should be above 12K since your experience is below 10 years. Most of the consulting and oil & gas firms in qatar considered senior engineers with above 10years experience and I am pretty sure that they are earning beyond 18K a month. I should now this coz I also work in a consulting firm... but if you'll have an offer in a government oil and gas firm, demand should be more than 20K plus accommodation (as this is terribly costly). offers varies also if you are a bachelor or family man... all the best
