hey guys ,
I recently finished my masters in oil and gas engineering , i want to start going for a phd but in a different field or a related one , but i don't know what majors i can switch to , i also did my BSc in petroleum engineering so i am confused in what major my previous degrees allow me to apply.
I tried speaking to professors , one in earth science and one in mathematics both of them said that i dont have the equivalent degree for these majors, what are my options ?
