Even if Rig Hands had access to all the logs they would not know what to do with it. BUT rig hands do know what the bit pressure is and what they are seeing coming back in the mud pits. While they cannot tell you everything regarding the well (size, recoverability, etc.) they do have a good idea of the quality of a reservoir. They also talk with the "Company Man". A drilling rig (especially an offshore rig) is a like a small town. Everybody knows everybody's business. If the Company engineer gets excited then they know it.
I have been on too many rigs, we know when we hit a duster and we know when we hit something signicant.
