It depends on what refinery you are assigned to. Some days you won't leave the office, some days you'll be in the field all day. Day to day is always different, and that was what made the job so great. There will be a variety of different projects that will need a different set of solutions. I would say its about 60/40 office to field work.
Expect to look over and mark up various drawings such as One-Lines, P&ID's, Wiring schematics, etc.
You will talk with vendors and various other groups within the company to figure out the scope of your project.
You will learn a lot, but you shouldn't be intimidated as everyone I met was very understanding and informative. No one will expect you to know everything, just go into it with a desire to learn.
