No one can truly predict the future. The BLS clearly just thinks that, in the estimation, petroleum jobs are expected to increase over the next 10 years. Of course that 10 year outlook is from 2014 to 2024, so it’s entirely possible that the projected growth is based on 2014 data, which is obviously before the bottom fell out of the petroleum market.
Of course regardless of this fact, the (developed) world is still set to (slowly) move away from hydrocarbons. How fast that will actually happen is anyone’s guess. It might be 10 years or it might be 50 years. No one really knows.
