Greetings folks, with the untamed methane/oil gusher in the Gulf of Mexico (and which threatens to be a planetary disaster - more on this later), we've not been paying much attention until recently of the other most urgent environmental issue facing us. Global Warming. As we've mentioned before in previous articles, we are in UNCHARTED WATERS, scientifically, and environmentally speaking, when it comes to the state of the atmosphere, and it's increasing CO2 and Methane concentrations, from our reliance on fossil fuels.
Research has shown that the last time the concentration of CO2 in the atmosphere was as high as it is now, 390 ppm (from naturally occuring volcanism then), 200,000 years ago, global sea levels were five to seven metres higher. What is not known about then, is how long it took for those sea levels to rise, based on how fast the atmospheric CO2 levels increased. So, in our estimation, here at A.P.R., based on our decades of experience analysing the global weather and climate, we have to expect, that this is going to happen again. But when? Well, as our previous articles have described, disturbing signs are appearing on the Greenland ice sheet, and in portions of the fringes of Antarctica. Melt water has opened holes through these each summer, over the past decade or more, and it's surmised that this water flowing down to the bottoms of these glacial sheets is acting to lubricate the bases of them, which could allow them to surge rapidly, possibly even in massive chunks, breaking from their land base, then slumping into the surrounding seas. Which would then create catastrophic sea level rises, in a period of 10 to 20 years, possibly faster! IT'S NOT A MATTER OF IF, BUT WHEN! Remember also, CO2 concentrations are increasing now at 3-4 ppm per year, so 30 years from now, it will be at least 500 ppm, possibly more. Which has never appeared in the past several million years (though in the End-Permian extinction event, 250 MYA, volcanism-released CO2 reached greater levels, and 95% of all life on Earth disappeared from the geological record!).
But will it be ten years from now, twenty, fifty, or a hundred? There are researchers trying to assess this, but the U.S. and other governments so far have not really put alot of emphasis or funding into this vital research question. Which will affect the state of civilisation as we know it.
This is the latest from the National Snow and Ice Data Center, Arctic Sea Ice News and Analysis:http://nsidc.org/arcticseaicenews/

Arctic sea ice extent declines rapidly in MayIn May, Arctic air temperatures remained above average, and sea ice extent declined at a rapid pace. At the end of the month, extent fell near the level recorded in 2006, the lowest in the satellite record for the end of May. Analysis from scientists at the University of Washington suggests that ice volume has continued to decline compared to recent years. However, it is too soon to say whether Arctic ice extent will reach another record low this summer—that will depend on the weather and wind conditions over the next few months.

Arctic sea ice extent averaged 13.10 million square kilometers (5.06 million square miles) for the month of May, 500,000 square kilometers (193,000 square miles) below the 1979 to 2000 average. The rate of ice extent decline for the month was -68,000 kilometers (-26,000 square miles) per day, almost 50% more than the average rate of -46,000 kilometers (18,000 square miles) per day. This rate of loss is the highest for the month of May during the satellite record.
Ice extent remained slightly above average in the Bering Sea, and below average in the Barents Sea north of Scandinavia, and in Baffin Bay.

Conditions in context
As we noted in our May post, several regions of the Arctic experienced a late-season spurt in ice growth. As a result, ice extent reached its seasonal maximum much later than average, and in turn the melt season began almost a month later than average. As ice began to decline in April, the rate was close to the average for that time of year.
In sharp contrast, ice extent declined rapidly during the month of May. Much of the ice loss occurred in the Bering Sea and the Sea of Okhotsk, indicating that the ice in these areas was thin and susceptible to melt. Many polynyas, areas of open water in the ice pack, opened up in the regions north of Alaska, in the Canadian Arctic Islands, and in the Kara and Barents and Laptev seas.

Many polynyas, areas of open water in the ice pack, opened up in the regions north of Alaska, in the Canadian Arctic Islands, and in the Kara and Barents and Laptev seas.
The polynyas are clearly visible in high-resolution passive microwave images from the Advanced Microwave Sounding Radiometer (AMSR-E) aboard NASA’s Aqua satellite. What do current ice conditions mean for the minimum ice extent this fall? It is still too soon to say: although ice extent at present is relatively low, the amount of ice that survives the summer melt season will be largely determined by the wind and weather conditions over the next few months.
What this article is showing, is this. The Arctic sea ice, once again, is approaching record low-levels this year, and stands a very good chance of breaking 2007's record low summer extent. And, it is 3.5 standard deviations below the 1979-2000 average. Summer so far here in Alaska has been only slightly above-average, temperature-wise, for the bulk of the interior, and along the southern coastal fringes. But along the North Slope and in the Arctic Ocean just to the north, high pressure ridging has been dominating for the past few months. Which basically is a warmer than average air-mass. As long as this pattern continues, and continues to recur more often (which it is), summer temperatures over the Alaska and Western Canadian portion of the Arctic will remain above average, and increased ice melting will continue. Already, much more of the Arctic ice, as a whole, is thinner now than in decades past, as much as 30-40%, as it freezes later in the fall, and melts earlier, each spring. Global climate change modeling was, just up to five years ago, predicting summer ice-free Arctic Ocean conditions not occurring until 2060 or 2070. Now, many climate researchers are estimating it will happen in five to ten years. This will be a "tipping point" in the global climate balance, as then the Earth's overall "albedo" (the percentage of solar radiation reflected back to space, which is a net cooling factor), will be greatly increased. The waters of the Arctic Ocean will warm up much more quickly, absorbing much more solar radiation, and will then take longer to freeze in autumn. This warmer water will help erode the bases of the glaciers of Greenland, and the northern Canadian Islands (such as Baffin and Ellesmere Islands).
This combined with their summer melt lubrication of their bases, could then result in their quick collapse into the surrounding seas, and then the rapid global sea level rises. This is why, in our previous article, a fictional future projection, we came up with those timelines. We hope we are too soon in this projection, but all the World governments, and the UN need to understand, THIS IS GOING TO HAPPEN, AND WE NEED TO START PLANNING FOR IT.
PANDORA'S WELL
All of us here at the Alaska Progressive Review like to look at things in a positive constructive light, when we can. And to realise that we all have a significant hand in creating our own personal realities, based on our own beliefs and expectations.
However, sometimes large-scale events are of such significance, that we have to have to realise, this is going to affect all of us, in ways that could be very detrimental, and we need to stay abreast of the latest ACCURATE information, and share it with you. The untamed British Petroleum methane/oil gusher, 1500 metres below the surface of the Gulf of Mexico, stemming from a blown-out well that extends another 6100 metres (20,000 feet) below the sea-floor, IS AN EVENT WITHOUT PRECEDENT IN HUMAN HISTORY, and has the potential to harm not just the Gulf of Mexico's ecosystems (frankly, it looks like much of the Gulf will soon be a dead zone), but eventually the Atlantic Ocean's, and possibly more.
Before we delve more into that, did any of you listen to President Obama's speech earlier this week? I'm sorry, but we gave him some benefit of our doubt when he was elected, but almost nothing his administration has done, has been much different than the previous criminally sociopathic Bush's. The appointing of Wall Street criminals to high posts in the current administration, no change in ending the disastrous, immoral, and bankrupting wars in Iraq and Afghanistan, and now, still catering to the oil industries whims.
But in his speech, he actually said that the "Gulf would be restored to not just as it was before, but better!" That is not going to happen, in any of our lifetimes. We're sorry to say. And he had to have known this, had to! Because there are thousands of competent scientists working in the federal government who can, and have, analysed the video stream of the gushing blown-out well on the sea-floor. And who have calculated that the actual gush rate is between 60,000 and 115,000 barrels per day (10,080,000 to 19,320,000 litres). Or, one Exxon Valdez spill, every 4 to 5 days, since 20 April! And even if British Petroleum is able to do as they say, and drill relief wells, which would then take the pressure of this one, that is still two months, minimum, away, not counting any hurricane disruption! So why the overt lies? Well, our best guess, is to cover for his corporate patrons, who got him elected, and keep the pressure on him. But the grim reality of what will happen to the Gulf of Mexico, it's ecosystems, fisheries, tourism, and hence, economic base, will not be denied, in the coming months. Which will spread throughout the USA. A large percentage of the seafood consumed in this country, comes from the Gulf of Mexico. Agriculture in Florida has the potential to be adversely affected, if oil-laden winds blow inland from tropical storms or hurricanes. And what of the health effects of this on the people in these areas?
This is actually worse, for this administration, and the country, than Chernobyl was, for the Soviets. Because at least with Chernobyl, once the fires in the graphite control-rod dampered nuclear reactor's core were extinguished, and then covered with cement sarcophagi, the uncontrolled emission of deadly radiation ceased. And although several hundred thousand people had to be relocated, it was a one-time event. Not a continuing one. People around the Gulf of Mexico are going to learn a hard lesson what unrestrained Capitalism brings.
However, that is the best-case scenario. I'm almost despondent having to share this information, because it is heart-breaking, and terrifying, if it is true.
We found this web-site last week, which is moderated by professionals in the global oil industry, and has knowledgeable contributors who provide informed commentary. This particular link has a discussion of the Deepwater Horizon tragedy, and what this particular commenter's take on it is. He is a professional in the oil industry. Here is some of that discussion, then we'll provide some of our own commentary, it's long, but worth the reading, because it describes the mess in terms everyone can understand:
"Editors' note for first-time visitors: What follows is a comment from a The Oil Drum reader. To read what The Oil Drum staff members are saying about the Deepwater Horizon Spill, please visit the front page. (Were the US government and BP more forthcoming with information and details, the situation would not be giving rise to so much speculation about what is actually going on in the Gulf. This should be run more like Mission Control at NASA than an exclusive country club function--it is a public matter--transparency, now!)
OK let's get real about the GOM oil flow. There doesn't really seem to be much info on TOD that furthers more complete understanding of what's really happening in the GOM.
As you have probably seen and maybe feel yourselves, there are several things that do not appear to make sense regarding the actions of attack against the well. Don't feel bad, there is much that doesn't make sense even to professionals unless you take into account some important variables that we are not being told about. There seems to me to be a reluctance to face what cannot be termed anything less than grim circumstances in my opinion. There certainly is a reluctance to inform us regular people and all we have really gotten is a few dots here and there...
First of all...set aside all your thoughts of plugging the well and stopping it from blowing out oil using any method from the top down. Plugs, big valves to just shut it off, pinching the pipe closed, installing a new bop [blow out preventer, eds] or lmrp, shooting any epoxy in it, top kills with mud etc etc etc....forget that, it won't be happening..it's done and over. In fact actually opening up the well at the subsea source and allowing it to gush more is not only exactly what has happened, it was probably necessary, or so they think anyway.
So you have to ask WHY? Why make it worse?...there really can only be one answer and that answer does not bode well for all of us. It's really an inescapable conclusion at this point, unless you want to believe that every Oil and Gas professional involved suddenly just forgot everything they know or woke up one morning and drank a few big cups of stupid and got assigned to directing the response to this catastrophe. Nothing makes sense unless you take this into account, but after you do...you will see the "sense" behind what has happened and what is happening. That conclusion is this:
The well bore structure is compromised "Down hole".
That is something which is a "Worst nightmare" conclusion to reach. While many have been saying this for some time as with any complex disaster of this proportion many have "said" a lot of things with no real sound reasons or evidence for jumping to such conclusions, well this time it appears that they may have jumped into the right place...
TOP KILL - FAILS:
This was probably our best and only chance to kill this well from the top down. This "kill mud" is a tried and true method of killing wells and usually has a very good chance of success. The depth of this well presented some logistical challenges, but it really should not of presented any functional obstructions. The pumping capacity was there and it would have worked, should have worked, but it didn't.
It didn't work, but it did create evidence of what is really happening. First of all the method used in this particular top kill made no sense, did not follow the standard operating procedure used to kill many other wells and in fact for the most part was completely contrary to the procedure which would have given it any real chance of working.
When a well is "Killed" using this method heavy drill fluid "Mud" is pumped at high volume and pressure into a leaking well. The leaks are "behind" the point of access where the mud is fired in, in this case the "choke and Kill lines" which are at the very bottom of the BOP (Blow Out Preventer) The heavy fluid gathers in the "behind" portion of the leaking well assembly, while some will leak out, it very quickly overtakes the flow of oil and only the heavier mud will leak out. Once that "solid" flow of mud is established at the leak "behind" the well, the mud pumps increase pressure and begin to overtake the pressure of the oil deposit. The mud is established in a solid column that is driven downward by the now stronger pumps. The heavy mud will create a solid column that is so heavy that the oil deposit can no longer push it up, shut off the pumps...the well is killed...it can no longer flow.
Usually this will happen fairly quickly, in fact for it to work at all...it must happen quickly. There is no "trickle some mud in" because that is not how a top kill works. The flowing oil will just flush out the trickle and a solid column will never be established. Yet what we were told was "It will take days to know whether it
worked"...."Top kill might take 48 hours to complete"...the only way it could take days is if BP intended to do some "test fires" to test integrity of the entire system. The actual "kill" can only take hours by nature because it must happen fairly rapidly. It also increases strain on the "behind" portion and in this instance we all know that what remained was fragile at best.
Early that afternoon we saw a massive flow burst out of the riser "plume" area. This was the first test fire of high pressure mud injection. Later on same day we saw a greatly increased flow out of the kink leaks, this was mostly mud at that time as the kill mud is tanish color due to the high amount of Barite which is added to it to weight it and Barite is a white powder.
We later learned the pumping was shut down at midnight, we weren't told about that until almost 16 hours later, but by then...I'm sure BP had learned the worst. The mud they were pumping in was not only leaking out the "behind" leaks...it was leaking out of someplace forward...and since they were not even near being able to pump mud into the deposit itself, because the well would be dead long before...and the oil was still coming up, there could only be one conclusion...the wells casings were ruptured and it was leaking "down hole"
They tried the "Junk shot"...the "bridging materials" which also failed and likely made things worse in regards to the ruptured well casings.
"Despite successfully pumping a total of over 30,000 barrels of heavy mud, in three attempts at rates of up to
80 barrels a minute, and deploying a wide range of different bridging materials, the operation did not overcome the flow from the well."
80 Barrels per minute is over 200,000 gallons per hour, over 115,000 barrels per day...did we seen an increase over and above what was already leaking out of 115k bpd?....we did not...it would have been a massive increase in order of multiples and this did not happen.
"The whole purpose is to get the kill mud down,” said Wells. “We'll have 50,000 barrels of mud on hand to kill this well. It's far more than necessary, but we always like to have backup."
Try finding THAT quote around...it's been scrubbed...here's a cached copy of a quote...
"The "top kill" effort, launched Wednesday afternoon by industry and government engineers, had pumped enough drilling fluid to block oil and gas spewing from the well, Allen said. The pressure from the well was very low, he said, but persisting."
"Allen said one ship that was pumping fluid into the well had run out of the fluid, or "mud," and that a second ship was on the way. He said he was encouraged by the progress."
Later we found out that Allen had no idea what was really going on and had been "Unavailable all day"
So what we had was BP running out of 50,000 barrels of mud in a very short period of time. An amount far and above what they deemed necessary to kill the well. Shutting down pumping 16 hours before telling anyone, including the president. We were never really given a clear reason why "Top Kill" failed, just that it couldn't overcome the well.
There is only one article anywhere that says anything else about it at this time of writing...and it's a relatively obscure article from the wall street journal "online" citing an unnamed source.
"WASHINGTON—BP PLC has concluded that its "top-kill" attempt last week to seal its broken well in the Gulf of Mexico may have failed due to a malfunctioning disk inside the well about 1,000 feet below the ocean floor.
The disk, part of the subsea safety infrastructure, may have ruptured during the surge of oil and gas up the well on April 20 that led to the explosion aboard the Deepwater Horizon rig, BP officials said. The rig sank two days later, triggering a leak that has since become the worst in U.S. history.
The broken disk may have prevented the heavy drilling mud injected into the well last week from getting far enough down the well to overcome the pressure from the escaping oil and gas, people familiar with BP's findings said. They said much of the drilling mud may also have escaped from the well into the rock formation outside the wellbore.
As a result, BP wasn't able to get sufficient pressure to keep the oil and gas at bay. If they had been able to build up sufficient pressure, the company had hoped to pump in cement and seal off the well. The effort was deemed a failure on Saturday.
BP started the top-kill effort Wednesday afternoon, shooting heavy drilling fluids into the broken valve known as a blowout preventer. The mud was driven by a 30,000 horsepower pump installed on a ship at the surface. But it was clear from the start that a lot of the "kill mud" was leaking out instead of going down into the well."
There are some inconsistencies with this article.
There are no "Disks" or "Subsea safety structure" 1,000 feet below the sea floor, all that is there is well bore. There is nothing that can allow the mud or oil to "escape" into the rock formation outside the well bore except the well, because it is the only thing there.
All the actions and few tid bits of information all lead to one inescapable conclusion. The well pipes below the sea floor are broken and leaking. Now you have some real data of how BP's actions are evidence of that, as well as some murky statement from "BP officials" confirming the same.
I took some time to go into a bit of detail concerning the failure of Top Kill because this was a significant event. To those of us outside the real inside loop, yet still fairly knowledgeable, it was a major confirmation of what many feared. That the system below the sea floor has serious failures of varying magnitude in the complicated chain, and it is breaking down and it will continue to.
What does this mean?
It means they will never cap the gusher after the wellhead. They cannot...the more they try and restrict the oil gushing out the bop?...the more it will transfer to the leaks below. Just like a leaky garden hose with a nozzle on it. When you open up the nozzle?...it doesn't leak so bad, you close the nozzle?...it leaks real bad,
same dynamics. It is why they sawed the riser off...or tried to anyway...but they clipped it off, to relieve pressure on the leaks "down hole". I'm sure there was a bit of panic time after they crimp/pinched off the large riser pipe and the Diamond wire saw got stuck and failed...because that crimp diverted pressure and flow to the rupture down below.
Contrary to what most of us would think as logical to stop the oil mess, actually opening up the gushing well and making it gush more became direction BP took after confirming that there was a leak. In fact if you note their actions, that should become clear. They have shifted from stopping or restricting the gusher to opening it up and catching it. This only makes sense if they want to relieve pressure at the leak hidden down below the seabed.....and that sort of leak is one of the most dangerous and potentially damaging kind of leak there could be. It is also inaccessible which compounds our problems. There is no way to stop that leak from above, all they can do is relieve the pressure on it and the only way to do that right now is to open up the nozzle above and gush more oil into the gulf and hopefully catch it, which they have done, they just neglected to tell us why, gee thanks.
A down hole leak is dangerous and damaging for several reasons.
There will be erosion throughout the entire beat up, beat on and beat down remainder of the "system" including that inaccessible leak. The same erosion I spoke about in the first post is still present and has never stopped, cannot be stopped, is impossible to stop and will always be present in and acting on anything that is left which has crude oil "Product" rushing through it. There are abrasives still present, swirling flow will create hot spots of wear and this erosion is relentless and will always be present until eventually it wears away enough material to break it's way out. It will slowly eat the bop away especially at the now pinched off riser head and it will flow more and more. Perhaps BP can outrun or keep up with that out flow with various suckage methods for a period of time, but eventually the well will win that race, just how long that race will be?...no one really knows....However now?...there are other problems that a down hole leak will and must produce that will compound this already bad situation.
This down hole leak will undermine the foundation of the seabed in and around the well area. It also weakens the only thing holding up the massive Blow Out Preventer's immense bulk of 450 tons. In fact?...we are beginning to the results of the well's total integrity beginning to fail due to the undermining being caused by the leaking well bore.
The first layer of the sea floor in the gulf is mostly lose material of sand and silt. It doesn't hold up anything and isn't meant to, what holds the entire subsea system of the Bop in place is the well itself. The very large steel connectors of the initial well head "spud" stabbed in to the sea floor. The Bop literally sits on top of the pipe and never touches the sea bed, it wouldn't do anything in way of support if it did. After several tens of feet the seabed does begin to support the well connection laterally (side to side) you couldn't put a 450 ton piece of machinery on top of a 100' tall pipe "in the air" and subject it to the side loads caused by the ocean currents and expect it not to bend over...unless that pipe was very much larger than the machine itself, which you all can see it is not. The well's piping in comparison is actually very much smaller than the Blow Out Preventer and strong as it may be, it relies on some support from the seabed to function and not literally fall over...and it is now showing signs of doing just that....falling over.
If you have been watching the live feed cams you may have noticed that some of the ROVs are using an inclinometer...and inclinometer is an instrument that measures "Incline" or tilt. The BOP is not supposed to be tilting...and after the riser clip off operation it has begun to...
This is not the only problem that occurs due to erosion of the outer area of the well casings. The way a well casing assembly functions it that it is an assembly of different sized "tubes" that decrease in size as they go down. These tubes have a connection to each other that is not unlike a click or snap together locking action. After a certain length is assembled they are cemented around the ouside to the earth that the more rough drill hole is bored through in the well making process. A very well put together and simply explained process of "How to drill a deep water oil well" is available here:
The well bore casings rely on the support that is created by the cementing phase of well construction. Just like if you have many hands holding a pipe up you could put some weight on the top and the many hands could hold the pipe and the weight on top easily...but if there were no hands gripping and holding the pipe?...all the weight must be held up by the pipe alone. The series of connections between the sections of casings are not designed to hold up the immense weight of the BOP without all the "hands" that the cementing provides and they will eventually buckle and fail when stressed beyond their design limits.
These are clear and present dangers to the battered subsea safety structure (bop and lmrp) which is the only loose cork on this well we have left. The immediate (first 1,000 feet) of well structure that remains is now also undoubtedly compromised. However.....as bad as that is?...it is far from the only possible problems with this very problematic well. There were ongoing troubles with the entire process during the drilling of this well. There were also many comprises made by BP IMO which may have resulted in an overall weakened structure of the entire well system all the way to the bottom plug which is over 12,000 feet deep. Problems with the cementing procedure which was done by Haliburton and was deemed as “was against our best practices.” by a Haliburton employee on April 1st weeks before the well blew out. There is much more and I won't go into detail right now concerning the lower end of the well and the troubles encountered during the whole creation of this well and earlier "Well control" situations that were revieled in various internal BP e-mails. I will add several links to those documents and quotes from them below and for now, address the issues concerning the upper portion of the well and the region of the sea floor.
What is likely to happen now?
Well...none of what is likely to happen is good, in fact...it's about as bad as it gets. I am convinced the erosion and compromising of the entire system is accelerating and attacking more key structural areas of the well, the blow out preventer and surrounding strata holding it all up and together. This is evidenced by the tilt of the blow out preventer and the erosion which has exposed the well head connection. What eventually will happen is that the blow out preventer will literally tip over if they do not run supports to it as the currents push on it. I suspect they will run those supports as cables tied to anchors very soon, if they don't, they are inviting disaster that much sooner.
Eventually even that will be futile as the well casings cannot support the weight of the massive system above with out the cement bond to the earth and that bond is being eroded away. When enough is eroded away the casings will buckle and the BOP will collapse the well. If and when you begin to see oil and gas coming up around the well area from under the BOP? or the area around the well head connection and casing sinking more and more rapidly? ...it won't be too long after that the entire system fails. BP must be aware of this, they are mapping the sea floor sonically and that is not a mere exercise. Our Gov't must be well aware too, they just are not telling us.
All of these things lead to only one place, a fully wide open well bore directly to the oil deposit...after that, it goes into the realm of "the worst things you can think of" The well may come completely apart as the inner liners fail. There is still a very long drill string in the well, that could literally come flying out...as I said...all the worst things you can think of are a possibility, but the very least damaging outcome as bad as it is, is that we are stuck with a wide open gusher blowing out 150,000 barrels a day of raw oil or more. There isn't any "cap dome" or any other suck fixer device on earth that exists or could be built that will stop it from gushing out and doing more and more damage to the gulf. While at the same time also doing more damage to the well, making the chance of halting it with a kill from the bottom up less and less likely to work, which as it stands now?....is the only real chance we have left to stop it all.
It's a race now...a race to drill the relief wells and take our last chance at killing this monster before the whole weakened, wore out, blown out, leaking and failing system gives up it's last gasp in a horrific crescendo.
We are not even 2 months into it, barely half way by even optimistic estimates. The damage done by the leaked oil now is virtually immeasurable already and it will not get better, it can only get worse. No matter how much they can collect, there will still be thousands and thousands of gallons leaking out every minute, every hour of every day. We have 2 months left before the relief wells are even near in position and set up to take a kill shot and that is being optimistic as I said.
Over the next 2 months the mechanical situation also cannot improve, it can only get worse, getting better is an impossibility. While they may make some gains on collecting the leaked oil, the structural situation cannot heal itself. It will continue to erode and flow out more oil and eventually the inevitable collapse which cannot be stopped will happen. It is only a simple matter of who can "get there first"...us or the well.
We can only hope the race against that eventuality is one we can win, but my assessment I am sad to say is that we will not.
The system will collapse or fail substantially before we reach the finish line ahead of the well and the worst is yet to come.
Sorry to bring you that news, I know it is grim, but that is the way I see it....I sincerely hope I am wrong.
We need to prepare for the possibility of this blow out sending more oil into the gulf per week then what we already have now, because that is what a collapse of the system will cause. All the collection efforts that have captured oil will be erased in short order. The magnitude of this disaster will increase exponentially by the time we can do anything to halt it and our odds of actually even being able to halt it will go down.
The magnitude and impact of this disaster will eclipse anything we have known in our life times if the worst or even near worst happens...
We are seeing the puny forces of man vs the awesome forces of nature.
We are going to need some luck and a lot of effort to win...
and if nature decides we ought to lose, we will....

On April 1, a job log written by a Halliburton employee, Marvin Volek, warns that BP’s use of cement “was
against our best practices.”
An April 18 internal Halliburton memorandum indicates that Halliburton again warned BP about its practices,
this time saying that a “severe” gas flow problem would occur if the casings were not centered more carefully.
Around that same time, a BP document shows, company officials chose a type of casing with a greater risk of collapsing.
Mark Hafle, the BP drilling engineer who wrote plans for well casings and cement seals on the Deepwater
Horizon's well, testified that the well had lost thousands of barrels of mud at the bottom. But he said models
run onshore showed alterations to the cement program would resolve the issues, and when asked if a cement
failure allowed the well to "flow" gas and oil, he wouldn't capitulate.
Hafle said he made several changes to casing designs in the last few days before the well blew, including the
addition of the two casing liners that weren't part of the original well design because of problems where the
earthen sides of the well were "ballooning." He also worked with Halliburton engineers to design a plan for
sealing the well casings with cement.

BP Used Riskier Method to Seal Well Before Blast
There you have it folks. Information we here at the Alaska Progressive Review certainly trust more than that coming from BP or our CSA government (Corporate States of America). There are even more apocalyptic scenarios being discussed by other geologists, surmising that if the seafloor totally collapses around this well, and the entire vast highly pressurised methane/oil deposit is open to the sea, that tremendous quantities of methane gas would surface, accelerating global warming, and even posing a health hazard to people in the region! We only hope these are just worst-case surmises, and won't be the reality! Vaya con dios.
