Hey Kishan,

There are many good oil & gas companies operating in India and they offer good roles. A lot of companies directly or through consultancies hire Indian for foreign locations. Also, in oil & gas industry one can directly apply to outside India and can expect to be hired if have a good profile. So prospects are not bad. But, as far I have seen it - oil & gas industry doesn't really work the way all other when it comes to picking candidates. Someone, just going to college and finishing with good grades might find it difficult to land a desired job. This industry looks for people with a lot of people and management skill. Proactive people, who network, share ideas and stay active around stand much better chances. So, one needs to keep that in mind.Shell, Cairn, Reliance, OIL, ONGC, Halliburton, Schlumberger, Baker Hughes, Wetherford, Transocean etc. are some name which hire petroleum engineers. Other than that a lot of consultancy mostly Mumbai based hire a lot of field employees and engineers for Middle East locations. 

All the best!
