Hey,

The oil and gas industry also has its own predictions of how many petroleum engineers it will need in the future. The American Petroleum Institute expects that by 2035, the industry will employ almost double the number of petroleum engineers in the workforce as of 2015. That amounts to about 30,000 new jobs.

Plus, the industry also expects many current petroleum engineers will retire in the next decade. That means that in addition to the baseline job growth, there could be more than 7,000 additional jobs the industry will need to fill.

Petroleum engineering needs a knowledge of many other disciplines such as geophysics, petroleum geology, formation evaluation, drilling, economics, reservoir simulation, reservoir engineering, well engineering, artificial lift systems, etc.

Petroleum engineers can also work in drilling sites. Job opportunities for the professionals of this field also exist in foreign countries like the United States.

Petroleum engineering degree holders can also start their career in teaching field.

Hence you hold to stand a good future if you chose petroleum engineering and work hard towards  it.

Hope this helps.
