Permeability is a fundamental physical property. A thorough understanding of permeability, and the evolution of permeability with time/strain/stress, is important in many facets of geoscience (e.g., volcanology, structural geology, geothermal energy, geotechnical engineering, and petroleum geoscience). For example, the permeability of volcanic rocks, and and the connectivity and mobility of bubbles in conduit magma, could exert a first order control on the efficiency of the outgassing of the conduit and therefore dictate eruption style and intensity. Understanding the permeability, and permeability anisotropy, of fault zone structures is paramount for predicting crustal fluid flow. Permeability is also of great importance for industrial applications, such as geothermal energy. A thorough understanding of the permeability of highly altered and fractured reservoir rock, and how it evolves over time, is a key aspect for the optimal utilisation of geothermal resources. For these reasons, considerable effort across the field of geoscience is focussed on understanding and quantifying permeability through combined field, laboratory, and modelling studies. Indeed, the number of working groups, and the pace of our understanding, has increased dramatically in recent years. This session hopes to stimulate interaction between the many groups working on this topic (academic and industrial): teams working in the field, those measuring permeability in the laboratory, and the groups that utilise sophisticated modelling. We particularly welcome abstracts from young scientists.
