SUMMARY:CSSR Open Webinar Series 2026
DESCRIPTION:CSSR webinar #3/2026 \nPlease register here for the webinar: https://events.teams.microsoft.com/event/8db63eea-a1e7-4a29-b13b-9186756dc193@70a6eba4-9671-45d2-b83e-432e06502242 \nDear colleagues\, \nWe are pleased to invite you to the upcoming webinar in the CSSR Open Webinar Series for 2026. \nTitle: From Pores to Cores: How Flow Interruptions Shape Particle Deposition \nSpeaker: Tongtong Yu is a PhD student in WP1–Reservoir Physics with a background in petroleum engineering. Her current research at NORCE focuses on experimental studies of particle transport in porous media at both core scale and pore scale.\nDate & Time:  10 April 2026\, 09:00-10:00 CET \n🔹 About CSSR\nThe Centre for Sustainable Subsurface Resources (CSSR) is a national research centre funded by the Research Council of Norway and a consortium of industry sponsors. CSSR is dedicated to advancing research and innovation in low-emission subsurface applications\, with a strong focus on reservoir management\, CO₂ storage\, and the sustainable use of Norway’s subsurface resources. Our goal is to support the transition to a low-emission society through science-based solutions and collaborative research. Learn more at www.cssr.no. \n🔹 Webinar Details\nProduced water reinjection is a key strategy for reservoir pressure maintenance and wastewater management\, yet suspended particles can induce severe formation damage and injectivity loss. This study integrates pore-scale visualization using glass microfluidic chips and dynamic core flooding experiments in Bentheimer sandstone to elucidate particle transport\, retention\, and clogging under varying flow conditions. Results reveal that injection rate strongly controls deposition patterns: low rates promote external filter cake formation\, intermediate rates lead to deep internal clogging\, and high rates enable partial particle passage. Under cyclic injection\, increasing frequency enhances external cake compression and stability\, reducing overall permeability to below 10 mD. Particle retention strongly depends on pore geometry\, flow heterogeneity\, and particle size. The combined insights emphasize the non-monotonic relationship between injection dynamics and formation damage\, guiding the optimization of produced water reinjection strategies for sustainable reservoir management. \nWho Should Attend: This talk will be of particular interest to: \n\nResearchers and students in geoscience\, reservoir engineering\, and energy systems\nIndustry professionals working in CO₂ storage\, hydrogen storage\, and petroleum reservoir management\nPolicymakers and stakeholders involved in the energy transition and climate strategy\nAnyone interested in data-driven approaches to sustainable subsurface resource use\n\nEvent Format: The session will begin with a short introduction to CSSR and its research focus\, followed by the scientific presentation and an open Q&A session. \nPlease note: The introduction and scientific talk will be recorded and made available after the event. The Q&A session will not be recorded to encourage open discussion. \nWe look forward to welcoming you to this exciting event and to insightful discussions.

DESCRIPTION:Registration link : https://events.teams.microsoft.com/event/23ac76c1-b90a-4e6b-b0d7-3541e77ca8b9@70a6eba4-9671-45d2-b83e-432e06502242 \nAuthor: Dr. Na Liu is a Research Scientist at the University of Bergen specializing in pore-scale processes in porous geological media. Her research integrates microfluidic experiments\, imaging\, and geochemical analysis to investigate multiphase flow\, mineral–fluid interactions\, and microbial processes affecting subsurface hydrogen behaviour. Within the Centre for Sustainable Subsurface Resources\, she serves as Deputy Leader of Work Package 2\, contributing to research on coupled transport and reactive processes in subsurface energy systems. \nTitle: Microfluidic Platforms for Pore-Scale Investigation of Sulfate-Reducing Bacteria under Hydrogen Storage Conditions \nAbstract: Microfluidic platforms are increasingly used to investigate microbial processes at pore-scale because they provide optical accessibility\, experimental control and relatively low cost. However\, different chip materials and designs impose distinct physical and chemical constraints\, which can significantly influence anaerobic microbial experiments relevant to subsurface hydrogen systems. Selecting the appropriate platform is therefore not trivial. \nI will compare three types of micromodels: (i) high-pressure silicon/glass microfluidic chips\, (ii) polymer-based ibidi microchips\, and (iii) natural-rock micromodels fabricated from sandstone. As a representative case\, we use the sulfate-reducing bacterium Oleidesulfovibrio alaskensis G20\, which consumes hydrogen as an electron donor and produces sulfide. \nThe silicon/glass chips enable experiments under elevated pressure and temperature conditions representative of reservoirs\, allowing quantitative assessment of hydrogen consumption\, biofilm growth\, wettability alteration and flow redistribution. Ibidi microchips provide excellent compatibility with confocal microscopy and Raman spectroscopy\, facilitating real-time visualization of microbial activity under controlled anaerobic conditions at atmospheric pressure. Natural-rock micromodels introduce realistic mineralogy and surface heterogeneity\, improving geological relevance\, but present challenges related to sealing\, hydrogen leakage\, and material compatibility. \nBy systematically comparing these platforms\, I aim to clarify their respective strengths and limitations and to discuss how they can be strategically combined in a hierarchical experimental approach. The goal is to support robust pore-scale investigations of bio-geochemical processes relevant to hydrogen storage and subsurface energy systems. \n🔹 About CSSR\nThe Centre for Sustainable Subsurface Resources (CSSR) is a national research centre funded by the Research Council of Norway and a consortium of industry sponsors.
