Masters in Petroleum/Reservoir Engineering - Is it worth it ?

To add some context, I've recently graduated with a BSc in Chemistry, Management and Analytical Chemistry and have been working the past few months in a pesticides inspectorate. However I've always been interested in Engineering and there is an opportunity for me to do my Masters as indicated in the title of this post. I'm a bit confused as a person (just turned 23) and would appreciate some input from engineers in the field.

How likely is it for companies to hire me post Masters given by first degree is not in engineering?

If I do a Masters full time then I won't get any job experience. How difficult would that make it to then get a job? Even if I do a Masters part time and decide to work, would Oil and Gas companies hire students like me?

Is doing a PEng Masters even worth it given my situation? Where would the industry be in the next 30 to 40 years? (Many people I've asked gave completely different views on this).

Thanks for any feedback.
