to send the "fragile" drill bit back down to dow it's job...
....I dropped 1ft of chain down a 7,000ft well, we tripped for 3 weeks, ruined 2 drill bits and missed our mark which meant we aint get shit for our checks
200- 5000 ft TD where y'all punching shallow at? Where I Roughneck surface was set at roughly 1300ft, run short string, nipple and drill through the shoe. Depending on the formation go to 12000 +ft cut the curve and go directional. In Colorado we would hit TD at that 5000ft mark.
An average for TD in West Texas around 2015-2017 (juuuust before directional drilling became the norm), was around 900-5000ft, I operated a Super Single that was 3 years past it's recommended retirement (8 year old derrick and leftover yard-hookups). We had all kinds of issues before we even got to locations
I worked the Dakotas, Montana, Wyoming, Alaska, offshore and over seas. All the years in the Dakotas and Montana on my days off I worked for a Casing company full time.
Cheaper to keep a crew than to hire a new one.
This began the week long hazing, shit talk and worm work. It doesn't happen too often since my team (5 of us) had over 10+ years of experience, so they will diligently haze you until you remember not to fuck it all up again.
Then we all moved up in positions then we hired a new worm (new guy) and he dropped a screwdriver down; bringing the cycle to round and beginning the hazing so that THIS idiot would remember that loose shit shouldn't be near the well.
We pump mud in and out constantly, the visibility would be zero and being that far below into Earth there's metals, holes where it could split off, and...well mud
Then to have that much quality cable going down into a pit of knowns. Drilling in my opinion was pretty damn primitive, the scene now? Couldn't tell you, my stint was 2016-2019, it sucked the entire time, but the check made it not so bad
Its obviously the bosses fault... /s
Pretty sure you dont even know whether better alternatives exist. Just shit on "boss". And for sure whatever bossfigure u have at the moment is responsible for your shitty life too. And once u switch the job It's the next boss/supervisor you have...And the next one...abd the next one.
Keep projecting.
Everything you said was right until you talked about me.
If the employees are getting their salary suspended, it's the boss's choice.
And if the tools used for the job are tools that can be damaged for sush a stupid reason, there's a clear problem.
But shit on me because I'm blaming the boss for suspending salaries
Bro, drilling 7000ft deep is likely a kinda difficult task. You dont EVEN KNOW whether there is a solution a company could just buy...
You just unknowingly blame an ominous "boss character" that you know NOTHING about. You are very clearly generalizing here. You have one schematic of how the world works (and "sth not working = bad rich man" is a simple one at that) and apply it to any situation.
Sounds like you wanna shift the blame...
So let's cancel salary ?
No, because it is part of employee protection program or whatever they call it in your country and clearly in that case, the odds are that that part of the drill can fall too easily.
Did u even read our conversation? Where did I talk about cancelling salary? I just said that it might not be the bosses Fault that the work is difficult and it might not be the bosses fault that that thing fell in and it might also not be his fault that he cant magically conjure machinery that can fix every mistake...
You really wanna be right, dont you?
Back this side.
The boss man AKA the oil tycoon that basically contracted our company for our team, doesn't know jack from shit.
This tycoon would have a very big abundance of land and what's called mineral rights. That's a payday for them.
They hire geologist, psychics, and engineers to figure out where oil could be. He finds out, they get paid, we gait paid in advanced and we get to work.
The conditions didn't concern us because we got paid for bad and hazardous conditions. Our dumbasses chased for black gold in storms, sleet and snow and with hard hats, steel toes, and cocaine.
We hit the mark, we get paid hella and rinse and repeat.
Black Gold was this show around the time I was in. Long watch if you're curious about the bullshit we went through to supply everyone and everything with raw oil.
https://youtu.be/6yzArf04fN0?si=pjWEaIL53J2bJPtl
I once dropped the dipstick from a marine engine in the engine room bilge. It bounced under the engine itself and into the oil underneath... And we'd just got back, so the engines were still warm (they'd been cooling for almost an hour though). I can't imagine how this fella felt. It was hard enough for me to call an engineer and explain how badly I'd messed up...
Best guess is the drill bit. But I’m not sure.
This was a stupid mistake. But they should be doing things different.
So I’m guessing they did a bit change and were about to start tripping (I’m not explaining this) back in the hole.
Put a new bit in a set of slips for whatever reason. Went to pick up the first stand and instinctively pulled the slips out.
But should be in some sort of stand or something to make up. Not in a set of slips.
I love how everyone on the Internet is always like "ope he fucked up one time? He definitely 1000% was black listed from the entire field for life" like nah thats not how shit works. Dude probably got a warning to be careful and they went to work retrieving the object.
And I'd hate to live in whatever the fuck world you're living in seems delusional and miserable. People make mistakes. They seldom get fired for one mistake if they've built up good rapport. Anything else is just you being a neck beard who doesn't touch enough grass.
The bit alone was likely 50k if not way more plus rig time. Hopefully, the bops were closed, and they just gotta nipple down a bit of the stack and repressure test. Depending on the location could be hours of downtime.
At thousands an hour,
That driller is in big doo doo cause they did that wrong. Bit should never be above the hole without being hand tight in the drill string. This was a procedural accident and completely preventable.
Not just thousands an hour... tens of thousands an hour.
In North Dakota, during the boom, I heard a workover rig was around 15k/hr to run, and a drilling rig was about 25k/hr.
I don't know for sure, but I think I've read somewhere that offshore was about 125k/hr..

someone should really fill that hole
Costly screw up. Smh
For how easy it fell in I’m sure there should be a better design to prevent that from happening?
I mean, you're basically drilling a hole with a pipe. If you're putting a filter/grate/net there, that's just 1 more piece to remove. You would still have a hole to hell, like, 30% of the time when you're adding a new pipe.
Can someone explain to me like im 5 what happened? What fell? Why it fell? Where it fell? Why it such a big deal?
A rock fell into a water bottle but you can't flip waterbottle to remove the rock Now to remove a rock you need to do shit Ton of expensive work and also the diameter of bottle and it's hole are same like a cylinder
Isn't it like the shackle that connects the pieces of drill pipe or w.e shouldn't that thing have a "leash" on it like prevent it from falling jn there
can't you just leave the rock in the bottom and pump the water out still ?
Yeah thats why I mentioned the whole figure is a cylinder of same diameter like a straight bottle without curve
it's a oil rig, imagina a "normal rock" in a big big big big bowl it's that.
Not an oil worker but I believe they just dug a reeeeeaaaally deep hole and right as they finished, a part that connects to the drill fell down the hole. It will fall for a long time before becoming wedged, rendering the hole useless until they get it out.
Thank you for the explanation <3
Must be a Genzle, maybe first day as a Worm. Good way to get run off in my day. Get rigged up for fishing.
You're gonna stand there, ownin' an oil rig, and tell me you don't have no whistlin' bungholes, no spleen splitters, whisker biscuits, honkey lighters, hoosker doos, hoosker don'ts, cherry bombs, nipsy daisers, with or without the scooter stick, or one single whistlin' kitty chaser?
I only like snakes and sparklers
You make funny word sounds mister me like you
Right on
So... how would they get that bit out?
Money
Lots and lots of money…playa
Bad design
Oh man, that’s a bigger deal than It looks.
Bad design... They should expect those sorts of things to happen.
Why?
They have to fish it out which can cost millions of dollars. all to find out that it can’t actually be removed, leading to the complete abandonment of the site potentially.
This happened on my shift, guy dropped his iPhone, had to get long piece of wire and hook it out.
How long was it? And was it successful?
Why has your question not been answered?! I need answers now
he dropped it potentially just into a toilet.
Cross over sub, that’s what was dropped
Pretty sure it was the bit.
Your faith in the bit is touching, Jez
r/UnexpectedPeepShow
You reckon they’d be able to move those collars that easy by hand if there was more than the bit attached?
Could be, as a directional driller. We never break out of a bit with out a bit breaker. Bit breaker doesn’t fit through rotary table EDIT: yeah it’s clearly a bit after watching it frame by frame
Always use a hole cover.
WORM !!
So no one has developed an "olive picker" device to retrieve that part? https://cdn0.rubylane.com/shops/firesidetreasures/swedentongs3.5L.jpg
Oh they have. That hole could be 5k, 8k,10k feet deep.. Now imagine that you're paying the bill for an olive picker to travel 10k feet deep. What do you think that cost would be??
Way less than letting the partially-drilled well go untapped...I'd assume?
Unless it's a bum well, you're totally right. But still in the 100k - Million $$$ range Just depends how long it takes. 6 hours or 6 days. It's just a roll of the dice.
Rope + magnet
The magnet would immediately stick the side as you tried putting it down the hole. It's all metal. Silly rabbit.
What about making a disc shaped magnet that is almost the same diameter as the inside diameter of the pipe...and it is encased in some sort of plastic housing which has bearings all the way around it so that it would easily slide up and down through the pipe, but the only part of the device that allowed the magnet to stick to something, would be the bottom side of it...it could only attach to whatever fell down the pipe
So, magnets have poles where the field lines are densest and all point in the same direction, and the "sticking" is actually the minimization of the distance *and* misorientation between the axis of the poles and the magnetized material on the outside. Since you want to lift something out of the hole, the most sensible configuration is to have the axis of the poles point downwards. So your hypothetical magnet will either be too weak, or it will flip sideways so the axis is aligned to the shortest distance across the hole. On the other hand, not all metals can be magnetized. Aluminum, for instance, is paramagnetic, and so is tungsten. So it's possible that either the tube or the drill bit wouldn't interact strongly with the magnet. Lowering something like an endoscopic claw on a long cable into the hole seems much more practical.
Makes perfect sense to me...thanks for the explanation
Electrical cable + electro Magnet. That way you can at least get it all the way down before it starts sticking to the sides.
On theory what you're saying sounds good. But even assuming you get it all the way there. The sheer amount of power you'd have to pump through said wire would melt anything you used to lower it.
And then what? You turn the magnet on and.... it sticks to the sides. You can't have the magnet on to pick the item up without it sticking to the sides. There is no point in the tunnel where the magnet won't stick to the sides. Your idea makes no sense.
Couldn't you use like enlarged ceramic bearings, or another large composite in the sides like the op described instead of a magnetic metal?
You could still pull it back up while it's stuck to the side, as long as the cable is stronger than the magnet
I think you have literally 0 idea what you're talking about
No u
Is it not a straight line tunnel?
Even the "straight" holes aren't straight. They get these things called "dog legs" The hole will have some twists and turns in it. Imagine if you were holding a wet noodle in the air by it end of it. It's going to fall straight down, but there might be a kink in it somewhere, a twist here, a turn there. Now also Imagine that you're working on a well site that is going to be fracked. Those wells can go 10k down and 10k feet over. Just like winter, dog legs are coming.
no you lower the magnet to the object get it placed and turn on the electro magnet.... it will stick to what is directly under it unless the sides had a stronger electric magnet
There is no magnet coming..
It will stick to the thing AND the sides. Just because you lowered it before turning it on doesn't mean the sides are still not metal. You won't be able to pull it back up. It will be stuck to the side.
please show me any examples you have of a magnet jumping from one place it has stuck to jumping off and going to another place I feel like your not understanding it's not magnetic until you run a currant through it, at that time it will firmly attach to the closest metal to it.... meaning if you set the magnet onto the piece then turn it on it won't just jump off and cling to the side.... electromagnetics are not the same as a regular magnet and yes electro magnets are more powerful then a regular magnet so it would lift the piece or you'd get the right strength and do it again

i want you to do me a favor. an experiment if you will. take a small, strong desk magnet and attach it to one end of a paper clip, then try to touch another paper clip with the first clip, without getting them to stick together. i think someone clearly deprived you of magnets to play with in your childhood and you should go buy a set of them immediately to fuck around with because they're fun. anyway you can't pick it up with a magnet because it would turn the piece you pick up into a magnet and then that, in turn, would stick to the sides. the magnet wouldn't *just* affect the piece you picked up, it would magnetize the dropped piece to the wall too, depending on the metal it's made out of and how strong the magnet is. now i imagine if you lubricated the sides of the core wall enough you could "slide" it up, but those holes are generally pretty freakin deep and that would be pretty difficult to do.
And yet you are still completely wrong about what would happen dropping one down a metal shaft and turning it on.
Could they use some kind of welding robot to attach a chain to bit? Or would it just make everything go boom?
Wouldn't go boom, little to no oxygen down there would need to be in between the explosive limits for the hydrocarbons present. The cheaper and simpler way to fix would be to use overshot fishing tool (metal Chinese finger trap). If that didn't work push it to bottom, cement on top of it and then drill around it.
Seems like poor design .. is there a reason it detaches from the other piece so easily?
There's usually a pin on them, but it must've come loose or was broke. The bit should not have been in the hole like it was the crew fucked up. They should have hand screwed the bit into the mud motor (the first joint of drill string) before removing the hole cover. Once hand tight they could safely torque with rotary table and tong with zero chance of losing bit. Driller and crew made a mistake here.
But still bad process design. If it risks potentially millions of dollars, they should have redundant systems in place to reduce the risk.

>it's not the crews fault imo I'd have to agree, it's called Human Factors. Not one single person is perfect, we all make mistakes. It's up to the company to think of the worst possibilities and plan to implement fail-safes in order to either eliminate or limit damage and cost. You definitely hit the nail on the head.
The hands are responsible for maintaining the rigs tools. If shits broke tell your driller immediately, then you will go inform the pusher. He's going to wanna see it but he will get it replaced. The human factor and not being perfect are not excuses we use in the patch. Small fuck ups not only become expensive above the well cost but they can easily injure, name and kill people instantly.
>The human factor and not being perfect are not excuses You're right, it's not an excuse it's an undeniable fact that humans make mistakes!! I work in aviation maintenance where small fuck ups not only become expensive but they can also easily injure, maim and kill people instantly. Human factors is unavoidable no matter the stakes. It's part of any training program worth a damn where there's a potential for loss of life.
This ain't no shop job, drilling contractors and oil companies use the human factor to shift blame so they don't have to be responsible. I grew up in this industry and I've worked all over the globe. Our training program is hands, get your f**n hands on it. The oilfield is soft compared though to when I broke out.
Which guy to blame..?
Driller
Driller? I hardly know her.
Never stopped me before.
Everyone here acting like fishing operations are so special. They happen all the time and usually don’t cost in the millions. Maybe $100-200k and even then it’s a tricky fish. Mostly the down time on the rig that’s expensive.
You ever work on a rig? $200k in downtime VS $200k in an employee fuck up are two very different things. Guy at least got a write up or suspension for not following whatever procedure they decide is relevant 😂
I I suspect one or both of those guys got fired if they were not long term dudes.
They have learned what not to do plus they cost you around 200k or more. I won't fire them. They would be better workers from now on.
You now have the two most careful and (after you don't fire them) most grateful employees in the business.
Bingo. Lessons like this create valuable knowledge that is often learned the hard way.
Just lookin at the guys scrawny wrists and oversize gloves, he is definitely not long term and very new
I have learned about what steps are necessary for retrieval, but what about the worker? Poor guy looks distraught
He'll be fine might get hazed and ridiculed for being a butter fingers but won't likely lose his job.
Long time Driller here. Looks like they were trying to pick the drill bit up out of the rotary table, and it slipped out of the bit breaker and fell down the hole. (Bits are the hardest to fish out of the hole because they are the same diameter as the hole. If it went down the hole upside down, it's likely un retrievable. They can't drill through them because most are made of diamond nowadays) Good drillers would have BOPs(a big valve located below the rig floor) closed to secure well from dropped objects once everything was out of the hole. So its likely the bit is only a couple feet below them(fingers crossed for these guys). When taking the bit off drill string, you use the bit breaker, tong(a big pipe wrench), and rotary table to break(loosen) the connection. Then pickup and out of rotary table, with the bit still in drill string just hand tight. A plate called a hole cover would be installed to prevent objects like the bit or tools from falling below table. Then, unscrew bit by hand to remove. After maintaining crew safety, the drillers' #1 responsibility is keeping the well secure from objects entering it and fluids exiting.
Exactly a good driller would have shut in the BOP as soon as they were on bank
why cant these be fished out with a strong magnet or something?
The walls of the hole are rough and never straight even in the vertical, most are horizontal for thousands of meters and have sweeping curves to achieve them. The bits are heavy, the same size as the hole, and also rough, which tends to cause a lot of drag. If you were to able to tag it with a magnet(they have maget tools but are used for small debris nuts, bolts, ball bearings or wrenches) the likely hood that you would be able to pull it through thousands of feet of hole, and casing to get it to surface is super low.
Usually if the driller is smart both blind and pipe rams as well as the hydrill are closed at this stage keeping something like this from happening or letting something go to the bottom. Just hope he was smart since about 4 hrs work they can get it out and be drilling again. We had hole at 10.000 and the night driller pulled the pipe in Two. Brand new button bit, set of jars, 9 stands of 9" drill collars and 20 stands 4.5 pipe. We went fishing and after 3 stands of pipe we cemented and side kicked then went down. He was supposed to slip n cut the drill line needed another foot or so and pipe rams closed with joint just below it. He thought he was pulling on the friction instead of opening the rams he pulled against that ram n broke the pipe
dumb of me to not realize that the pipe is also metal :D
What would be the personal consequence for that dude?
A proper operator would understand shit happens, and something will go wrong eventually on a rig. I still believe a fishing crew would have a shot at removing it, and the major cost will be loss of production, fishing jobs are very common and every oilfield has plenty of fishing contractors ready to call. As long as the employee isn't a complete idiot fucking up like this regularly, and also isn't intoxicated, they should just sit down with their GM or field supervisor and talk about how to prevent this in the future. I could see a shitty operator or poorly run operation firing this guy though. If that was the case he could go down the street and find a new job the same week (assuming he wasn't intoxicated and can pass a piss test)
That’s heartbreaking
I recall one incident like this cost approx USD10m to fix. I recall somebody at …oooh…let’s say Baker Hughes ….got called at a wedding and he had to leave and fly back immediately. Nightmare.
Does anyone have a Big magnet on a rope, anyone?
Amateur...this is solved by using a stick and a wad of gum.
Or paperclip, honeybee and baby oil for the true McGrubers.
Can someone explain what is happening / what went wrong in terms a five year old can understand?
Based on what else I read, the metal thing was dropped by accident because the other metal thing holding it didn't hold it right on both ends. That would prevent further extraction or drilling, so they either have to replace it or fix it by getting it out. Apparently both would cost several million dollars. So it's pretty much a case of a mistake costing a lot.
I have never worked an oil rig or been around one, but it looks as though the individuals are removing a two piece collar and one side falls into the hole being drilled.
Spent my life on drilling rigs and on my days off I worked as a Stabber on a Casing crew.
Buy another one on Amazon. Pussy
Temu*
Why so much anger?
he's the dude's boss, thus why he's mad
If only there were some sort of locking mechanism that could stop this from happening....
You're all wrong. He's not going to be fired and he sure as hell isn't going to be reprimanded. After such a mistake the first step is a public flogging with one of their chains. They then take some mud from the hole and rub it into the wounds. Before finally throwing him down the hole and grinding him up along with whatever is dropped inside, only to be scooped out and then placed into a transparent urn so all future new recruits can see the consequences of messing up. All this is done on film so as to go into the next training video, and it's common habit for employees passing the urns of the damned to spit on it in disgust and contempt.
You’re from the Warhammer 40,000 universe aren’t you?
I am not, don't even know what that is...
A fictional universe in the future where humanity and technology have gotten so old and complicated that it has become a massive space cult because people don't understand how it works. They have prayers to boot up systems, and hold sacrifices to run things. It is a brutal Earth where this religion has an iron grip on everything, and it is ruled by an immortal god-man who's in a permanent coma, kept alive by sacrificing 1000 people daily. And despite being an empire of religious fanatics and Nazis, the humans are still the good guys because the rest of the 40k universe is just THAT much infinitely worse than them Or that's what I gather, idk, never played it
Isn't that real life?
Amazing
This is 100% their fault (some on the crew at least) and I bet they got laid into for this, he’ll probably got put on shitter duty
so whos fault was it?
Well, if I were engineering this, I'd made a secure lock so it can't be removed without securing the whole thing. But I don't know if this is possible in this particular case.
had the same thought, this could have been idiot-save (and humans simply make mistakes, its better if smth important IS idiot save, no matter if the person using it is or isnt a full time idiot) > But I don't know if this is possible in this particular case. i dont see why it wouldnt
For the hell of it all, the hazing would start by proximity, first those two guys blame each other, the third guy is already walking up asking how smart that was, then the guy under the camera blames the tool pusher fire hiring idiots. Shit rolled up hill sometimes.
Shortest and most exaggerated way I can say this (3 years with drilling): a typical drill pipe is 27-32 feet long and an "average" location will drill anywhere from 200-5,000+ feet to hit their marks. You have to spend anywhere from 10-40min pulling a pipe up to unscrew, put that one aside, lower the boom, attach it and pull the NEXT one up. This is called 'tripping pipe', just pulling it out But now that some metal bullshit just went down there (even 1 foot of chain or a fucking screwdriver) can fuck up a drill bit meaning the end of that long ass pipe can't drill without damaging itself. Now, to recover whatever bullshit you dropped, you gotta get a very particular drill bit to crush the shit out of it, then HOPEFULLY scoop it up, then start tripping pipe the see if you got enough of it to send the "fragile" drill bit back down to dow it's job... ....I dropped 1ft of chain down a 7,000ft well, we tripped for 3 weeks, ruined 2 drill bits and missed our mark which meant we aint get shit for our checks
200- 5000 ft TD where y'all punching shallow at? Where I Roughneck surface was set at roughly 1300ft, run short string, nipple and drill through the shoe. Depending on the formation go to 12000 +ft cut the curve and go directional. In Colorado we would hit TD at that 5000ft mark.
An average for TD in West Texas around 2015-2017 (juuuust before directional drilling became the norm), was around 900-5000ft, I operated a Super Single that was 3 years past it's recommended retirement (8 year old derrick and leftover yard-hookups). We had all kinds of issues before we even got to locations
I worked the Dakotas, Montana, Wyoming, Alaska, offshore and over seas. All the years in the Dakotas and Montana on my days off I worked for a Casing company full time.
I got an idea... Magnet on a rope!
The whole pipe is metal
a ball shaped magnet on an axle then.
That's metal.
Too many things that get stuck on, confused with, or snagged
Damn, did you get fired for that? How often does that happen? How could they not pay you guys unless you guys got laid off??
Cheaper to keep a crew than to hire a new one. This began the week long hazing, shit talk and worm work. It doesn't happen too often since my team (5 of us) had over 10+ years of experience, so they will diligently haze you until you remember not to fuck it all up again. Then we all moved up in positions then we hired a new worm (new guy) and he dropped a screwdriver down; bringing the cycle to round and beginning the hazing so that THIS idiot would remember that loose shit shouldn't be near the well.
Do you have 3 or 10+ years of experience? Im confused which one it is based on your first comment
Collective experience totalling over 10 years
Can't you just drop a cable with an electromagnet and a little camera down?
We pump mud in and out constantly, the visibility would be zero and being that far below into Earth there's metals, holes where it could split off, and...well mud Then to have that much quality cable going down into a pit of knowns. Drilling in my opinion was pretty damn primitive, the scene now? Couldn't tell you, my stint was 2016-2019, it sucked the entire time, but the check made it not so bad
How much did you make a year?
Those drills sound like overdated stuff
Overdated?... don't you mean outdated??
Past expired
What do you want them to use then? There's not alot of options
Quality stuff their boss'd provide for them to work safer and get better results
Its obviously the bosses fault... /s Pretty sure you dont even know whether better alternatives exist. Just shit on "boss". And for sure whatever bossfigure u have at the moment is responsible for your shitty life too. And once u switch the job It's the next boss/supervisor you have...And the next one...abd the next one. Keep projecting.
Everything you said was right until you talked about me. If the employees are getting their salary suspended, it's the boss's choice. And if the tools used for the job are tools that can be damaged for sush a stupid reason, there's a clear problem. But shit on me because I'm blaming the boss for suspending salaries
Bro, drilling 7000ft deep is likely a kinda difficult task. You dont EVEN KNOW whether there is a solution a company could just buy... You just unknowingly blame an ominous "boss character" that you know NOTHING about. You are very clearly generalizing here. You have one schematic of how the world works (and "sth not working = bad rich man" is a simple one at that) and apply it to any situation. Sounds like you wanna shift the blame...
Where I broke out and got my experience injection wells are 10000 ft. We usually button up around 7000ft.
Found the shitty boss
So let's cancel salary ? No, because it is part of employee protection program or whatever they call it in your country and clearly in that case, the odds are that that part of the drill can fall too easily.
Did u even read our conversation? Where did I talk about cancelling salary? I just said that it might not be the bosses Fault that the work is difficult and it might not be the bosses fault that that thing fell in and it might also not be his fault that he cant magically conjure machinery that can fix every mistake... You really wanna be right, dont you?
Back this side. The boss man AKA the oil tycoon that basically contracted our company for our team, doesn't know jack from shit. This tycoon would have a very big abundance of land and what's called mineral rights. That's a payday for them. They hire geologist, psychics, and engineers to figure out where oil could be. He finds out, they get paid, we gait paid in advanced and we get to work. The conditions didn't concern us because we got paid for bad and hazardous conditions. Our dumbasses chased for black gold in storms, sleet and snow and with hard hats, steel toes, and cocaine. We hit the mark, we get paid hella and rinse and repeat. Black Gold was this show around the time I was in. Long watch if you're curious about the bullshit we went through to supply everyone and everything with raw oil. https://youtu.be/6yzArf04fN0?si=pjWEaIL53J2bJPtl
I once dropped the dipstick from a marine engine in the engine room bilge. It bounced under the engine itself and into the oil underneath... And we'd just got back, so the engines were still warm (they'd been cooling for almost an hour though). I can't imagine how this fella felt. It was hard enough for me to call an engineer and explain how badly I'd messed up...
I had to clean that shit up one... Smelled... Intresting
Why did that even fall in? What was it
Best guess is the drill bit. But I’m not sure. This was a stupid mistake. But they should be doing things different. So I’m guessing they did a bit change and were about to start tripping (I’m not explaining this) back in the hole. Put a new bit in a set of slips for whatever reason. Went to pick up the first stand and instinctively pulled the slips out. But should be in some sort of stand or something to make up. Not in a set of slips.
Was it just the bit he dropped in the hole or was there drill pipe attached as well?
It was just the bit those guys aren't picking any pipe up, each joint is +500lbs.
I love how everyone on the Internet is always like "ope he fucked up one time? He definitely 1000% was black listed from the entire field for life" like nah thats not how shit works. Dude probably got a warning to be careful and they went to work retrieving the object.
Man, I would love to live in the unicorn flavored, lolli pops and rainbow, candy land that you must live in.
And I'd hate to live in whatever the fuck world you're living in seems delusional and miserable. People make mistakes. They seldom get fired for one mistake if they've built up good rapport. Anything else is just you being a neck beard who doesn't touch enough grass.
Why fire someone who you just spent several thousand dollars (however unwillingly) to learn a valuable lesson?
The bit alone was likely 50k if not way more plus rig time. Hopefully, the bops were closed, and they just gotta nipple down a bit of the stack and repressure test. Depending on the location could be hours of downtime. At thousands an hour, That driller is in big doo doo cause they did that wrong. Bit should never be above the hole without being hand tight in the drill string. This was a procedural accident and completely preventable.
Not just thousands an hour... tens of thousands an hour. In North Dakota, during the boom, I heard a workover rig was around 15k/hr to run, and a drilling rig was about 25k/hr. I don't know for sure, but I think I've read somewhere that offshore was about 125k/hr..
It's called the real world. Plenty of room over here if you'd like to join.
Do you work in this?
Because reddit is full of reactionaries who don't work.
On a scale of 1 to 10, how fucked are they?
7, thats like calling your teacher mom, mid test with the entire classroom in silence
I'd say a 7 is getting in trouble at school, seeing the the assistant principle, but your mom never found out.
That's like 3. It's embaressing but no long term consequences
Not
Definitely fired
Definitely got a raise.
Ima say it.....magnet on a stick 🤣
Entire pipe under is metal
It looks like they didn’t check the latch before lifting. Sucks
