That's funny, I just clicked the bell button right before reading your comment and it's my first and only channel that I clicked the bell button as well. These videos are just so damn interesting, unfortunately the only way for another video to come out is for a explosion, or death, or community emergency to happen for the CSB to launch an investigation so my relationship with the CSB channel is a little at odds.
Meh, their analysis is not always complete or accurate. Most times it is very good. However without a complete overview you can not accurately describe the root cause(s) of an accident. Many times its multiple failures. In this case Patterson screwed up multiple times it sounds like and the last failure was kill the well in time with the BOP. Crewman are hesitant to activate the ram shears as it will cause a lot of down time. This can cause the loss of hundreds of thousands even millions of dollars... and the worker's job if he makes a bad call. Work stop authority is something of a joke down here... in the end at the root cause analysis, the company will always try to blame the worker(s). The workers know that. This is especially true of lower level workers ie worms. It was a worm that could have closed the BOP but waited for authorization with deadly results. Poor training and ineptness may have also lead to his poor decision. Time is money, tens of thousands per hour of down time. This means there's a lot of pressure of those in charge to hurry. They can lose their bonus as well for needless delays so cutting corners is common here. Sure you have work stop authority, but you have no control over the poor decisions of superiors and you aren't psychic; I can't predict the future with unknown variables, can you?
@@blackhawkorg I have a different perspective on the CSB reports. They are extremely accurate in their findings. The full report is available www.csb.gov for reading.

if you do not find each and every one of these fascinating i don't understand what is wrong with you. these are not just incredibly fascinating but so very necessary to prevent future blowout accident at any kind of drilling point we have on this planet. from the rainforest in brazil to the oil fields in oman and up in the north sea and in siberia, we drill everywhere and conditions are different everywhere, so sadly no status of "fully accident proof" can exist at this point in time, and whenever humans claimed one existed it was proven wrong. anyway, great content! best wishes from germany

I work for an oil company (not involved in any way with this video) and I support them in IT. I work diligently with what I do to ensure maximum safety. Even though I’m comfortably away in an office, if a mistake is made lives are truly at risk.

@@ArcFixer What about if communications between the BOP and rig are lost? Wouldn't there be a safeguard for that?

Or is there more going on there? I know nothing about Oil or Gas drilling.
You can only control a well with BHA and pipe inserted into the well. If you’re not in the hole, you can’t pump against the pressure. A BOP cannot handle the pressure if too much, by itself
This is great work! Keep it up. USCSB videos are like my version of ASMR, but I also learn stuff. Glad to see the animation skills really maturing, too.
Odd. Kicks that blow mud out of the hole are not common, but they do happen and anyone who has been around a drilling rig for many years has seen them. Obviously the Company Man, Push and Driller would be on the ball considering how much flow they had leading up to the event. Why didn't they close the rams when the well kicked?
In this video, it looks like no mistakes were made. We’ll see what the full investigation brings. Either way, this highlights the extreme danger that working on oil wells brings. Respect to the oilers.
why is there no automatic system that closes the ram when a certain amount of mud is gained? A similar problem occurred with Deep Water Horizon, how is this not a thing yet?
Deep Water Horizon didn't pump enough or removed too much of the mud that was needed to counterbalance the oil pressure. I don't remember all the particulars but I do remember that much. The well had went through a series of kicks caused by high pressure gas zones. The BP operator was anxious to close the operation and took some extremely dangerous shortcuts that didn't work they way he hoped they would. BP is such a poorly run corporation that they had to rely on ExxonMobil and I think Texaco to help them come up with a plan to plug the blowout. I think they relied on the one engineer at the platform to make all the decisions without any oversite. The drilling engineer should be required to ask permission from the home office for the steps s/he is proposing to take like a fighter pilot does when they reach a potential target. The fact that BP is still in business is proof enough to me that they weren't fined enough.
I don't work with any heavy equipment but I absolutely love these videos very bingeable the guys voice is so calming and it really is extremely interesting
The problem here is the ocean and land based drill operations use the same type blowout prevention systems are using the same type of Blowout prevention systems that use an annular valve which uses a rubber doughnut seal to close the supply pipe inlet. Lower on the blowout prevention assembly is a set of hydraulic valves that are designed to crush/cut the well pipe closed. There's no way this type of blowout prevention can be expected to perform a job that its not designed for. If as in here how are blind shear rams expected to work with a drill shaft in the hole? What's needed is a pressure control valve. If a blowout occurs with a pressure controller can be closed safely and means at a rate that will not create a "kick" or Pressure spike (hydraulic hammer). Using the old blowout prevention system on land based operations can guarantee blowouts will continue to happen. Example of using the kitchen sink faucet and trying to use your hand to stop the flow. You're gonna get wet, if using the faucet will work ok. I'm an oilfield mechanic and am currently 2019 employed on Alaska's North slope oilfields in Prudhoe Bay at the Kuparuk river unit for a company subcontracted to conoco Phillips. I have over 30 years of experience in pipeline repair and maintenance. I'm also the designer of the caphead used to stop the deep horizon's macondo well spill. I submitted my design to the "horizon helpline" but was stolen by BP as my design wasn't patented. I still have copies of my design submitted as well as emails to verify. This type of design blowout prevention system for land needs to go and replaced with a design that won't do the job of controlling pressure causing the drills to be spit out. I'm currently working on the upgrades needed on both land and ocean based oil and gas production drill platforms. That will prevent future blowout incidents. My designs are available but not free and will be patented. "007".
I'm not sure I am following your description. You mentioned blind rams and shear rams but no pipe rams. I have been on wells requiring 'stripping in' where 2sets of pipe rams we're needed to get past the tool joint. Are you referring to a check in the drill stem?
The question is : Does the presence of gas within the mud is a normal occurring event . If not then; what causes the gas to push the mud backward to the rig floor? What emergency plans did the crew trained about? What are safety warning devices that alerts the crew as the gas leaks on platform?
It's actually formation pressure exceeding hydrostatic pressure. HP>FP is the basis for all well control training. The easy way to think of those gas bubbles is that they might be the size of a grain of rice 3300' below the earth, but by the time it comes to surface could be the size of a small house. It's a shame 5 men lost their lives, lord have mercy.
Amazing video as always! But I have to ask, where does this background music come from? It seems more "techno" than the usual background music, like some kind of Boeing new plane reveal presentation music but it's lined with sad piano dings since this is obviously a tragedy... Either way I have to admit I really like it. Does USCSB make their own music or is it some kind of stock thing?
First off, why was the blow out preventer not activated as soon as they saw mud, second, why did it not activate after losing communications with the rest of the well?
why not have a section of the B.O.P. that's powered by springs and triggered by pressurized inert gas ampules......a fire superheats the ampule, causing it to explode, releasing a pair levers, that in turn releases the spring-loaded rams. the ampule is the only part that is exposed to the outside, and is protected by a thick piece of perforated steel plate. also, a second ramset, also spring loaded, with a flow sensitive mechanical trigger mechanism, a flow with too much volume trips a catch inside, releasing the rams, sealing the B.O.P.
Patterson, lol, operator error as usual. My first day on the job on my first rig site over 8 years ago was a Patterson rig. Within 12 hours they managed to drop the whole Kelly drive from the top of the rig in an uncontrolled fall. $250,000 of damage but fortunately the crew managed to outrun the falling pipe. Just dumb luck no one was KIA.
My little brother was a driller on a rig. Due to a complicated down hole assembly, the figures were wrong on how long the down hole assembly was. As a result, he crowned the kelly, snapping the cables. The kelly crashed 90 feet to the rig floor, wrecking it along with a lot of other stuff. No one was hurt, and my brother reported to the tool pusher, assuming he would be fired. The tool pusher said "Nope, I've never seen anyone crown the kelly twice. Since we just invested a couple of hundred thousand dollars in your education, you better be at work tomorrow." My brother is now President of one of the biggest tubing manufacturers in the industry, making a very heavy six figure salary. And no, he never crowned the kelly again.
Rip to the hands out there who lost their lives. I wonder why the anular or rams weren’t set after the tremendous amount of mud backing up into the pits.
You are correct, you get fair warning by the pits gaining volume. The mud becomes gas saturated losing its density and then displaced by gas. Been there and our idiot driller kept thinking we could get closer to bottom but us floor hands got tired of mud dripping off the girders on us.
@@lolbots yup. They get production and safety bonuses. I saw a hand roll and ankle and the drill manager just gave him t3s and heavily discouraged him from reporting it
Ive been watching so many of these vids, last night i had a dream that me and another worker were welding a scaffold structure and Carl Weathers (because dreams are random lol) came up and was like "so you guys got some hot work done?" And I was like "yes, hes been doing the work and showing me how to do it because I'm inexperienced, but I'm learning." So not only did I work on welding which id never done myself before, but even in the dream we were still being cautious not to go on the scaffolding until the tact welds were fully welded over
I'm pretty sure You are right, I see it's a fresh accident, i hope they will release more footage after investigation to show more deeply what safety system failed because that's the most interesting part for me, At that moment we know what happen but not why escalated to deadly scenario like on "Deepwater Horizon" case.
@@redmudpei possibly no one was in the cellar, but if there was enough flow to spill over the stack the driller should have noticed, there is also a flow counter on the flow line.
They were testing pipe/bottom hole assembly at the time of the well kick. they had just pulled the drill string out, and hadn't gotten to the part of closing the rams when all hell broke loose. Usually the weight of the mud int he hole keeps everything int he hole, by the time they saw the BOP overflowing it was too late.
I don't know why but I love these videos and wish there were more I think I'm almost out of them to watch! I fucking love you USCSB you have stolen mah heart
Excellent animations as usual. I have been using these at meetings on my work-sites for eleven years now. I put my package in on USAJobs, why don't you hurry up and hire me so I can be a part of these?
How can that actually ignite? Shouldn't that all be an ex area which requires all equipment to be gas tight, so no gas can leak into electrical devices and find a spark to ignite?
I really don't know much what goes on in the oil industry and my question is were they trying to put out the fire or did they ran from the explosion and died from falling debris?
They died in the shack. You don't get out of those situations running fire kills you even it doesn't touch you when it's that large and they weren't on the ground level.
This is not my industry, but it would seem to me that mud flowing out of the well would be a gravely bad indicator recognizable by someone with experience and or training. Either the person who noticed this was not trained well enough, or they were afraid to speak up with regard to safety. Both of those are the fault of management.
Kurt Richter I work on a drilling rig. We do weekly drills in this kind of stuff. 107 barrels of mud displaced is a huge amount to go unoticed. There would be alarms going off on the rig floor. They would know immediately, the video doesnt tell all information.
Kurt Richter No problem. Another thing to add is that during an active "kick" when it shows signs of the oncoming kick, there is typically a very short time to react. The time between "extra mud" and drilling mud shooting out of the rig floor could be less than a minute, depending on depth, gas formations etc. Its a very dangerous game we play.
Brandon Cody With the drill out of the well and all that mud coming up, shutting the BOP sounds like a good idea. Oh ...and run. It sounds like being in the path of an oncomming freight train.
They are highly trained and highly paid because of the years of experience it takes to learn how to do the work. It's similar to flying an airliner. You can't jump out and abandon the site because events are overtaking your crew. You have to man the controls and fight it out until you get it back under control or until events over take what can be done. Nuclear power systems are another case in point. You just have to work through the checklist and pray that it is completed before the thing blows.
They use a Bottom Hole Assemble (BHA) that has a rock bit, mud motor w/ a 1 to 2 degree bend about 4ft back of the bit, and about 120ft of non-magnet drill collar. The non-magnet drill collars house an electronics package that at a minimum would have an accelerator, magnetometer, and transmitter. The electronics package is indexed to the bend in the motor so the driller can point the motor bend in the required direction to drill the build (curve) or maintain inclination and azimuth.
I feel like a lot of these preventable accidents occur when you get bad conditions and workers who think science has no effect on them or their ability to make money.
Slow? Lmao I have never been on a slow crew. Ride blocks winch. Tackle stands when tripping in get ur ass in gear or get gone. They could have n should have closed pipe rams..... And stabbed the tubing.
Question: why the hell was anyone working what is, I believe, to be a physically demanding job at 1:12 am??? Anyone out there who can explain this to me? Seems quite silly to have workers do these fine technical maneuvers when they're likely to be very tired. This maneuver took 5 hours, finalizing at 6:10 am. Tired workers will make lots of mistakes. Is that what happened here? And why couldn't this be done at, like, 12 pm?
They have multiple crews that work 12 hour shifts. They are manned 24/7 because all that equipment is rented and oil in the ground doesn't earn interest. Drilling a well is like flying an airliner. It is too complex for one person to operate and it takes multiple people keeping an eye on multiple systems. The mud engineer has to monitor the specific gravity of the mud and adjust the formula to keep it at the correct weight. If they go through a pocket of water they have to stop and squeeze cement into the layer then drill through it to continue working the well. Every so many feet they have to stop and insert a steel liner to prevent the sides from collapsing into the well. The liner (casing) has to be cemented into place before they can continue drilling. Someone has to keep an eye on pressures and temperatures which are indicators to what is going on in the hole. When they get to the target depth the drill pipe is pulled up and downhole measuring equipment is rigged up to be sent downhole. Measurements are made and samples taken and a geologist decides whether their is an oil sand that can be tapped. To bring oil up they install a plug below the oil sand and another above it. They drill through the top plug and send down a tool to shoot holes through the casing into the sand to allow the oil to flow into the well. At that point the rig and it's equipment is hauled off. The mud pit is filled in. Oil tanks are installed and flow operations begin. After production starts no one is on site except periodically. I know I oversimplified the process but I hope it helps.
Natural gas escaped unchecked through the hole, ignited and literally cremated the crew. Since they had a blowout preventer on the well I assume they were able to eventually stop the flow of gas.
I heard about this I worked for them in my late 20s I hate hearing these stories and tripping out the hole wet is miserable that mud goes everywhere u gotta put a mud bucket on and im sure they were using the big on you gotta put on a wench its like 400lbs in middle of winter but if they all were on the floor they should've jumped or ran down stairs as soon as that mud based oil came up the pipe and blasted though the mud bucket floorhands its time to run or jump not go in doghouse I can just picture it they thought they could stop it but I was a floorhand and I ran off the floor many times your instinct kicks in cant stop mother nature and all it needs is a tiniest of spark ...RIP to the men just trying to take care of there families...makes my stomach queasy to burn up that way like in a oven being cooked they didn't die fast rest easy guys I feel you😢
I've read the "Factual Update" and watched this video a couple times; this is awful. It's like the script for this video was written by a petroleum engineering intern, they've heard the words but have no understanding of the processes. At 00:55 the video says they pumped a weighted pill intended to prevent gas from flowing into the well. That doesn't make sense. It's going to take a hell of a lot more than a pill to increase the hydrostatic pressure enough it's going to stop the well from flowing. It would seem more likely the the pill pumped at 00:55 was pumped for the same reason the pill at 01:25 they wanted to create a u-tube effect so that the pipe pulled out of the hole was empty of mud. At 01:33 the pipe was not plugged! If the pipe was plugged how was it possible for them to pump the pills at 00:55 and 01:25. If the rig was following proper hole fill procedure it wouldn't have matter if the pipe was pulling wet or dry. What I would like to see are the driller's trip log and mud pit volumes from the electronic drilling recorder.
It would be nice if there were no disasters to report upon, but dang do I love USCSB’s investigations.

Either way I have to admit I really like it. Does USCSB make their own music or is it some kind of stock thing?
doesnt sound stock, could be contracted or custom-made though
First off, why was the blow out preventer not activated as soon as they saw mud, second, why did it not activate after losing communications with the rest of the well?
why not have a section of the B.O.P. that's powered by springs and triggered by pressurized inert gas ampules......a fire superheats the ampule, causing it to explode, releasing a pair levers, that in turn releases the spring-loaded rams. the ampule is the only part that is exposed to the outside, and is protected by a thick piece of perforated steel plate.
also, a second ramset, also spring loaded, with a flow sensitive mechanical trigger mechanism, a flow with too much volume trips a catch inside, releasing the rams, sealing the B.O.P.
Patterson, lol, operator error as usual.
My first day on the job on my first rig site over 8 years ago was a Patterson rig.
Within 12 hours they managed to drop the whole Kelly drive from the top of the rig in an uncontrolled fall.
$250,000 of damage but fortunately the crew managed to outrun the falling pipe. Just dumb luck no one was KIA.
fun times
My little brother was a driller on a rig. Due to a complicated down hole assembly, the figures were wrong on how long the down hole assembly was. As a result, he crowned the kelly, snapping the cables. The kelly crashed 90 feet to the rig floor, wrecking it along with a lot of other stuff. No one was hurt, and my brother reported to the tool pusher, assuming he would be fired. The tool pusher said "Nope, I've never seen anyone crown the kelly twice. Since we just invested a couple of hundred thousand dollars in your education, you better be at work tomorrow."
My brother is now President of one of the biggest tubing manufacturers in the industry, making a very heavy six figure salary. And no, he never crowned the kelly again.
Rip to the hands out there who lost their lives. I wonder why the anular or rams weren’t set after the tremendous amount of mud backing up into the pits.
You are correct, you get fair warning by the pits gaining volume. The mud becomes gas saturated losing its density and then displaced by gas. Been there and our idiot driller kept thinking we could get closer to bottom but us floor hands got tired of mud dripping off the girders on us.
@@gregw8232 are drillers incentivized to take stupid risks or what
@@lolbots yup. They get production and safety bonuses. I saw a hand roll and ankle and the drill manager just gave him t3s and heavily discouraged him from reporting it
New animation technique. Nice!
Glad to see quality work still coming out of USCSB - these are dark days for doing intelligent things.
Does anyone know what the name of the song is that is used in the video?
I have no idea why I'm subscribed but wtf I love this channel
Ive been watching so many of these vids, last night i had a dream that me and another worker were welding a scaffold structure and Carl Weathers (because dreams are random lol) came up and was like "so you guys got some hot work done?" And I was like "yes, hes been doing the work and showing me how to do it because I'm inexperienced, but I'm learning." So not only did I work on welding which id never done myself before, but even in the dream we were still being cautious not to go on the scaffolding until the tact welds were fully welded over
Good analysis, good investigation
If you thought drilling for gas was easy hopefully this is enough to explain why it isn't even in 2018.
I'm not into oil industry but are not this should be prevented by BOP?
//Another good looking animation
I'm pretty sure You are right, I see it's a fresh accident, i hope they will release more footage after investigation to show more deeply what safety system failed because that's the most interesting part for me, At that moment we know what happen but not why escalated to deadly scenario like on "Deepwater Horizon" case.
The blind Ram closes like an elevator in something is jamming it up then it won't close. Happening so fast dont have time to react
@@redmudpei possibly no one was in the cellar, but if there was enough flow to spill over the stack the driller should have noticed, there is also a flow counter on the flow line.
A kick can happen so fast usually there is a mess before the blinds are closed. And if the rig caught fire quickly before someone could close them...
They were testing pipe/bottom hole assembly at the time of the well kick. they had just pulled the drill string out, and hadn't gotten to the part of closing the rams when all hell broke loose.
Usually the weight of the mud int he hole keeps everything int he hole, by the time they saw the BOP overflowing it was too late.
What is the value of a blowout preventer that does not prevent a blowout?
I don't know why but I love these videos and wish there were more I think I'm almost out of them to watch! I fucking love you USCSB you have stolen mah heart
at the first sign of more than a kick of mud coming up through the open BOP, why were the annulars not shut ...
It's odd because I live in Pryor OK, But didn't know there was a Pryor well in Pittsburgh county. (Not the county that Pryor is in.)
There are so many earthquakes in Oklahoma now, that coincided with so much drilling.
Great video
You guys need to do the gas explosion that happened in Massachusetts
Will there be an update video to this??
So from what I understand, they did everything correctly but just got unlucky with an angry well?
Nope, they did everything wrong and did not follow proper tripping procedures. Plus, no one saw the pit gain while they were on the bank?
When did they stop interviews and making safety recommendations?
Excellent animations as usual. I have been using these at meetings on my work-sites for eleven years now.
I put my package in on USAJobs, why don't you hurry up and hire me so I can be a part of these?
So who was at fault how could it have been prevented?
How can that actually ignite? Shouldn't that all be an ex area which requires all equipment to be gas tight, so no gas can leak into electrical devices and find a spark to ignite?
what's he saying at 0:34 ?? Crippin ??? and am i going deaf or does it sound like 'grilling' when he says 'drilling' ?
Tripping
this is well done learn something new everyday
Would be nice if they didn't have to contaminate shit when they drill
I really don't know much what goes on in the oil industry and my question is were they trying to put out the fire or did they ran from the explosion and died from falling debris?
They died in the shack. You don't get out of those situations running fire kills you even it doesn't touch you when it's that large and they weren't on the ground level.
these are fascinating.
He’s back! 😊
Where's the full vid!! It's over a year!
that was a pretty sweet beat, i wanna find it
What a crazy work day.
But what could they have done to prevent this? Was it human or technical error?
This is not my industry, but it would seem to me that mud flowing out of the well would be a gravely bad indicator recognizable by someone with experience and or training. Either the person who noticed this was not trained well enough, or they were afraid to speak up with regard to safety. Both of those are the fault of management.
Kurt Richter I work on a drilling rig. We do weekly drills in this kind of stuff. 107 barrels of mud displaced is a huge amount to go unoticed. There would be alarms going off on the rig floor. They would know immediately, the video doesnt tell all information.
Brandon Cody Thanks for the insight. Be safe!
Kurt Richter No problem. Another thing to add is that during an active "kick" when it shows signs of the oncoming kick, there is typically a very short time to react. The time between "extra mud" and drilling mud shooting out of the rig floor could be less than a minute, depending on depth, gas formations etc. Its a very dangerous game we play.
Brandon Cody
With the drill out of the well and all that mud coming up, shutting the BOP sounds like a good idea. Oh ...and run. It sounds like being in the path of an oncomming freight train.
Andrew White you can actually make things worse by shutting the BOP without being able to control it
This video is made with what software
Microsoft Paint.
Everyone on the well should be highly trained on conditions that pre-stage disaster and have a reaction plan to execute immediately.
They are highly trained and highly paid because of the years of experience it takes to learn how to do the work. It's similar to flying an airliner. You can't jump out and abandon the site because events are overtaking your crew. You have to man the controls and fight it out until you get it back under control or until events over take what can be done. Nuclear power systems are another case in point. You just have to work through the checklist and pray that it is completed before the thing blows.
HOW the F do they curve it?
They use a Bottom Hole Assemble (BHA) that has a rock bit, mud motor w/ a 1 to 2 degree bend about 4ft back of the bit, and about 120ft of non-magnet drill collar. The non-magnet drill collars house an electronics package that at a minimum would have an accelerator, magnetometer, and transmitter. The electronics package is indexed to the bend in the motor so the driller can point the motor bend in the required direction to drill the build (curve) or maintain inclination and azimuth.
@@eddydogleg complicated but ingenious inventions thanks for describing itd
Love the videos!
Keep up the good work!
I feel like a lot of these preventable accidents occur when you get bad conditions and workers who think science has no effect on them or their ability to make money.
A very unfortunate incident, butan excellent presentation nonetheless.
Things seem to go slow and methodical in the oil industry.
Then if something goes wrong...
It goes wrong real fast!!
Like flying.
Hours and hours of boredom followed by moments of sheer terror.
Slow? Lmao I have never been on a slow crew. Ride blocks winch. Tackle stands when tripping in get ur ass in gear or get gone. They could have n should have closed pipe rams..... And stabbed the tubing.
Question: why the hell was anyone working what is, I believe, to be a physically demanding job at 1:12 am??? Anyone out there who can explain this to me? Seems quite silly to have workers do these fine technical maneuvers when they're likely to be very tired. This maneuver took 5 hours, finalizing at 6:10 am. Tired workers will make lots of mistakes. Is that what happened here? And why couldn't this be done at, like, 12 pm?
They have multiple crews that work 12 hour shifts. They are manned 24/7 because all that equipment is rented and oil in the ground doesn't earn interest. Drilling a well is like flying an airliner. It is too complex for one person to operate and it takes multiple people keeping an eye on multiple systems. The mud engineer has to monitor the specific gravity of the mud and adjust the formula to keep it at the correct weight. If they go through a pocket of water they have to stop and squeeze cement into the layer then drill through it to continue working the well. Every so many feet they have to stop and insert a steel liner to prevent the sides from collapsing into the well. The liner (casing) has to be cemented into place before they can continue drilling. Someone has to keep an eye on pressures and temperatures which are indicators to what is going on in the hole. When they get to the target depth the drill pipe is pulled up and downhole measuring equipment is rigged up to be sent downhole. Measurements are made and samples taken and a geologist decides whether their is an oil sand that can be tapped. To bring oil up they install a plug below the oil sand and another above it. They drill through the top plug and send down a tool to shoot holes through the casing into the sand to allow the oil to flow into the well. At that point the rig and it's equipment is hauled off. The mud pit is filled in. Oil tanks are installed and flow operations begin. After production starts no one is on site except periodically. I know I oversimplified the process but I hope it helps.
so what happened?
Natural gas escaped unchecked through the hole, ignited and literally cremated the crew. Since they had a blowout preventer on the well I assume they were able to eventually stop the flow of gas.
SO BASICALLY, THIS IS BP DEEP WATER HORIZON, ON LAND??
this narrator might be the next david attenbrough
I heard about this I worked for them in my late 20s I hate hearing these stories and tripping out the hole wet is miserable that mud goes everywhere u gotta put a mud bucket on and im sure they were using the big on you gotta put on a wench its like 400lbs in middle of winter but if they all were on the floor they should've jumped or ran down stairs as soon as that mud based oil came up the pipe and blasted though the mud bucket floorhands its time to run or jump not go in doghouse I can just picture it they thought they could stop it but I was a floorhand and I ran off the floor many times your instinct kicks in cant stop mother nature and all it needs is a tiniest of spark ...RIP to the men just trying to take care of there families...makes my stomach queasy to burn up that way like in a oven being cooked they didn't die fast rest easy guys I feel you😢
That last image reminded me of Borderlands
Salute fellow hunter 🤙🏻
@@stxdude830 I salute you 🤙
Not going to lie, I thought the channel acronym said, “USCCB” (United States Conference of Catholic Bishops) and then realized it wasn’t haha
This happened on my last birthday, R.I.P.
I’m pissed because I broke a wood drill bit while drilling in some wood. Got to remove it with pliers
Love the videos but seems like the animations and detail in the newer ones has gone down. Your past videos have way more detail in them.
keep em' coming
Gaining 110 bbl in the pits without notice borders on criminal negligence
These are literally just "How Its Made: Disastors"
This sounds similar to the Deep Horizon disaster.
Everything is ok and good. Moved on and am not mad st him though I will used memories as song says.
I've read the "Factual Update" and watched this video a couple times; this is awful. It's like the script for this video was written by a petroleum engineering intern, they've heard the words but have no understanding of the processes. At 00:55 the video says they pumped a weighted pill intended to prevent gas from flowing into the well. That doesn't make sense. It's going to take a hell of a lot more than a pill to increase the hydrostatic pressure enough it's going to stop the well from flowing. It would seem more likely the the pill pumped at 00:55 was pumped for the same reason the pill at 01:25 they wanted to create a u-tube effect so that the pipe pulled out of the hole was empty of mud. At 01:33 the pipe was not plugged! If the pipe was plugged how was it possible for them to pump the pills at 00:55 and 01:25. If the rig was following proper hole fill procedure it wouldn't have matter if the pipe was pulling wet or dry. What I would like to see are the driller's trip log and mud pit volumes from the electronic drilling recorder.
this incident broke my prior trust
always blowing out MUD
