Hello,

Yes, several PSUs recruit petroleum engineers either through GATE score or they conduct their own entrance examination for the recruitment. PSUs like ONGC, HPCL, GAIL recruit petroleum engineers. You must appear for GATE if you are interested in a PSU which accepts GATE score. You need to score the minimum percentage in your Engineering to be eligible.
