Contractor Halliburton knew the cement it used to seal the BP Deepwater oil rig was faulty but used it anyway, according to a report released by a federal commision. “Halliburton and BP both had results in March showing that a very similar foam slurry design to the one actually pumped at the Macondo well would be unstable, but neither acted upon that data,” according to investigators.
Thomas Roth, Halliburton’s vice-president of cementing, recently stated that his company’s tests showed the materials had “good stability,” a claim contradicted by BP officials.
Just who is to blame for the disaster?
