CO2 sequestration refers to a process of capturing an excessive amount of carbon dioxide (CO2) from large sources and storing it in deep geological formations. The success of the overall performance of the geological carbon storage (GCS) units depends on various trapping mechanisms such as structural, capillary, solubility, and mineral mechanisms within the geological systems. Structural trapping within deep geological formations is highly influenced by the rock formation, newly-formed and pre-existing fractures, and faults. The magnitude of the pore pressure due to the injection of CO2 not only depends on the hydrological and geo-mechanical properties of rock formation but also on the wellbore orientation, the injection rate, and the injection schedule. In this presentation, the impact of formation thickness, wellbore orientation, injection rate, presence of a fault, and pre-existing fractures within the caprock is computationally investigated at the reservoir scale. This study highlights that in addition to injection rate, wellbore orientation, and the number of faults in the domain play critical roles in caprock integrity.
Dr. Pania Newell is currently an assistant professor in the Department of Mechanical Engineering at the University of Utah. Prior to joining The University of Utah, she was a member of the technical staff at Sandia National Laboratories. She obtained her M.S. and Ph.D. from the University of New Mexico and University Colorado-Boulder, respectively. Her research interest lies at the interface of material sciences and mechanics. In particular, she is interested in multi-scale, multi-physics phenomena in heterogeneous porous materials through developing theoretical, computational, and experimental frameworks combined with data sciences. She is currently serving as deputy-chairs of AGU-groundwater, ASME-Poromechanics and IACM-Female Researcher Chapter.
