The interaction of fluid and rock, and the properties of pores and their connectivity are among the main controls on the production and storage potential in clastic and carbonate rocks. At least as much as in the hydrocarbon sector, the exploration of geothermal resources or storage sites for CO2 or hydrogen, require knowledge of processes on the pore scale. Compaction, cementation, dissolution, and alteration, control the evolution of reservoir quality and are also key to understanding the risk of formation damage. All may occur on geological time scales or happen rather quickly during production or storage as the composition and/or pressure of the pore fluids is changed dramatically within a short period of time. The process-based understanding of diagenesis controlling reservoir behavior will aid in future utilization of the subsurface in outlining possibilities for better assessment, prediction chances and risks of classic and renewable energy. Numerical simulations are the only way to connect micro-scale processes, which may significantly alter the internal rock structure, with the macro-scale, which consequently affect the hydraulic behaviour of the system.
This session aims to showcase recent developments in reservoir petrography, petrographic modelling, and prediction utilizing multiple geological, geochemical, and geophysical methods and approaches like reactive transport modelling. We invite submissions presenting e.g., case studies, integrations of novel methodologies, and new interpretations of legacy data for future energy challenges.
