If you can get into front office servicing oil/gas industry as
- corporate banker who arrange trade financing, structure loans, cash management
- m&a banker who do ipo, debt capital financing, arrange off-take, syndicate loans
- corp finance advisory who arranges structured financing, commodities hedging solutions
- energy trading - physical or derivatives
- equity research of oil gas industries
- buy side pte equity

it worth a try - mid 30s banker earn 400k in total comp on average, with exception of corp banker who should hit 200k - still better than hard core engineering

Other that that, dont bother
