For your area it may be more difficult to find some than others, but I'll try to speak to what I know about each topic. Just about any drug manufacturing company will be able to give you the same initial experience and exposure to the field, and the same most likely goes for oil/petro. However what it comes to materials processing there are vastly different subfields. Different companies will specialize in metals, ceramics, polymers, or some combination of the three, all of which have very different manufacturing methods.
The best thing you can do is to apply to everything you possibly can, and take whatever you can get as soon as possible. That means summer internships at companies, on campus research work during the school year and also during the summer. If you have advisers for that sort of thing use them, they'll help you get some semblance of an idea of what to do. Do extracurriculars (preferably ones that show 'intelligence' like rocket club or something like that) to increase your chance of getting these jobs because when you start school you are basically not marketable at all and the slightest advantage can mean you get the job over other people. If, and hopefully when, you get something you'll be doing absolute grunt work like data crunching and basic lab prep, but the idea is it's a stepping stone onto having a more advanced position. You have four years to try things out, but if you wait too long you'll have just squandered your time, which a lot of people do, and can really fuck you if you don't know what you want to do exactly.
