Oil/Gas help

[centaur21]

I work for an oil/gas consulting company and have been thrown into the fire. As many of you know, the things learned in school don't help much when starting a new job fresh out of college. Anyway, I am to check one line and elevation diagrams against MCC vendor drawings for unclear logic or things that might be questioned when used out in the field. Basically what I am trying to do is make the drawings as clear as possible to anyone using them out in the field.

Does anyone know of examples of using one lines and elevation diagrams somewhere online? I know this question is broad, but I am trying to get up to speed as quickly as possible. THANKS!!
