A key what causes the most serious in the history of the United States Marine oil spill is preparing for the federal report revealed, BP made key mistakes, and not tell its partners and the governments of the United States, when it realized it as early as Wednesday.
The United States coast guard and institutions supervision offshore drilling held a hearing on April 20, 2010, deep water horizon tragedy in a year after an investigation team. BaoAnTing sea ocean energy management regulation and enforcement bureau has been top of the most detailed.
Other surveys by the management personnel, fault and rig crew engineer of the key data misreading, the bop's fault, to stop the oil flow into the sea, shortcomings.
At the same time, the interviews and the Associated Press obtained documents show a BP's scientists have found the combustible gas before the report of an oil in the gulf of Mexico deposit may play a role, but oil giant revealed no government survey found that as long as a year.
Although the engineering experts of gas sand two feet wide by large sections of the different levels of the disaster, a finding that caused further legal and financial problems on BP ghost. It can also improve the billions of dollars in case involves the company between concern.
"This is a key factor, in be found here hydrocarbons, rice university engineering professor what Ethiopia's southern gaza Nagarajaiah said." "I think, further studies are needed to determine what is how to reaction is BP, if they know that launched the facts."
Two months ago, BP rock physicists and LinNa Skripnikova participate in litigation lawyers say oil leakage seems to be a BP told the shallow water and mineral management service contractors and supervision of more than 300 feet above gas zone.
Because it gives a company needs to pump, good seal many cement, oil and natural gas drilling in the depth of the key parameters. Federal regulations require above 500 feet above the cement of hydrocarbons, BP held in the shallow cement assignments may is far lower than it should have.
Cement contractor harry burton company recently on BP a lawsuit, claiming that Skripnikova statements prove oil giant know a shallow gas before the explosion, should seek a new cement, and the design. BP has denied the allegations.
Participate in the work of Skripnikova from BP's MaKong more analysis the data to determine the depth of the reserves of oil and gas and characteristics, and this is a process, when Wells is sealed, so they can be used for production to give up the use of temporarily.
The initial information, and on the basis of the approval of the department of prison pipe BP plans to seal, placed in about 17300 feet below the surface of the water at the top of the cement. On April 19, the day before the explosion, cement pump. But Skripnikova said, she immediately, she and others from the rig explosion, the analysis to look one day she found a shallow gas reservoirs. This means that the cement has been placed in slightly below the surface of the water below 17000 feet.
She said she didn't relay information into deep water horizon, the engineer and warned they delayed to give up. She is in her deposition, she thinks that advice information transmission chain. BP has had more than $600000, and the budget of the point of operation and stop a new cement design means costs to 1 million of thousands of extra dollars.
Later in the deposition, Skripnikova back and said, the new analysis is not belong to her group discussion, until after the explosion, day.
Skripnikova never questioned the former President of the oil leak committee appointed public hearing. She also questioned before the coast guard BOEMRE American joint investigation team. Her name and her information is released in September last year of the internal investigation report BP.
BP spokesman Dean (Dean) holds to st1 Tuesday in a statement before the accident, evaluation, the AP top cement demand, BP oil or natural gas bearing no sure the problem area. Dean said: "BP provide materials about the region, across the region and the government investigation. The parties litigation"
BP said it provided a letter, it sent oil leakage committee October 30, 2010, after the explosion of six months, late on Tuesday. The letter said, BP will send the report of the committee, the draft to the company and the more detailed research to help inform its efforts, to stop the oil flow into the sea. Letter no detailed report said, what kind of data, or provide data are Skripnikova in her deposition discuss the same.
A report released by the disaster, and for a few months after a month ago, the President of the dissolution of an oil commission, investigators told the Associated Press, BP no specific in the group, said the investigation process may QiOu. The researchers, who did not wish to be named because he didn't speak, are authorized to speak publicly, said an independent rock physicists review team to provide the data, and not worried about more shallow gas in depth.
