According to the report, Halliburton, at the time the cement was pumped in to case the Macondo well, had the results of three tests that showed the formula was likely not up to the job of sealing oil from the well bore, and none that showed this batch would hold up. We should note that one test came back after the fact showing the cement would be OK, and that BP says it never conducted a test of the cement's stability.
