Oil and Gas industry may bring you the big bucks, but there are many trade-offs.
One of the most obvious, the time spent with your family and friends are definitely lesser.
Having spent 8 months interning in an O&G company, it definitely wasn't all fun and joy there. The stress and workload is high, the working hours are long, and basically, oil and gas companies are situated at remote places, i.e. no fun.

However, if you really want to venture into this field for the sake of money, go for servicing companies such as Halliburton, Schlumberger, Baker Hughes etc.
Operating companies such as Petronas and Shell does not have that high pay compared to servicing companies.

For example: basic pay for fresh grad in Halliburton RM4.5k+, in schlumberger RM5k+
In petronas, it is only RM 4k, Shell RM 3.8k

But you have to set your priorities right.
When I interned there, my collegues always tell me, yes the pay is good, but you get shit all the time, no life.

Just my 2 cents.

Cmon, dont be sarcastic. It's just what my collegues are going through and just wanna share with all of you. Sharing is caring. Different people are entitled to different opinion and I'm sure everyone is free to share their opinion here as well.
