Geology Newsletter 2025

13 In 2024, I taught seven in-person courses and a popular online course offered both semesters. I regularly teach two CEAT Petroleum Engineering Minor courses: Petroleum Geology for Engineers and Applied Well Log Analysis for Engineers. I also teach Introduction to Well Log Analysis for undergraduates and Advanced Well Log Analysis for graduate students, both focused on integrating core and log data to solve subsurface challenges. In the spring, I taught Climate Change and Humanity, a cross-listed geology/geography course. I continued teaching Geology of the National Parks, offered online and in person—Fall 2024 saw an enrollment shift favoring the in-person section. I also led the Honors add-on course The Power of Water: Sculpting the Earth, examining how geology shapes environments and sustainability.Outside the classroom, I served on two master’s committees: one student defended in December, and another is pursuing a feasibility study on COCUS in the Appalachians. MARY HILEMAN VISITING ASSOCIATE PROFESSOR Sequence Stratigraphy, Petroleum Exploitation, Geoscience Education Adjunct Teaching Faculty in School of Geology since 2009 A number of our professors are working on Managed Aquifer Recharge (MAR) in the Arbuckle Simpson aquifer. Dr. Beckmann (adjunct from microbiology) is working with Dr. Xu on biogeochemical changes. Dr. Halihan is working with Dr. Zhang on measuring and modeling recharge changes and effects. The project is funded by EPA in partnership with ECU in Ada and Texas State University in San Marcos, Texas, as well as tribal and nonprofit partners. We have a number of undergraduate, graduate and post doctoral fellows working to increase recharge to the aquifer that supplies water to a significant number of people in south central Oklahoma.
