Dear colleagues,

We are pleased to invite you to the upcoming webinar in the CSSR Open Webinar Series for 2026.

Title: From Pores to Cores: How Flow Interruptions Shape Particle Deposition

Speaker: 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.
Date & Time:  10 April 2026, 09:00-10:00 CET

🔹 About CSSR
The 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.

🔹 Webinar Details
Produced 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.

Who Should Attend: This talk will be of particular interest to:

• Researchers and students in geoscience, reservoir engineering, and energy systems
• Industry professionals working in CO₂ storage, hydrogen storage, and petroleum reservoir management
• Policymakers and stakeholders involved in the energy transition and climate strategy
• Anyone interested in data-driven approaches to sustainable subsurface resource use

Event 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.

Please 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.

We look forward to welcoming you to this exciting event and to insightful discussions.
