I last heard that there was 200+ years of oil left, and that is what we know about. I really wouldnt believe the press or even so called experts on the news. Its all a form of marketing and keeping the prices high.
There is also a lot of money being invested in nuclear energy, 6 power stations will be built over the next 20 years. Then there is the wind farms that are being built all the time.
I really wouldnt worry about running out of oil, we will never see it happen neither will our kids or theirs.
