NORMAN, OKLA. – A study led by University of Oklahoma researchers has been selected for a 2023 best paper award in the Advanced Formation Evaluation technical program theme from the Unconventional Resources Technology Conference.
The study examined how clay and kerogen, two different components within rocks, respond to nuclear magnetic resonance, or NMR, a technique used to assess the amount of fluids within rocks. Many fluids found within rocks contain hydrogen, and knowing whether and how much hydrogen is available in the subsurface is an important facet of oil and gas exploration. Researchers found that higher NMR frequencies improved data acquisition efficiency.
As a result of this study, a novel workflow combining NMR and crushed rock analysis was developed to provide more accurate measurements of fluid fractions within rocks. The technique can be critical for determining hydrocarbon concentration within the subsurface and guiding decision-making related to oil and gas projects.
“This research is an example of how our program is using the most advanced technology to move science forward,” said Son Dang, a research scientist at OU and first author of the paper.
Chandra Rai, professor and Martin G. Miller Chair in Petroleum Engineering, said the award means visibility and validation of the high-end research conducted at OU’s Integrated Core Characterization Center in the Mewbourne School of Petroleum and Geological Engineering.

Three University of Oklahoma graduate students have been named winners of the 2025 Three Minute Thesis competition, which challenges participants to explain their research in three minutes to a non-specialist audience.
Sarah Sharif, a researcher with the University of Oklahoma, has been awarded funding from the U.S. Department of Defense (DoD) to create innovative light detectors that pick up mid-wave and long-wave infrared signals at higher temperatures than previously considered achievable.
A team from OU and WVU recently earned a five-year, $3.5 million grant from the National Institutes of Health to study how concept cigarillos influence the potential for addiction. The results will be used to inform the FDA’s impending flavor ban on cigar products and could have wider-reaching implications for other tobacco products that come in flavors, such as e-cigarettes and tobacco-free nicotine pouches.
