re: Sad news --- Oklahoma rig explosion leaves 5 missing

Read a report this morning that 3/5 were Patterson employees, so I'm guessing one of the two was a DD and either MWD or Company Man?

I worked around that area for a while. Those wells were very low pressure and pretty tricky when it came to mud losses, and then ballooning once you were tripping out of the hole. Regardless it seems crazy that no one noticed anything over a ~ 13,000' trip out of the hole. Especially considering it supposedly happened at 9 AM and even if they were short-staffed everyone would have had time to do their morning checks. FYI I'd never seen a rig that wasn't staffed with at least one mud engineer in the area.

Just a terrible situation, I guess the part that bugs me the most is the people that are most likely to die in that scenario(floorhands) are the ones least likely to know anything or have any sort of control in preventing what caused it.
