O&G Logging Question

This is a question for some expert a person in the know...

I understand that a well/hole is logged whether it is a duster or a gusher and Im sure that different wells, different conditions takes a different length of time to log.

... but

If companies come across as a duster, do they normally say "F-ck it, lets do the bare minimum we have to cause it is costing us a kazillion dollars being here and we know we won't make money out it?"

... and

If companies come across a gusher, do they say "Lets log everything! (and take longer) so we get all the data we can for this mofo!"

and my final question really is... Can we use the time on location as an indicator of success? Even speculatively?
