SAN ANTONIO, June 22 (UPI) -- A report by drilling contractor Transocean faults BP and Halliburton for underestimating the risk of a blowout on the Deepwater Horizon oil rig last year.
Transocean concluded the blowout preventer on the rig was adequately maintained but was never able to completely seal the well which spewed crude oil into the Gulf of Mexico from April 20 until July 15, 2010. The well was declared sealed Sept. 19.
