- bp launched an internal investigation into what happened during the accident at Deepwater Horizon in the Gulf of Mexico on 20 April 2010. These results are presented in this video. For more from bp, subscribe to our TH-cam channel: / @bpplc
The accident at the Deepwater Horizon led to an explosion and fire that killed 11 people and caused pollution in the Gulf of Mexico. This video goes through the happenings step-by-step, while showcasing the key findings from the investigation. The investigation into the accident showed that no single factor caused the tragedy in the Macondo well, but rather a sequence of failures leading up to the accident. The full report can be read at bit.ly/BP_Report.

There is no mention of the decision to not run a cement bond log following the cement job. The logging company crew and tools were on board, however BP chose to not carry out the CBL. I believe the reason invoked by BP was it was not deemed necessary during the drilling phase, and would have been done after. Given the technical difficulty of running a nitrified cement job, it would have made sense to verify the integrity by running the CBL/VDL log. Such a log would have identified the cement job was not successful. Why did you leave out such an important part in your narrative?
The number of centralizers to be used is vital in aiding a good cement job. Major flaw going with only six. Why leave out that Halliburton warned about severe gas flow problems following a bad cement job because of non-centralized pipe? Why not highlight the incomplete bottoms up? Halliburton warned about this as well - risk of trapping hydro carbons in the top of the well. How about your conclusion on no losses during the cement job ? How exactly do you go forward measuring volume changes in a foam cement in the field ? (when it is 100bbl on the mixing unit and then the same batch is only 50bbl when pumped...) I can tell you that would require advanced computer simulation tables. Why did you skip the cement bond log, and not perform TOC? (tag top of cement ) Why did you rush testing the cement job and not wait the 48h before ? Halliburton said it would require that amount of time for the cement to cure. Why not question the fact that the Transocean toolpusher asserted the evidence from the negative pressure test was due to a well leak but BP company man said no - it is an anomaly from the riser leak?? And who does not see the gravity of a pressure change in the drillpipe from 273psi to 1250psi in six minutes?! That later increased to 1700psi and then fell to 700 - before it shot back up to 1300psi.. something strange going on maybe ? How do you justify operating with only one well barrier intact during the temporary abandonment procedure when the hanger seal was set AFTER displacing the mud with seawater? Let's say something about the automatic shutdown system ESD, that was set in manual mode by rig crew before the incident. I would not call that an equipment failure.. more bad mistake. Fair enough you didn't mention the miswiring in the SEM modules on the bop control pods, this was uncovered by nasa at a later time, 27V battery low voltage is correctly another fault though. You failed to mention that the mudloggers advised against offloading mud to the supply vessel whilst you were doing the final displacement of mud to seawater - and you went ahead anyways. This means no volume control, hence why the influx freely flowed up to the rig. And why not mention that you in the first place wanted to save some money so you went with the long string 7in -> 9 5/8in instead of a normal tieback solution? The latter would provide better barrier function against influx of hydro carbons. You so nicely claim in the beginning of the video that you are not playing the blame game, but you are deffinately not playing the honest game either. People who watch this: keep in mind that hearing the one side of the story does not reveal the complete truth. I wrote this because I was so astounded by the lack of and misinformation delivered in this video. My thoughts go out to the rig workers who both made it home from this tragedy and also those who did not, their families included. May their souls rest in peace and this sort of accident never happen again.
Who came here after watching the movie?
Typically when you look at an accident chain, you find a series of seemingly inconsequential event that that lead to disaster (e.g. Value Jet 592). In this case, every last failure would or should have been considered significant, from the half-assed cement design job all the way through to the failure to recognize that the gas-liquid separator was overwhelmed. This suggests problems with corporate culture above and beyond the factors discussed here.
One thing, its was made known that the cement being used was unsafe and would not hold. But they used it anyway.
awesome observation! check my post
Their real mandate was to make sure that they dont get blamed, they will not have to pay a dime, and do nothing to stop the spilling oil.
Knew of pressure problem for about an hour, yet BOB was not engaged!
Thanks for the honesty, but what were people thinking!
You forgot about the well design change and the omission of 15 of the original 21 centralizers. Wasn't there some issue with the inspection of the cement job? While I can understand that BP is treading lightly for legal reasons, maybe this sort of thing would have been better suited for a neutral party after the official investigation has been completed
The first and foremost mistake was made when authorities allowed BP to begin drilling 13000-foot-deep well, 5000 feet below the surface in the middle of Louisiana's seafood production waters. Crucial question is what are you going to do if your blow-out preventer doesn't work when your 5000-foot-long, 20-inch casing breaks in the middle of the ocean? BP people would have explained:" Those sets of circumstances are unlikely to occur simultaneously". The lesson learned from this story is:" Hope for the best, but plan for the worst!!!".
BP was the Boss! The well, the crew and rig is under their command!
I think BP may be the most hated channel on TH-cam...
WAIT, never mind! that was close! I FORGOT Fred!
@youbeat2008 How do you clean up dispersed oil? Some of it is in sediments on the ocean floor, but much if it is still kinda lurking out there somewhere beneath the surface of the waves and possibly even in the sea food that the "scratch and sniff test" is supposed to tell us that it is safe.
CRIMINALS
I wonder if there is a version in Layman's terms of what happened.
So the accident happened on 4/20 ? That explains it right there.
Thanks for sharing. What you could not mention: Similar to the space shuttle, where the changeover from CFC foaming to nitrogen foaming of the tank for environmental reasons led to the root cause of the crash, the root cause of this incident becoming a catastrophe was the routing of the diverter discharge to the mud-gas separator instead of directly overboard, again for environmental reasons to avoid accidental hydrocarbon discharge... Had it gone directly overboard - no fire.
Typical oil company men cutting corners to save money
SAD!
Cant wait to see National Geographics Version... SECONDS FROM DISASTER.
Are the well test procedures and results now approved at higher levels within BP & contractors? is there any 3rd party or government involvement in the acceptance of the well test procedures and the well test results? Due to the amazingly slow response time of the crew are there plans to mandate automated actions to well and BOP control systems?
question. when he says over-speed. does he mean the engines go faster? because test have been done with methane. and you would might be surprised at the results,..
While much of this was interesting. And now is May of 2013. When this video was made I'm sure the reason's you left out the Pre-tower safety meeting chest bumping that took place between BP'S company man and Halliburton's on site Team Manager over pre-mature offloading of the mud is do to the lawyers.Putting all that aside. The fact that BP adopted and implemented all the time wasting proven to not be effective IKSTOK Spill Tophat,Junkshot nonsense from 1979 caused a local to shoot himself.
I can't believe all you commenters missed the key/root cause of all the subsequent events Haliburton tested the cement in their lab for weeks and COULD NOT!!! get a successful test so after several mixtures they found a marginal test pass and sent to the rig.. hmmm hmmmmm should the crew have caught it -- maybe? --- but the world will never know.
+All Sewe This could be explained by complacency. According to my personal experience, for such sensitive cement jobs, a witness of the operator would always participate in the testing phase. For such a technically challenging nitrified cement job, I fail to understand how this could have gone ahead like it did.
Good explanation, a bit wishy washy though. Conservative explanations but people can read the full report if they wanted to.
The presentation is so calm and factual. It is strange to think that one is witnessing a chain of events that violently killed eleven people.
good presentation
Why cant British Petroleum admit they were at fault and accept responsibility and STOP trying ti displace blame???
I'd of pissed on the sparkplug if it would have helped!
Thanks for posting this information. I am sure that BP like all of us does not want this to ever happen again. I hope a fair accounting of the responsible actions for recovery continue...
@923TARA The MC 252 well has been shut in since July 15 and therefore activity among the remotely operated vehicles (ROVs) near the seabed is now limited. Additionally, footage may be off-line due to ROVs being out of service due to maintenance and/or operational task-specific breaks.
@CorporateRule SHOULDNT HAVE HAPPENED IN THE FIRST PLACE.......
@TheHaterzMad I like your comment... BP SHOULD have had a plan to plug a hole in case fail-safty failed. This is a tragic disaster that should certainly change the world as well as the saftey of oil drilling mechanisms forever. This video is to help engineers and companies do things smarter in the future, so it's good that BP put it on youtube, and I like that they're allowing for comments instead of trying to suppress the hatred.... takes balls cuz they WILL NEVER hear the end of it, lol.
???
good explanation.understood all this like a boss because I work on the rigs.im a mud logger.
@ExpertOfSound theres actualy people who like him through.
@H1ghW1sdom1
He MIGHT come in third.
:D
Does he have his own channel? lol
@whateverrah
Yea i'd say you are right about that :D
Thanks for recognizing this. We understand people have varied opinions about BP and welcome both our supporters and critics in order to have an open conversation and debate.
@PhillipIsAzn02
LOL, that is true haha
TL;DR
gg
Regardless of what caused the biggest oil spill in history, the big question remains to ask yourselves: How can this kind of disaster be prevented from happening again? My answer: MAKE FRIGGEN WIND MILLS!
BP was the Boss!
Are we going to die?
for those who are standing against BP
do u think any company will intentionally do mistakes which are extremely harmful against themselves, without any big advantages? if BP got an advantage from deep water hazard, what is that?..think wise fully.
In my opinion, all barriers which helps to avoid hazards has some disadvantages, let take it as a hole.....in this incident those holes in different barriers came aligned which lead to a big hazard. now implement methods to avoid getting them aligned..
This is objectively informative. Thanks
Well, wonder why we are so slow at producing and selling bio diesel. Maybe because the oil companies have too many offices in Washington for lobbying, that's why renewable energy are in the shit hole. If we switch quicker none of this would have happened. Oil should never be used for energy, production of products like plastics maybe, but not for transportation. That's why I invest in Archer Daniels Midland instead of big oil companies, but too bad big oil is still in total domination.
@ExpertOfSound SERIOUSLY WHO THE HELL CLICKED LIKE? i allways wanted to see like 1,000,000 dislikes and 0 likes
14 people work for Bp........ an why the hell do they keep making these videos? their propaganda is worse that stalins!!
Honest, comprehnsive and unbiased.

We can assure you that our commitment to safety is an important value at BP. We'll continue with measures like our safety audits and big rig audits, coupled with heightened expertise, to prevent accidents and spills. Visit our website to view our continued efforts.
When I first heard about this incident, I suspected the Good Ole Boys who run the oilfield in that part of the world. BP's video confirms it. Lets face it - the guys on the rig calling the shots were totally lost and had no idea how they should be reacting. They would never make it in the North Sea but - hey - what do foreigners know about drilling anyway?
You obviously know that this was no accident.In the weeks prior to the explosion the company that produces the dispersant was purchased by BP.Along with this the CEO offloaded 1/3 of his stockholding in the company.The people who worked on the Exxon Valdez oil spill are dead from the use of the dispersant.You sir are living in a dream if you think this was "unplanned".The corporatocracy must bare the responsibility for this man-made disaster. Rgds Arth
Boom it exploded thats what happend the 28:56 was a waste of time
Well, you made it right for us again, BP!
Coastal business is up and profits are soaring again because you kept your promise to all Americans. The beaches are clean and the water is warm, let the summer good times begin again!
We salute BP for its tireless commitment to the people of the affected areas, no other profit-seeking company could have achieved what BP did nor could anyone else have accomplished such a massive undertaking in so short a time!
For all that you do BP... THANKS A MILLION!
