Undergraduate education in petroleum engineering (PE) has survived the latest downturn in the industry, and enrollment has started to show an uptick in numbers. However, a different trend is evident in graduate training and academic research: the number of researchers being trained in oil and gas topics is drastically dropping. The story can be summarized in Fig. 1. Funding trends in PE departments have been shifting away from oil and gas research. These shifts require large investments in skill-building, expertise, and laboratory infrastructure, which makes it much harder to reverse the trend. Consequently, the shift may permanently alter the identity of PE departments, something that will not impact only graduate education but could alter the overall identity of these departments and the workforce they train. The data shared in Fig. 1c shows that more than 50% of the 2023 research awards, which will fund graduate students earning degrees between 2025 and 2026, are going to be invested in geothermal, carbon management, hydrogen, emissions, and other topics that do not support improving oil and gas resource extraction. While 73% of the 2023 MSc and PhD graduates still studied oil and gas topics around reservoir, production, fracturing, and drilling, as shown in Fig. 1a, this number is expected to drop to under 50% for 2026 graduates. Fig. 1b reveals the accelerated trend of this transition, where only 65% of the publications generated from these departments in 2023 covered oil and gas topics. Under 60% of the 2024 and 2025 graduates who published in 2023 are building expertise in oil and gas research and development. The team collected data to study the trends over the past 10 years. It included over $137 million in external research funding and over 1,900 thesis/dissertations, in addition to over 1,100 publications in 2023. More details about these numbers can be found in SPE 220735. The trends in graduate training and research funding over the past 10 years are shown in Fig. 2, where the axis for graduate training is shifted by 3 years to account for the lag between the date funding was received and the graduation date for the students it supported. When looking at numbers rather than percentages (Fig. 3), oil and gas research funding to four of the major PE departments in the US dropped from $30 million in 2014 to under $10 million in 2023 as shown in Fig. 3a. Funding in these departments now hovers at around $20 million, where the gap was filled by transitioning to the study of sustainable geoenergy topics relating to carbon and hydrogen storage and the extraction of geothermal energy, as shown in Fig. 3b.
