If you’re willing to take those risks, expect to study plenty of math and science. At the University of Texas, a top school for this field, some courses for the petroleum engineering degree include: engineering, energy and the environment in the first year; mechanics of solids in the second year; petrophysics in the third year; and reservoir geomechanics in the final year.
As a student, you have many options available to fund your education.

Majors are not static - they will change and evolve over time.  Things constantly change as knowledge, practices, technologies, industries, etc. continue to evolve and mankind continues to push the envelope. So, understanding that selecting a college major is not about picking one area of concentration for the rest of your life. It is more about picking an area of study - demonstrating your aptitude, perseverance, focus and ability to master subjects – which will be attractive to future employers or opportunities where your credential will be one of the characteristics that helps you stand out from the crowd.
Chemical engineers harness chemical reactions to produce things people want. It's a very broad field that overlaps considerably with other branches of engineering , chemistry , and biochemistry . Chemical engineering majors learn how to reorganize the structure of molecules and how to design chemical processes through which chemicals, petroleum, foods, and pharmaceuticals can undergo. You'll learn how to build and operate industrial plants where raw materials are chemically altered. You'll learn how to keep the environment safe from potential pollution and hazardous waste, too. Paper mills, manufacturers of fertilizers, pharmaceutical companies, plastics makers, and tons of other kinds of firms will be looking for your expertise.
I was/am a nontraditional student (about five to seven years older than most students at my university), so this was not quite in my realm, but I was often jealous of the many opportunities afforded to these students.
