Utilisation of the geosphere and environmental protection are in the focus of the Centre for CO2 Storage. This interdisciplinary group studies geotechnical applications with a holistic approach.

CO2 Storage
The CO₂MAN (CO₂ Reservoir Management) integrated project aims to advance the understanding of the science and practical processes involved in underground storage of CO₂ to reduce emissions of greenhouse gases to the atmosphere. The consortium running this BMBF/GEOTECHNOLOGIEN project consists of 6 partners.

Geophysical Monitoring

The centre for CO₂ storage applies and develops seismic and geoelectrical techniques to monitor the CO₂ storage formation. We combine borehole and surface based methods in order to achieve high resolution close to the injection as well as a high degree of spatial coverage for monitoring the reservoir as a whole. The methods applied comprise 2D and 3D seismics, (offset) VSP, seismic crosshole tomography, geoelectrical crosshole tomography and surface-downhole geoelectrics. Within collaborations with internal and external partners further seismological and electromagnetic monitoring methods are being investigated.

Process Modelling

The Process Modelling Group of the Centre for CO₂ Storage investigatescoupled processes occurring in CO₂ storage formations usingnumerical modelling. Our goals are the support of storage operations and theprediction of long-term behavior of the injected CO₂. The Ketzin pilot site plays an important role within the scope of our main activities.

Fluidexperimente und Petrophysik

Die Injektion von CO₂ stört das chemische Gleichgewicht im Speichersystem und induziert Wechselwirkungen zwischen injiziertem CO₂, salzhaltigem Formationsfluid sowie Reservoir- und Deckgestein. Diese Wechselwirkungen verändern die chemischen, physikalischen und mineralogischen Eigenschaften des Speichersystems. Ziel der Abteilung Fluidexperimente und Petrophysik im Zentrum für CO₂-Speicherung ist es, diese Wechselwirkungen bzw. die Änderungen der chemischen, physikalischen und mineralogischen Eigenschaften des Speichersystems unter kontrollierten Bedingungen im Labormaßstab qualitativ und quantitativ zu untersuchen.
