@6aue, same can be said for Noble stock. It was only a good deal prior to 2014, before all the Nobleoids heads grew too big. After that it was just another dead cat.
As for comments by @plg, LOL! What a load of garbage. "If you get a hold of true unmanipulated benchmarking data" you will discover nearly all of Noble's real high performers had left the company by the time Chevron acquired it. That includes ALL the major players responsible for Noble's successes at Aseng, Alen, Tamar, Leviathan, Niobrara, etc, etc, etc.
They either left on their own accord, because of all the cr-p that was being spewed (ask a legacy Noblite about GAP, one of those truly "useless initiatives that simply distract the workforce from working on things that actually make money") or they were driven out in repetitive purges by an inept management struggled to cope with the twin whammy of low oil prices and the realization that they really hadn't discovered "the secret sauce for success".
Bottomline: First, Noble isn't the example to follow for a better Chevron. Second, beware the legacy Noble type who "arrogantly" claims they have more substance in their big toe than you. They are one of the hanger-on az kissers that conned Noble management into thinking they were worth something. They aren't.
Don't get me wrong. I'm not blasting all the Legacy Noble people. The young ones in particular are innocents, victims really. And a few of the experienced people are decent. But the loud mouthed folks like @plg are just worthless.
PS: By now Chevron should have a good handle on all of Noble's... cough...cough... resource estimates. The downward revisions should help put @plg's comments in perspective.
