Technician challenges BP's claims on key devices
A technician is challenging BP's claim about how long it would have taken to install an additional number of a key device the oil giant had been warned was essential to prevent a significant gas flow problem in its well that later blew out.
Centralizers make sure the casing is running down the center of the well bore. If the casing is cemented off-center, there is a risk of an imperfect seal that could allow oil and gas to escape.
BP installed only six, against a Halliburton recommendation to install 21.
A BP well team leader asserted it would take 10 hours to install the additional 15. But technician Daniel Oldfather told a federal investigative panel today it would have taken him only four to eight hours to do the job.
