I personally don't recommend petroleum engineering as your Bachelor's degree. Always pursue your Bachelor's degree in core sector, so that you can have a strong backup. Moreover, as this sector is cyclic in nature, it does't assure you jobs in odd times. Petroleum engineering very specialised and streamlined course. It is better to choose such courses at Master's level. If you pursue your degree in mechanical, chemical, civil or any other core branch, the basic fundamentals will remain same. As petroleum engineering is applied branch, fundamentals from your Bachelor will be useful. Anyone can enter in Petroleum engineering but vice versa may not be possible. Today 70 % petroleum graduates in India struggling to get the job in Petroleum sector. They end up with no option other than going for MS or working with small companies. Don't go behind fancy packages they show it as the survey. I know good engineers working for peanuts (2500 month salary provided by one of the rig contractors). People may criticize me but this is reality and one has to accept it (I am talking about Indian point of view where energy sector is still emerging). Now, it's up to you.
