Switching from a Molecular Biology major to Geosciences with an emphasis on Geophysics is considered a viable option for pursuing a career in Petroleum Engineering, especially since the University of Texas at Dallas does not offer a Petroleum Engineering degree. However, there are concerns about potential disadvantages compared to students with a B.S. in Petroleum Engineering, particularly regarding eligibility for the Professional Engineer (PE) exam. Some participants suggest that a background in mechanical or civil engineering may be more beneficial for an undergraduate degree before pursuing a master's in Petroleum Engineering. The discussion highlights the importance of aligning educational choices with career goals, noting that both geophysics and engineering paths can lead to success in the field, depending on individual interests. Additionally, taking introductory geology courses is recommended to assess interest in geosciences. There is also a query about combining a major in computer hardware engineering with a minor in geology or geophysics, which could provide qualifications relevant to oil and gas extraction.
