“Computed Tomography for HPHT THMC Studies of Materials in a Triaxial Setting” The talk introduces an experimental platform originally designed at Stanford University. The system is an X-ray compatible, high temperature (>400 °C), high pressure (>2000 psi confining, >140 kN axial load) core holder for a medical CT scanner, allowing for the in-situ study of reactive flow mechanisms under effective stress conditions. We will discuss various applications, such as employing a non-wetting technique to visualize and quantify sub-core scale porosity evolution associated with kerogen pyrolysis or elucidating poroelasticity/plasticity effects under triaxial loading conditions. The platform serves as a basis for a 2^nd generation system targeting axial loads of more than 1000 kN and confining pressures of 10,000 psi while maintaining the original temperature rating. Targeted applications range from in situ studies for enhanced geothermal systems, carbon mineralization, and geologic hydrogen to stress testing of engineered materials. In addition, we will briefly touch on plans for establishing a Thermal-Hydrological-Mechanical-Chemical (THMC) Lab at the University of Kansas.
