Independent tests conducted for the commission by Chevron on a nearly identical mixture were also released Thursday. The results conclude the cement mix was unstable, raising questions about the validity of Halliburton's final test.
I find the technical aspects of the article interesting.
But one question remains: they should have had a tested cement for plugging such a deepwater well.
Were they trying to test a new cement in an unsafe environment? The article does not give enough information to say. Probably FreeRepublic Poster Thackney has an opinion...
Maybe Obama trying to blame the oil companies...
The results of the four tests were not shared with British Petroleum before the oil spill.
From the article, it is unclear if management at Halliburton had analyzed the results of the four tests before the oil spill.
Halliburton Shares Crash on Cement Test
Snippet..
Shares of Halliburton(HAL_) dropped by as much as 10% on Thursday afternoon after a presidential commission revealed that tests conducted before the BP Macondo oil spill showed that cement used by Halliburton were liable to create unstable conditions.
The presidential commission said Halliburton did not send any alarm signals to BP, though Halliburton did communicate the results of cement tests. The commission also stressed that BP’s full knowledge of the cement problems is still unknown.

Didn’t reports tell our government something was up on 9/11 but they all said it did not say airplanes and NY so how could we know???
Haliburton's use of nitrogen injected cement did not do so well in the early 80's on high pressure gas wells (on shore)...tended to blow out of the hole and cover the rig & location.
A two stage cementing job was the thing back then.
Nearly?? in concrete testing?? Thinking back....I'm thinking "temperature problem"...
