Chemical engineer roles in Oil and Gas

I have an offer from manchester to study chemical engineering. Could this degree be useful in obtaining a well paying job in Oil and gas(preferably upstream).

Could i compete with Petroleum engineers for job roles such as reservoir or drilling engineer roles?

I am waiting for my reply from surrey for chemical and petroleum engineering. Would this degree be better for oil and gas?

Also could either of these degrees qualify me for a career in finance such as investment banking if engineering doesnt work out?

Furthermore, i have read that i would have to move to aberdeen for good oil and gas jobs. is this true? tbh i wouldnt mind because i lived in edinburgh for a few months before and loved life in Scotland(yes even the weather).
