Considering petroleum engineering

Guys I am interested and passionate about mechanical engineering and I want to get a bachelors degree in it but the problem is I mostly find their average salary low relatively to other engineering degrees and I am afraid of regretting my desicion 5 years later, so I started to look into other majors and one of them that I found myself not hating it nor loving it is petroleum engineering and I also found that it pays well, and especially I am a gcc student , so I was thinking about it , is it worth it to pursue petroleum engineering(to be honest what made me think about it a little is their pay is very well and it gets better)? And does it have a lot of geology?
