WASHINGTON (AP) - Halliburton has acknowleded that it skipped a critical test on their cement formula. The cement was used to seal the BP oil well that blew out in the Gulf of Mexico.
Halliburton was was Brtitish Petroleum's cementing contractor. Officials say that BP at the last-minute increased the amount of a critical ingredient in the cement mix. However, an earlier test showed the cement was stable,and the company never performed a stability test on the new blend.
The cement's failure to prevent oil and gas from entering the well has been identified as one of the causes of the April 20 disaster.
