Gulf Oil Update: Day 87

NEWS ALERT:

BP Closed all 5 Cap Valves Thursday afternoon: No oil is currently leaking from the well bore and new Cap assembly located above the level of the sea-bed during the integrity testing.

It is not clear at this time whether the well casing might be leaking below the level of the sea-bed since BP has not disclosed whether the pressure inside the well-bore is being maintained in the range necessary to prove that no leak exists anywhere in the system. This should be obvious in the next 24 hours perhaps sooner.

Retired Adm. Thad Allen indicated yesterday that the acoustic (ultrasonic) testing from several days ago did not disclose any abnormal pockets or collection of oil or methane gas outside the well bore (below the sea-bed and above the oil reservoir) in the geological formation. If true that is very good news.

NEWS BUlLETIN: BP Suspends Integrity Tests Wednesday PM after Obama Administration gave OK to proceed: Cap Assembly Has Leak


BP works to fix valve leak before choking oil flow

NEW ORLEANS (AP) -- BP engineers working to choke the flow of oil into the Gulf of Mexico found a leak on a line attached to the side of the new well cap and were trying to fix it Thursday before attempting to stop the crude.

BP said Wednesday evening it had isolated the leak and was repairing it before moving forward. It wasn't clear how it would affect the timing of the operation, or whether oil continued to be slowly closed off into the cap.

Work started earlier Wednesday after a day-long hiatus to allay government fears that the disaster could be made worse by going forward with the tests to determine whether the temporary cap can withstand the pressure and contain the oil. It was the best hope yet of stopping the crude from streaming into the water for the first time since the April 20 explosion on the Deepwater Horizon rig that killed 11 people.

The process began with BP shutting off pipes that were funneling some of the oil to ships on the surface so the full force of the gusher went up into the cap. Then deep-sea robots began slowly closing, one at a time, three openings in the cap that let oil pass through. Ultimately, the flow of crude will be blocked entirely.

All along, engineers were watching pressure readings to learn whether the well is intact. The first two valves shut off like a light switch, while the third works more like a dimmer and takes longer to close off.

The leak was found in the line attached to the dimmer switch, but live video footage showed that oil previously spewing from other sources on the cap remained closed off.

Retired Coast Guard Adm. Thad Allen, the Obama administration's point man on the disaster, said a committee of scientists and engineers will monitor the results and assess every six hours, and end the test after 48 hours to evaluate the findings.

"I was gung-ho for this test and I remain gung-ho for this test," he said Wednesday.

If the cap works, it will enable BP to stop the oil from gushing into the sea, either by holding all the oil inside the well machinery like a stopper or, if the pressure is too great, channeling some through lines to as many as four collection ships.

The cap - a 75-ton metal stack of lines and valves - was lowered onto the well on Monday in hopes of either bottling up the oil inside the well machinery, or capturing it and funneling it to the surface. But before BP could test the equipment, the government intervened because of concerns about whether the buildup of pressure from the gushing oil could rupture the walls of the well and make the leak worse.

"We sat long and hard about delaying the tests," Allen said. He said that the pause was necessary in the interest of the public, the environment and safety, until officials were convinced the test could go forward.

Allen said the testing will also offer insight into the other, more permanent solution to the fix: two relief wells intended to plug the gusher from deep underground. The mapping of the sea floor that was done to prepare for the well cap test and the pressure readings will also help them determine how much mud and cement will be needed to seal off the well.

Drill work was stopped on one relief well because it was not clear what effect the testing of the cap could have on it. Work on the other relief well had already been stopped according to plan. (Editor's bold emphasis throughout)

The government estimates 1.5 million to 2.5 million gallons are leaking every day.

The latest effort to control the gushing well follows a string of failed attempts by BP to contain the leak, including the use of a giant concrete-and-steel box that quickly became encased in ice-like crystals; a colossal siphon tube that trapped very little oil, and an effort to jam the well by pumping in mud and shredded rubber.

As of Wednesday, the 85th day of the disaster, between 92 million and 182 million gallons of oil had spewed into the Gulf since the rig leased by BP exploded.

Scientist Denies He Ever Predicted BP Oil Spill Would Cause Extinction Of Mankind

Businessinsider.com

Suddenly everyone's talking about the methane-driven oceanic eruption and mass extinction theories of Dr. Gregory Ryskin, claiming that elevated methane levels from the oil spill could cause the end of mankind.

Absent from this discussion has been Ryskin, who Northwestern University says is out of his office until September. The professor gave us the real story by email:

"I also want to emphasize that in my theory, methane hydrates (clathrates) do not play any role."

Methane hydrates are the volatile compounds that have been released in large quantities in the Gulf of Mexico. They may suffocate aquatic life or cause a pressure explosion. But they probably won't poison the atmosphere and destroy 96 percent of life on earth.

He was talking about "an extremely fast, explosive release of dissolved methane (and other dissolved gases...) that accumulated in the oceanic water masses." For more on Ryskin's methane theories, he said we should watch this video from 2007... For more See THIS... and THIS...

Gulf Oil Update: Day 86

Gulf Gusher To Keep Flowing As Cap Test Delayed

by The Associated Press
July 14, 2010




Oil emerges from the damage wellhead Tuesday morning in the Gulf of Mexico.

A pivotal moment in the Gulf oil crisis hit an unexpected snag Tuesday evening when officials announced they needed more time before they could begin choking off the geyser of crude at the bottom of the sea.

BP and federal officials did not say what prompted the decision or when the testing would begin on a new, tighter-fitting cap it had just installed on the blown-out well. The oil giant had been scheduled to start slowly shutting off valves on the 75-ton cap, aiming to stop the flow of oil for the first time in three months.

It seemed BP was on track to start the test Tuesday afternoon. The cap, lowered over the blown-out well Monday night, is designed to be a temporary fix until the well is plugged underground.

A series of methodical, preliminary steps were completed before progress stalled. Engineers spent hours on a seismic survey, creating a map of the rock under the sea floor to spot potential dangers, like gas pockets. It also provides a baseline to compare with later surveys during and after the test to see if the pressure on the well is causing underground problems.

An unstable area around the wellbore could create bigger problems if the leak continued elsewhere in the well after the cap valves were shut, experts said.

"It's an incredibly big concern," said Don Van Nieuwenhuise, director of Professional Geoscience Programs at the University of Houston. "They need to get a scan of where things are, that way when they do pressure testing, they know to look out for ruptures or changes."

It was unclear whether there was something in the results of the mapping that prompted officials to delay. Earlier, BP Vice President Kent Wells said he hadn't heard what the results were, but he felt "comfortable that they were good."

National Incident Commander Thad Allen met with the federal energy secretary and the head of the U.S. Geological Survey as well as BP officials and other scientists after the mapping was done.

"As a result of these discussions, we decided that the process may benefit from additional analysis," Allen said in a statement. He didn't specify what type of analysis would be done, but said work would continue until Wednesday.

Assuming BP gets the green light to do the cap testing after the extra analysis is finished, engineers can finally begin to shut the openings in the 75-ton metal stack of pipes and valves gradually, one at a time, while watching pressure gauges to see if the cap holds or any new leaks erupt.

The operation could last anywhere from six to 48 hours.

If the cap works, it will enable BP to stop the oil from gushing into the sea, either by holding all the oil inside the well machinery like a stopper or, if the pressure is too great, channeling some through pipes to as many as four collection ships.

Along the Gulf Coast, where the spill has heavily damaged the region's vital tourism and fishing industries, people anxiously awaited the outcome of the painstakingly slow work.

"I don't know what's taking them so long. I just hope they take care of it," said Lanette Eder, a vacationing school nutritionist from Hoschton, Ga., who was walking on the white sand at Pensacola Beach, Fla.

"I can't say that I'm optimistic - It's been, what, 84 days now? - but I'm hopeful," said Nancy LaNasa, 56, who runs a yoga center in Pensacola.

The cap is just a stopgap measure. To end the leak for good, the well needs to be plugged at the source. BP is drilling two relief wells through the seafloor to reach the broken well, possibly by late July, and jam it permanently with heavy drilling mud and cement. After that, the Gulf Coast faces a long cleanup.

In Washington, White House spokesman Robert Gibbs said the effort to put the containment cap into operation "represents the best news that we've had in the preceding 85 days."

"We are approaching what we hope is the next phase in the Gulf - understanding that that next phase is likely to take many years," he added.

BP engineers planned to shut off pipes that are already funneling some oil to two ships, to see how the cap handles the pressure of the crude coming up from the ground. Then they planned to close, one by one, three valves that let oil pass through the cap.

Experts said stopping the oil too quickly could blow the cap off or further damage the well.

Scientists will be looking for high pressure readings of 8,000 to 9,000 pounds per square inch. Anything lower than 6,000 might indicate previously unidentified leaks in the well.

"What we can't tell is the current condition of the wellbore below the seafloor," Allen said. "That is the purpose of the well integrity test."

If the cap cannot handle the pressure, or leaks are found, BP will have to reopen the valves and let some of the oil out. In that case, BP is ready to collect the crude by piping it to as many as four vessels on the surface.

The leak began after the Deepwater Horizon offshore drilling platform exploded on April 20, killing 11 workers. As of Tuesday, the 84th day of the disaster, between 90.4 and 178.6 million gallons of oil had spewed into the Gulf.

BP delays tests on Cap: No reason given




Critical NEWS Update: 11:39 am 7/14/10

The results of acoustic (ultrasonography) tests performed on the geological formation in and around the Macondo Well yesterday July 13, 2010 have not been disclosed. Within the past hour, BP has announced that it has ceased drlling both of the "relief wells." This is either very good or extremely bad news. It may be that they have discovered the presence of multiple leaking channels below the sea-bed eminating from defects in the well casing suggesting that the relief wells will be unable to seal/kill the well.

More optimistically, it may be that BP has discovered that it will be unnecesary to use either of the relief wells because it will be able to successfully seal the well utilizing the new cap. The latter option seems unlikely however.

In any case, it is extremely odd that BP would simply cease drilling on both of the relief wells while they are supposedly analyzing the data.

This Can't Be Good: BP Delays Pressure Tests and Stops Drilling Relief Well

Only Bad News on the Oil Spill Today

After some good news in the past couple of days, BP is going back to what it has accustomed us to over the past few months: bad news. The first of these is that despite the fact that the cap has been fitted over the oil leak, the pressure tests to determine if the leak can be completely captured by this new 'top hat' will have to wait for "further analysis" (this was decided after a meeting with Steven Chu and his team of advisers). The second piece of bad news has to do with the relief well, and when you put the two together, it's enough to worry...

Relief Well Drilling Stopped for "Up to 48 Hours"

BP said this morning that they were halting the drilling of the relief well - the second well that will connect with the leaking one deep underground and permanently plug the leak - for "up to 48 hours" and didn't explain this decision. Chances are it's simply to avoid contaminating seismic readings around the well, but it could also be a sign of bigger troubles. In any case, this delay means that whatever else happens in the meantime, the relief well will be completed later than it would have been otherwise.

What Could This Mean?

What's scary about this is the possibility that this suspension of operations for "further analysis" might mean that they found something really bad, and they're now making sure before going public with it. After all, the relief well is still a few weeks from being completed, so it's safe to assume that it isn't too close to the leaking well. If they're stopping drilling now, this could mean that they're afraid that the integrity of the well was severely compromised under the surface. Could this mean that the relief well won't be able to 'connect' with the leaking well as easily as first thought? Or at all? Or do they have to change their approach, causing further delays and allowing more oil to leak in the Gulf? These are scary possibilities.

Let's hope that these delays are in fact caused by minor problems and that the pressure tests will soon begin and succeed, and that the relief well will be able to plug the leak once and for all.

Meanwhile...
At this time, the oil is still gushing out of the leak, going into the Gulf of Mexico


Editor's NOTE:

Mr. John Hoffmeister, former CEO for Shell Oil was interviewed on "Hardball" with Chris Matthews this afternoon regarding the significance of the above developments. He confirmed that Secretary of Energy Steven Chu and a team of independent scientists/analysts had asked BP not to proceed with testing the new Cap by subjecting it to increasing amounts of pressure as BP had planned. Chu et al. are apparently concerned that not enough is known about whether the tests themselves might cause damage in the sub-sea surface of the well casing.

Hoffmeister again repeated his previous comment that many experts in the petroleum industry fear that the well-casing is badly damaged below the level of the sea bed which would complicate the attempt to seal/kill the Mocondo well utilizing the relief well(s) perhaps rendering it impossible. He agrees with the current plan to evaluate the situation more fully before proceeding. In addition, he recommended not testing the pressure until at least one of the relief wells is finished.

Gulf Oil Update: Day 85

Gulf Oil Spill - Gutsy Solution Restores Environment in Just Six Weeks!!!

The Texas Land Office and Texas Water Commission successfully used 'oil eating' microbes to clean up large oil spills in just weeks. Microbes hunt down and eat the toxic oil and leave only a biodegradable waste that is non-toxic to humans and marine life. Marshland and beaches were pristine again in just weeks---not years like the Exxon Valdez spill. This is the answer to save the seafood industry and all the precious creatures we are about to kill. Watch this YouTube Video and see how effective Microbes work!



Editor's NOTE:

The "oil-eating" microbe idea would seem to provide great promise if the results reported in the above video are true and can be repeated by scientists. The Obama administration should immediately conduct appropriate scientific tests and begin employing microbes ASAP if the tests are successful--whether BP is in agreement or not.

If the latest reports are true that BP has managed to place a new cap on the riser pipe which can all but completely stop the flow of oil until the relief wells are finished, the microbe technology would seem to offer the quickest and most efficient way of clearing the millions of barrels of oil which have already spilled into the Gulf of Mexico. The government should order BP to cease using toxic disbursants (prarticularly Corexit) the use of which make it more difficult for microbes to clear oil throughout the entire water column.

All readers are encouraged to spread the word far and wide to media, Congress, the Obama administration and any other interested parties.

BP prepares to test new cap installed on oil leak


AP – In this image taken from video provided by BP PLC at 18:23 CDT, a new containment cap, top, is lowered …

By COLLEEN LONG and HARRY R. WEBER, Associated Press Writers Colleen Long And Harry R. Weber, Associated Press Writers

NEW ORLEANS – After securing a new, tight-fitting cap on top of the leaking well in the Gulf of Mexico, BP prepared Tuesday to begin tests to see if it will hold and stop fresh oil from polluting the waters for the first time in nearly three months.

The oil giant expects to know within 48 hours if the new cap, which landed Monday after almost three days of painstaking, around-the-clock work a mile below the Gulf's surface, can stanch the flow. The solution is only temporary, but it offers the best hope yet for cutting off the gush of billowing brown oil.

The cap's installation was good news to weary Gulf Coast residents who have warily waited for BP to make good on its promise to clean up the mess. Still, they warned that even if the oil is stopped, the consequences are far from over.

"I think we're going to see oil out in the Gulf of Mexico, roaming around, taking shots at us, for the next year, maybe two," Billy Nungesser, president of Louisiana's oil-stained Plaquemines Parish, said Monday. "If you told me today no more oil was coming ashore, we've still got a massive cleanup ahead."

Starting Tuesday, the cap will be tested and monitored to see if it can withstand pressure from the gushing oil and gas. The tests could last anywhere between six to 48 hours, according to National Incident Commander Thad Allen.

The cap will be tested by closing off three separate valves that fit together snugly, choking off the oil from entering the Gulf. BP expects no oil will be released into the ocean during the tests, but remained cautious about the success of the system.

"This will not however be an indication that flow from the wellbore has been permanently stopped," the company said in a statement. "The sealing cap system never before has been deployed at these depths or under these conditions, and its efficiency and ability to contain the oil and gas cannot be assured."

BP will be watching pressure readings. High pressure is good, because it would mean the leak has been contained inside the wellhead machinery. But if readings are lower than expected, that could mean there is another leak elsewhere in the well.

Even if the cap works, the blown-out well must still be plugged. A permanent fix will have to wait until one of two relief wells being drilled reaches the broken well, which will then be plugged up with drilling mud and cement. That may not happen until mid-August.

Even if the flow of oil is choked off while BP works on a permanent fix, the spill has already damaged everything from beach tourism to the fishing industry.

Tony Wood, director of the National Spill Control School at Texas A&M-Corpus Christi said the sloppiest of the oil — mousse-like brown stuff that has not yet broken down — will keep washing ashore for several months, with the volume slowly decreasing over time.

He added that hardened tar balls could keep hitting beaches and marshes each time a major storm rolls through for a year or more. Those tar balls are likely trapped for now in the surf zone, gathering behind sand bars just like sea shells.

"It will still be getting on people's feet on the beaches probably a year or two from now," Wood said.

But on Monday, the region absorbed a rare piece of good news in the placement of the 150,000-pound cap on top of the gushing leak responsible for so much misery.

Around 6:30 p.m. CDT, live video streams trained on the wellhead showed the cap being slowly lowered into place. BP officials said the device was attached around 7 p.m.

"I'm very hopeful that this cap works and we wake up in the morning and they're catching all the oil. I would be the happiest person around here," said Mitch Jurisich, a third generation oysterman from Empire, La., who has been out of work for weeks.

Residents skeptical BP can deliver on its promise to control the spill greeted the news cautiously.

"There's no telling what those crazy suckers are going to do now," Ronnie Kenniar said when he heard the cap was placed on the well. The 49-year-old fishermen is now working for BP in the Vessel of Opportunity program, a BP-run operation employing boat owners for odd jobs.

James Pelas, 41, a shrimper who took a break from working on his boat at a marina in Venice, La., said he didn't think the crisis would be over for a long time.

"I ain't excited about it until it's closed off completely," he said. "Oil's scattered all over the place."

Meanwhile, the Obama administration issued a revised moratorium on deep-water offshore drilling Monday to replace the one that was struck down by the courts as heavy-handed. The new ban, in effect until Nov. 30, does not appear to deviate much from the original moratorium, as it still targets deep-water drilling operators while defining them in a different way.

As of Monday, the 83rd day of the disaster, between 89 million and 176 million gallons of oil had poured into the Gulf, according to government estimates. The spill started April 20 when the Deepwater Horizon rig, leased by BP from Transocean Ltd, exploded and burned, killing 11 workers. It sank two days later.

NYT: Yes, BP Could Go Into Bankruptcy

By: David Dayen
Sunday July 11, 2010 6:30 am
Firedoglake.com

At almost every step of the way, BP’s efforts to cap the well spewing oil into the Gulf have wound up making things worse. Let’s hope this doesn’t continue, but for now, we have an uncapped well putting at least 35,000 barrels and maybe as much as 100,000 into the water today (I don’t know why WaPo is foregrounding the 15,000 barrels the last containment dome was catching, implying that no more oil would flow). You can read BP’s entire plan for the next several weeks, both the new cap and the timeline for the relief wells, in this letter to Thad Allen.

While BP claims that the project is moving on schedule, they’ve said that before, and yet previous top hats, top kills and junk shots wound up failing or capturing an inadequate amount of oil to stop the leak. And if the well cannot be fully capped, the risk of an increased flow into the Gulf exists. Remember that every barrel of oil carries with it not only a human cost in pollution, but a hard financial cost in per-barrel fines and penalties. I’ve been saying for a month that BP stands at risk of bankruptcy, and the New York Times picks it up today:

With pockets as deep as BP’s — its assets are worth more than $260 billion — the possibility that it might be forced to seek bankruptcy protection because of the Gulf of Mexico oil spill is considered remote by many industry experts.

But what if the company’s plan to contain the spill in the next several days does not work, and other efforts to stop the gushing oil also fail? If that were to occur, the worst-case projections of some experts, if they came to pass, would strain the ability of any company to pay, said Robin K. Craig, associate dean for environmental programs at the Florida State University College of Law.

Professor Craig said that if the oil hit the Gulf Stream and was carried by currents to East Coast states, Cuba and other Caribbean nations, and possibly even Britain, lawsuits could quickly mount to levels even BP could not handle.

“My bet is that BP will finally go bankrupt from the tort liability and the environmental liability,” she said. “Hypothetically, a bluefin tuna farmer in the Mediterranean could end up with a claim against BP.”


This becomes particularly true if Eric Holder does pursue legitimate criminal charges. Holder has said that his wide-ranging investigation would cover more companies than BP, but obviously they would be at the center of any investigation. And those other companies have already begun to stiff BP, which will result in additional legal proceedings (Anadarko may even have a case that BP holds all the negligence in this case).

I know that BP has $260 billion in assets, and makes enough in a day to cover the entire $75 million liability cap (which doesn’t include criminal penalties). But this possibility is real. A lot of things would have to go wrong, but a lot have already. And while the executives at BP would probably emerge from bankruptcy without much trouble, you cannot say the same for the federal government, which would then be on the hook for much of the cleanup and damage awards.

Still, you’d have to sell off a LOT of assets before we get to that point.
