A carbon storage session is going to be held at the Goldschmidt conference in Paris. The conference will take place from August 13-18 and the abstract deadline is April 1st (just before midnight CET). The organisers would very much appreciate your input in the conference and of course also in their session, for which all details are provided below!
19f: Techniques and Technologies to Ensure Efficient and Secure Geological Storage of CO2: Insights from Laboratory Tests, (Reactive) Transport Modelling and Field Tests
Confirmed invited speaker: Dr. John P. Kaszuba, Department of Geology & Geophysics, University of Wyoming
The storage of anthropogenic CO2 offers a method to mitigate climate change. While a vast amount of research has addressed this technology, gaps in our understanding of the coupled geochemical, geomechanical and fluid flow associated with CO2-water-rock interactions still exist. A better understanding of these processes is crucial for targeted and efficient monitoring strategies to detect potential leakage associated with the storage complex and its overburden. Core-scale laboratory tests to quantify short-term and long-term reactions, field observations of flow phenomena and characterization of migration pathways for fluids in the sedimentary overburden are required. Observations of coupled reactive-transport, including forward modelling and history matching of these processes, can provide insight into the geochemical reactions controlling reservoir, caprock and fracture alterations. On a reservoir scale, identifying reliable tracers for fluid source identification, quantifying sedimentary fluxes of CO2 and monitoring relevant geochemical species in sediment and water column will advance the de-risking of this technology. This session will explore advances and techniques around safe carbon capture and storage and will bring together the results gained from core- to field scale experimental and modelling work as well as pilot tests and analogue studies. We invite contributions addressing the interaction of CO2 and co-contaminants with wellbore cements and reservoir, fault and seal rocks in order to predict mineral and flow property alterations and explore the impact on monitoring strategies. We would further be interested in integrated studies, improving the knowledge of coupled hydro-geochemical-geomechanical processes.
