Re: ONGC GT Petroleum engineering question paper

Hi,

I have appear in GT for Petroleum branch in 2014 and I can remember easily that these are not the question which has been asked.Might be they are belong some other stream.
Question has been asked from reservoir and production facility with some question from shale and cbm. Just focus on basic.

Regards

Vikash
