Gas hydrate accumulations represent a massive global carbon reservoir with significant implications for energy resources, geohazards, and carbon cycling. While recent drilling and production tests have advanced our understanding of hydrate systems and system dynamics in marine and permafrost settings, discrepancies remain between observed reservoir responses and numerical model predictions. Critical uncertainties persist regarding fluid flow, lithology, permeability, and gas migration. All of these can have important influence on gas hydrate saturation and on system stability under changing physical conditions, including both long-term environmental factors and human-induced depressurization. This session invites contributions that offer insights into hydrate systems and system dynamics in marine, Arctic and permafrost environments through geological, geophysical, geochemical, and production-related data from field, laboratory, or modelling studies. We particularly encourage research utilizing emerging technologies, such as AI/Machine Learning, predictive modelling, and distributed fiber-optic sensing.
