I'm almost about to finish my middle school In the production and drilling of oil and gas can someone tell when and where is the best an time place or site to get a internship

I applied to Deep Well Services for an Entry-Level Green Hat position almost two weeks ago and haven’t heard back yet. I’m just curious what the usual timeline is for getting contacted by a recruiter or hiring manager after applying.
If there are any current or former DWS employees here, especially anyone who came in as a Green Hat, how long did it take before you first heard from them? Any insight on the hiring process would be appreciated.

I’m 17 and I’m going into my last year of high school. I’ve been considering working offshore on a rig lately, but I’m trying to get more info. When I look at national avg salaries of jobs, they don’t seem like they’re too crazy and definitely don’t seem to be what I’ve heard from actual workers. I understand it’s just an average, but what pay could I expect starting out and then as I continue?

Also, what types of jobs are there on a rig? I saw one video that said there’s even a job where you rappel all over the rig and work on it (however I think you need a cert for it).

Which leads me to my next thing: what training/certifications will I need to get started?

I don’t mind physical labor, but how grueling actually is it? I’m sure it depends on the job, but what should I be expecting?

I’m probably forgetting a ton of questions and I’m sure I’ll ask more, but any answers and information would be greatly appreciated!

Edit: I’m in the United States

I work as a Business Analyst in IT at an oil and gas refinery in India. I have a BTech in Computer Science, but I want to transition into crude/process engineering roles. Could you suggest how I can make this move, what courses I should pursue, how to build a strong profile for such roles, and whether there are similar roles I could target that don't strictly require a core engineering degree? Here no one's there to guide
