In its latest effort to spread the love from its Worst Company In America victory, BP has accused another much-loathed business, Halliburton, of destroying internal test results which BP claims demonstrates that the cement used to secure the ill-fated Gulf of Mexico oil well was unstable.

The claims are part of a 310-page filing by BP with the federal district court in New Orleans that is overseeing the class-action suit over the failure of the well and subsequent explosion of the Deepwater Horizon platform that killed 11 and spewed countless gallons of oil into the Gulf in 2010.

Halliburton has maintained that the cement mix used at the site was stable, but BP says the company has refused to turn over internal Halliburton test results that show that the slurry was not stable and may have broken down after being applied at the Macondo well, allowing hydrocarbons to flow through channels to the surface.

“Halliburton intentionally destroyed the evidence related to its non-privileged cement testing, in part because it wanted to eliminate any risk that this evidence would be used against it at trial,” BP said in the filing.

Of course, this comes only a couple months after Halliburton pointed the finger at BP for allegedly hiding information about the well that it claims may have prevented the disaster.
