"Using mechanical experimentation to explore reservoir response, and bringing the Oklahoma Geological Survey into a blue-green economy"

Abstract – Oklahoma is one of the great energy states of the lower 48, and therefore has enormous subsurface pore space that can be used in the future storage of a wide variety of fuel types and waste products, including carbon dioxide. However, the way this will be implemented in Oklahoma is likely to require novel uses of previously exploited reservoirs for both fossil fuels and induced water. One lesson learned from the unconventional production boom, as well as academic investigations of crustal deformation, was that rocks have a wide variety of mechanical responses at a variety of temporal and spatial scales. Two areas that my research has touched on include microfracture propagation into organic materials in shale, and more generally how granular and plastic (fracture) deformation propagates at different scales. Some of these advances have been applied in near-wellbore environments in carbon-capture experimental sites. Future work will consider how the lessons learned from these geological and experimental studies can be employed in both investigative and engineering research into subsurface use-and-storage targets.


Bio – Dr. Nicholas W. Hayman became the Director of OGS in July 2020. He has a background in science management courtesy of his time at the National Science Foundation as a Program Director for the Marine Geology and Geophysics Program of the Ocean Sciences Division (2018-2020). During that time, and since 2007, Dr. Hayman was a Research Associate (and then Research Scientist) at the University of Texas, Austin, Institute for Geophysics 2007-2020. There he participated and led many research projects, and supervised numerous students and postdocs, with support from the National Science Foundation, US Department of Energy, and energy industry sponsors. Prior to UT, Dr. Hayman was a Postdoctoral Research Scientist at Duke University, Earth and Ocean Sciences 2003-2007. His primary research focus has been the many ways that deformation impacts the crust and upper mantle of the earth, from scales as small as nano-pores, to as large as active plate boundaries.

His focus with the OGS is currently to harness the abundant subsurface data in Oklahoma, as well as the eager drive of the people of Oklahoma, to work towards major innovations in society’s access to energy in a resilient and sustainable natural environment.
