Predictive Multiphase Flow Assessments of Fluid-Mineral Interactions During CO2 and H2 Storage

Explore the critical decarbonization pathways of geologic CO2 sequestration and H2 storage and cycling in this 56-minute lecture by Dr. Shaina Kelly, Assistant Professor of Earth and Environmental Engineering at Columbia University. Dive into the combination of experimental and numerical multiphase reactive transport assessments of brine and non-aqueous fluid flows to evaluate the petrophysical implications of fluid-mineral interactions during injection and drainage scenarios. Examine pore-scale, multiphase computational fluid dynamics (CFD) models implemented in various rock geometries to understand the interplay between wettability, capillary trapping, thin films, and dissolution-nucleation-precipitation in porous media. Learn how these models yield key porous media transport petrophysical properties that inform core-scale and reservoir-scale engineering storage and recovery metrics. Discover the use of petrophysical measurements like NMR in conjunction with reactive core flow experiments and models to determine changes in accessible pore space. Gain insights into emerging research linking and calibrating precipitation models with microfluidic geometries and sintered mineral packs, featuring tunable properties such as porosity, permeability, and reactive mineral inclusions.
