... ABSTRACT: Clays, mudstones and shales above CO 2 storage reservoirs are all together defining the top seal. In this paper, we evaluate the constrained modulus (M) and permeability (k) of clay sediments, mudstones and shales from the Horda Platform area, offshore Norway, where the CO 2...

..., geochemical reaction, and microbial activity (Heinemann et al., 2021). The density of hydrogen is significantly lower than that of carbon dioxide (CO 2 ) (e.g., ρ H2 = 6.89 kg/m 3 and ρ CO2 = 289.95 kg/m 3 at 10 MPa; Linstrom and Mallard, 2024), leading to a buoyancy force approximately three times...

... ABSTRACT: This paper presents a hydromechanical simulation of large-scale analysis to assess the risk of CO 2 leakage through faults within the reservoir and caprock as potential pathways. The study involves the evaluation of slip tendency and distance to failure of existing faults in both...

... ABSTRACT: Wellbore integrity is critical to the long-term security of CO 2 geological storage. During CO 2 injection, the significant temperature difference between the injected CO 2 and formation at depth will stress the near wellbore region, potentially leading to generation of leakage...

... ABSTRACT: In CCS wells, the hydration products in the cement sheath can react with CO 2 and alter the composition of the barrier. Therefore, cement sheath mechanical properties can change spatially and temporally. Designing an appropriate barrier should account for these changes when...

... ABSTRACT: Some of the potential risks associated with CO 2 sequestration include leakage, induced seismicity, groundwater contamination, reservoir integrity, health and safety risks, long-term liability, economic viability, and operational challenges. Ensuring the safe storage of CO 2 over...

... ABSTRACT: Carbon mineralization in mafic and ultramafic rocks has emerged as a highly promising method for permanent CO 2 sequestration. It is hypothesized that stress concentration, caused by the volume expansion and mineral transformation during carbonation, can cause damage and create new...

... ABSTRACT: The Illinois Basin Decatur Project (IBDP) has piloted the process of large-scale injection of CO 2 into a deep saline reservoir. During the project, microseismic clouds were observed from locations that were not identified in any previous geological database. Based on the injection...
