CO2LPIE Project – Combining in-situ, laboratory, and modelling work to investigate periodic CO2 injection into an argillaceous claystone
In most uses of the subsurface, especially while injecting and extracting fluids into or from a high porous reservoir rock, the existence of an overlying caprock with sufficiently low permeability is crucial for the success of the aforementioned exploitations. However, while a multitude of research has been conducted already on reservoir rocks, too little attention has been given to the equally important, sealing caprocks. As of yet, detailed studies on their behaviour on different scales in time and space are rather scarce. The project CO2LPIE (CO2 Long-term Periodic Injection Experiment [Rebscher et al., 2019; Rebscher et al., 2020]) is committed to contribute to fill these knowledge gaps by combining an in-situ field test with CO2 injection on a time span of 15 years to 20 years. The approach is complemented with extensive geomechanical and geochemical tests in the laboratory as well as site-specific thermal, hydrological, mechanical, and chemical (THMC) computational modelling. These comprehensive investigations can significantly enhance the understanding, description, and prediction of the complex coupled processes in a caprock. Presently, the demand for factual issues are gaining more attention, as the interest in carbon capture, and storage (CCS) resurges, not the least because CCS is obtaining wider recognition as one of the necessary tools to mitigate climate change.

| Summary: | In most uses of the subsurface, especially while injecting and extracting fluids into or from a high porous reservoir rock, the existence of an overlying caprock with sufficiently low permeability is crucial for the success of the aforementioned exploitations.
