re: #537 Stanley Sea

. .. I’m assuming all the other rigs have been approved for the same system of drilling no different than BP.

This is not correct.
Each drilling job is its own thing, with different formations, different depths, different drilling plans, everything.

Within a week after the disaster, my husband had a good idea of what had happened and why, and he was appalled, appalled, at the decisions BP made. He has drilled approx 250-300 wells; and has never once done things that way.
