Admission of the Gulf of Halliburton oil spills: critical test ignored deep horizon before BP Oil Spill

WASHINGTON - Halliburton co. recognized ignored a critical test on the final wording of the cement to seal before BP oil wells he blew in the Gulf of the Mexico disabling.

Society, which was entrepreneur cementation of BP, came under increased scrutiny when President oil spill commission investigators revealed Thursday that tests conducted by the company before the fatal eruption had shown the cement is unstable.

Halliburton in a statement issued late Thursday night said that he has not taken a test of stability on the final mixture of cement after modifying a last minute by BP has added more than some a prior statements by the company ingrédient.Les told tests showed cement is stable.

Failure of mixing cement to prevent oil and gas from entering the pit was identified by BP and others as one of the causes of the accident, the largest oil spill in the history of the United States.

BP and Halliburton decided to use a foam created by injection of nitrogen in cement grout to secure the bottom of the well, an outside expert decision criticized.

The Panel said Thursday that four tests conducted in February and April by Halliburton, only - last - had shown tiendrait.Mais mixing this unique success test results were shared with BP and perhaps not reached Halliburton, until the cement is pumped, according to a letter sent Thursday by Chief Fred h. Bartlit. investigative counsel Commissioners.

Halliburton said Thursday that success criterion was made on a different mixture of used subsequently.While some tests were conducted on the new wording requested by BP, these tests did not include a test of stability of foam, the company said.

According to the Commission, BP at the time of the eruption had only one test - results an analysis of sent February BP by Halliburton in March 8 that cement could échouer.Le tested slurry email in this case was a slightly different mix and requires a slightly different design, but there was no evidence that Halliburton reported the problem to BP or BP had concerns, said in the letter.

"Halliburton (and perhaps BP) should take account redesign of foam slurry before it pumping wells Macondo," wrote Bartlit.

Independent tests carried out for the commission by Chevron on an almost identical mixture jeudi.Les results have been published have concluded that the mixing of cement was unstable, raising questions about the validity of the test of Halliburton, showing that nearly final mixing was stable.The company said "differences" between its internal tests and the commission was caused by the use of different materials.

BP in the internal survey also conducted independent tests showed the cement mixture was wrong, but his analysis too has been criticized by Halliburton, who said that he is not formula correcte.Rapport PMO also mention testing cement Halliburton mid-April, but it seems BP the results obtained after the accident and considered its imperfect methods.

However, the commission obtained proprietary additives the Halliburton as well as a recipe to recreate the mud used on the shaft.Litres and a half of the real mixture used on the rig remain, but he is detained as evidence in criminal and civil investigations.

Halliburton has rejected requests for the commission that the February tests were conducted on a cement which was similar to that used.

"Contrary to the letter... tested in February manure does was not 'a design very similar to foam slurry actually pumped'", bed déclaration.La society has also said there are significant differences in the way in which the cement has been tested.

Actions Halliburton has dropped nearly $ 34 to below $ 30 in New York in the half-hour after the commission has published its conclusions.Les shares recovered a little and closed at $31.68 $2.74 or 8 percent.BP shares rose $ 40.38 to $41.28, and then quickly reversed course and fell to $40.28 .the shares finished trading with a gain of $49 cents to 40.59.

Independent researchers do not deal with other decisions that could have helped cement failure and possible rash, such as BP decision to use less centralizers recommended by Halliburton.Centreurs SID.Please you as well pipe is centered within the well cement bond properly.

BP has also been criticized for not bind cement for a long time, a test that checks after the cement is pumped down if sécurisé.Il are also questions about whether pumped down BP enough cement to complete the bottom of the well, which was more than three miles under the sea level.

Guest post: Gulf Oil Spill... mission accomplished or ongoing crisis?

→ Washington Blog

Media companies have stopped almost entirely covering the Gulf oil spill.

Many tried to say that the effects of the spill are far from being as bad as feared, and everything what is fairly well cleaned place and back to normal.

But today, it is generally reported that there is currently massive extends weathered petroleum spotted in the Gulf of the Mexico.

And as Oil Spill Law (FOSL) Florida websites tirelessly reported on the Gulf oil spill this all the time.

To give an example of the crisis underway in the Gulf, this is a gathering of some of the stories high top FOSL 3 days:

In related news, Government - always willing to go immediately to the bottom of what is happening really about and know perfectly the results - then sent crucial Gulf samples for analysis in a laboratory... Poland (u.s. laboratories are apparently occupied test toxicity hinky, mortgage mortgage saved titles, app and CDS naked) .and the result will be shipped by slow boat: NOAA does not wait for results back to the end of the year.

Peter Lehner: Six months after the spill, that we must always do to prevent another disaster

Error deserializing body of reply message for operation 'Translate'. The maximum string content length quota (8192) has been exceeded while reading XML data. This quota may be increased by changing the MaxStringContentLength property on the XmlDictionaryReaderQuotas object used when creating the XML reader. Line 1, position 9200.

It was six months ago that the Deepwater Horizon rig exploded, killing 11 men and sending 200 million gallons of oil into the Gulf of Mexico.The blast continues to reverberate half a year later.

Up to 50 percent of the oil may still remain in the Gulf, fishermen are still out of work or uncertain if their catch is safe, and the marine ecosystem is still degraded.

Yet, what is even more alarming is that America is in danger of repeating this tragedy.

Six months after the largest peacetime oil spill in history, we have failed to take the steps that would best prevent another devastating spill. ?While the federal government has made progress by issuing new safety standard, Congress should be moving right now to make drilling safer.

After all, the laws on the books are the same, America's level of oil consumption is the same, and our scientific understanding of oil spills is largely the same as before the BP blowout.

We can't keep doing nearly everything the same and expect different results. As actor Edward James Olmos said in an ad about the spill for NRDC's Action Fund, that is the definition of loco."It's time to boost our sanity," Olmos says. "America doesn't want more oil disasters."

Instead, Americans want Congress to make necessary changes. They support efforts to restore the Gulf and hold accountable BP.They also support efforts to transform the failed energy policies that fuel risky drilling. According to a poll conducted by the NRDC Action Fund, voters overwhelmingly support clean-energy legislation that creates jobs and climate-change pollution limits.

We know what it takes to protect coastal communities and marine life from devastating oil spills. We just need to start now, and this is how we begin.

Pass the Oil Spill Bill to Reform Offshore Drilling

Operating at the frontier of knowledge in conditions more challenging than deep space, wells like BP's are inherently dangerous.To make matters worse, the drive into deeper and riskier Gulf waters occurred in a context in which our watchdog agencies were defanged and compromised, creating an atmosphere in which oil-company engineers sometimes penciled in their own responses to inspection forms.

This reckless wildcatting and lax regulatory culture has to end. The Department of Interior issued new regulations - with more to follow - that will begin to make needed changes, but Congress must act as well. Only Congress has the power to strengthen the statutes that govern offshore drilling and hold companies fully accountable for damages.The House passed a bill promising in August, but the Senate went home for elections without passing key legislation to prevent this kind of disaster from happening again. Click here to tell your lawmakers to pass legislation spill as soon as they return in mid-November.

Respond to Immediate Health Concerns

Introducing 200 million gallons of oil into an environment has serious implications for people's health. Yet government testing of seafood and worker safety has been woefully inadequate and much of the data has been withheld from the public. The FDA should fix their flawed seafood testing, and the government should launch studies of residents' ongoing health effects.

Conduct Independent Scientific Research

Time and again, America has failed to conduct thorough research after oil spills.We can't afford to lose another opportunity to learn how to prevent and prepare for future spills.BP has committed to funding $500 million over 10 years into independent research, but that's only a fraction of what's needed.Meanwhile, the BP money is going to be distributed in a way that may put Gulf state's political interests ahead of scientific expertise.

Science should not fall victim to local politics.As I wrote in a recent letter to BP's CEO, the research money must get into the hands of the best scientists in the world, not just those who live in the Gulf.

Unleash Technologies that Help Us Use Oil More Efficiently

America's 800 million-gallon-a-day oil habit has encouraged energy companies to push past the limits of safe and reliable drilling.We burn oil in outdated engines as if it Katherine ain't one of the most valuable resources we have, and we turn a blind eye to the dangers involved in filling our tanks.

We should use oil as efficiently as we possibly can.As I explain in my new book, In Deep Water: The Anatomy of a Disaster, the Fate of the Gulf, and How to end our Oil Addiction, technologies exist today that can help us do that, but we need smart policies to make efficiency the norm instead of the exception.Last month, Obama administration officials said they are considering issuing fuel efficiency standards for cars and trucks equivalent to at least 47 miles per gallon and as high as 62 gallons by 2025.Setting the bar on the high end of this range will save 80 percent more oil than setting it at the low end.We are urging the administration to go high - a move that will save American families and American businesses money on fuel.

Together with more investment in public transit and low-carbon fuel options and a concerted effort to shift our freight transfer from trucks to rail and to design our communities so we are not sitting in traffic, America can cut our dependence on oil in half, create jobs for American workers, and better protect natural treasures like the Gulf of Mexico.
