CouFrac 2026

5th International Conference on Coupled Processes in Fractured Geological Media: Observation, Modeling, and Application.

Welcome to Uppsala 2026
Coupled thermal-hydro-mechanical-chemical (THMC) processes in fractured geological media are fundamental to understanding the Earth’s evolution and essential to a wide range of near-surface and subsurface applications. These include, but are not limited to, carbon sequestration, geothermal energy, nuclear waste disposal, underground energy storage, hydrocarbon recovery, civil infrastructure development, groundwater management, and deep mining of critical minerals. To advance both scientific understanding and engineering practice, it is vital to integrate insights from numerical modelling, laboratory experiments, field observations, and increasingly, data-driven approaches such as machine learning. The interplay of THMC processes across scales continues to be a vibrant and growing area of interdisciplinary research, with broad implications for environmental stewardship, resource management, and hazard mitigation.

The 5th International Conference on Coupled Processes in Fractured Geological Media: Observation, Modeling, and Application (CouFrac2026) will be held in Uppsala, Sweden, on 20-23 September 2026. Following successful editions in Wuhan (2018), Seoul (2020), Berkeley (2022), and Kyoto (2024), CouFrac2026 will provide a dynamic platform for researchers, engineers, and practitioners to share recent advances, exchange ideas, and foster collaborations, in all areas of coupled processes associated with fractured geological media. The conference will cover a wide spectrum of topics, including fundamental process understanding, computational methods, in-situ testing, laboratory studies, and practical applications across geological environments ranging from the near-surface to the deep subsurface. The conference will be held in a face-to-face format only. We look forward to your participation!
