-- why it's taken so long to find a permanent stop to weaken.
What went wrong in the first place none other than bill guy the science up -- god and Bill Nye the Science Guy.
-- -- guide to assign lab whatever thank you bill for coming in very public that you brought as we said did a moment ago some props with you learn this actually and I.
Wishing you spared no expense no expense.
So let's say this is the sea floor -- and here's your blowout prevent or which you -- were called them prevent anything right or the reason it's taking so long.
So let's just think back you know to drill the well in the first place to come from October to end of April -- cut.
Yeah so it's taken a few months to draw a whole -- well coming down from a whole new direction to try to believe it to plug it off to plug it weighed down here.
We remind everybody that thing goes weighed down below the -- force so here's what I am concerned about a bit.
People said well let's start pumping drilling fluid into the blowout prevent her and force the oil down the thing about this business.
It's really kind of intuitive.
And it's it's plumbing.
It really is however it's at almost 7000 PSI.
A mile to the sea floor and another two miles hit bottom so it looks out of -- everyday experience for straws kind of -- -- -- at -- so here's -- -- button.
So what you drill oil -- you have casings so bright yellow ones a bigger diameter than the Greenland which is a bigger diameter than the white one.
So if you when you put a cap on this thing.
Stop it then you cap it off.
Affluent well look yeah pressure builds up down here so it's almost certainly leaking.
Somewhere along this casing.
So my concern is simply -- mud down for and mud is an expression for drilling fluid right that's -- natural stuff static kill method they're talking out of this if you if we start doing that right and I'm not there on site and so on but if we start doing that there's a chance that this drilling mud -- lock up.
Part way down.
Then -- have a slug of oil and here are so that when you ultimately do drill the relief well in and you try to pump mud up.
You'll be fighting against stuff in the oil and here we'll have to find a way out so much so that if that's the case then why not just wait.
Bob with the cap in place for the relief well to be fit all of us as.
I think the reason is everybody so anxious live look so simple.
What they just put a cap on that thing but now I have a cap is there are risks to waiting also because it looks to me -- -- everybody it's seeping right -- if you think if this tropical storm comes in and search shaking stuff.
The cap could come loose and then blow off and then -- got another mass.
And and then it did seems to me it took him so long to get that thing nestled in the -- locked down.
That they ought to leave it there however.
I hate you we are not there we are not looking at the -- reason with the decisions -- -- -- what would you do this thing.
This this -- runs up to the surface well what were erected this scale.
Well above the roof of this building -- -- -- 38 stories on the on the -- -- -- had some nice yes so.
Do you let it float under water -- tropical storm comes -- running through their do you try to keep this ship on station.
Holding on to this thing or you're just gonna hack with a letter rumbles out of trouble come back later that they had none of these are good choices right in line up so was so which one would you pick -- -- -- what we're doing that however the oilfield -- -- knowing.
What I know now I would leave the cap in place and try to have a brutally on the -- a drawn from the site continue that effort when yet after the storm blows through.
But leave it floating with a neutrally buoyant or not especially poignant thing she could grab hold that -- again later and just take a chance because when you get down that deep.
Now tropical storms don't affect the currents for him.
But she'll fold on the design of this in the first place anything of that depth look that far down there's got to be risky.
Well it's risky it's very good question but the problem here reminds me very much of airplane safety.
And had these pressure tanks called -- Q your players when the British expression.
And there was no I didn't have enough pressure and they had batteries and the batteries were dead and so it's a classic thing where.
The inspectors weren't inspecting and the safety systems weren't maintain.
And than when you needed -- thing to prevent something you know they have these rams that -- -- To slam -- off in fact one of the rams is so powerful how powerful is it.
It's supposed to be able to cut through the drill string that the steel.
It's about as big as well but -- -- -- my forearm and it would cut right through the super hard steel.
But there wasn't enough energy and in the batteries are became the -- to drive that as a safety systems weren't.
Didn't prevent any.
But since we have gotten to this on April 20 and needed the explosion did take place and they had to be some response to -- killing eleven people.
Has BP's response -- the methods that they tried one after another didn't sound scientifically -- I have tried something else first did they got about right yeah I think they did very reasonable thing you know but the first thing was lowering this.
How was like thing on top of the -- gushing oil and then something happened that.
People are aware of but -- kind of forgotten about these class three its form.
Methane hydrate ice and to me when are you I want you are working also just for a couple years most of my time -- in harassment but.
And -- this was a laboratory curiosity.
You have this methane ice you could light it on fire and holed that in the palm of your hand -- -- -- the super high pressure oil came flying out of this thing.
It's spread out so fast it's molecules spread out so fast -- energy spreads out so fast they turn cold.
-- and froze.
Up inside this house the first house they tried.
And nobody everybody.
Core in half in and -- -- because there's so much gas so called in trained were carried with the oil so then.
They tried other things to kind of -- did -- and then they finally designed to cap.
Big enough and strong enough with the big rubber gasket.
-- hold on -- that things and then you may remember.
They close the vents on that and we just set this down.
They close the vents on that slowly and to keep from close if you close it hard.
You get a pressure wave in this huge drill string that could crack it again are you surprised that no contingency in place for something like this now.
Sorry rash and -- used to work in the -- field and when this stuff goes wrong on land.
It's not a big deal.
And you know I mean it was a big deal but -- you bring bulldozers then chair you build a berm around it you you've tried it close to prevent -- you try to put another prevent or on top and then close.
And it's just much more manageable number 800.
Thousands oil wells around the world right 3500 offshore rigs about.
Something else is gonna go wrong and people my colleagues and I mean I'm open minded but people want to have solve the energy crisis by building nuclear power plants.
This sounds really great idea you dig up uranium.
You fuel efficient it for awhile you buried again the idea it would make sense.
But when there are 20000.
Nuclear power points.
He'll have another accident except it'll be another -- seriously it's heavy industry.
That hasn't been regulated for a long time and they'll mine it went wrong thanks we got -- to project what -- -- thanks so much the science guy with us today now.
