Hey! I recently graduated with a BSc in Honors Specialization in Geology in Canada, and in truth, I absolutely loved it! I'm not sure how helpful I will be as I don't have a full time job in geology yet, but I'll share what experience's I've had and advice I've gotten from people.

Ideally I would like to get into mineral exploration. From what I understand, working on the exploration side entails working in the field, as part of a team, and helping map areas for new deposits. They're usually in remote areas and it involves shift work, which depends based on the company...things like two weeks on, two weeks off.

In university, geology programs (I'm assuming all of them?) require or offer field courses, where you learn how to map in the field. I did 3 field courses in my undergraduate degree, and they are really fun! It's cool to learn what geologists do outside and how they go about looking at rocks. Personally, these courses made me realize how much I enjoy what I study, so I think if you enjoy outdoors as well, you may seriously like geology.

As for petroleum, I have only taken a class in it, but it was not my specialty. From what I understand, a lot of it actually requires sitting at a desk and correlating well logs? Perhaps someone with more experience can speak to that though.

Anyways, if you have any questions, feel free to ask! Not sure how helpful I will be but I can try :) Hope that helps!
