Benchmarking CO$_2$ Storage Simulations: Results from the 11th Society of Petroleum Engineers Comparative Solution Project Open
The 11th Society of Petroleum Engineers Comparative Solution Project (shortened SPE11 herein) benchmarked simulation tools for geological carbon dioxide (CO$_2$) storage. A total of 45 groups from leading research institutions and industry…

Measuring carbonate dissolution rates under well-controlled conditions for reactive CO2-water flow in a large lab-scale karst fracture imitate Open
This study explores the carbonate dissolution dynamics in karstic systems by simulating reactive water flow under controlled large lab-scale laboratory conditions. Using a 1 m² Jura limestone tile, the experiments focus on carbonate dissol…

Implementation Pitfalls for Carbonate Mineral Dissolution -- a Technical Note Open
In systems with slow reaction kinetics, such as mineral dissolution processes, chemical equilibrium cannot be assumed and an accurate understanding of reaction rates is essential; discrepancies in parameter reporting can greatly affect sim…

Dynamics of seasonal CO2 concentrations above and below the karst-water table are influenced by density-driven transport: monitoring data from a cave in the Swabian Jura and interpretation with numerical simulation models Open
It is long known that dissolved aqueous CO2 is the key driving force of chemical reactions leading to rock corrosion, which is denoted as karstification. Accordingly, it is evident that meteoric water percolating through the biologically a…

Seasonal Dynamics of Gaseous CO2 Concentrations in a Karst Cave Correspond with Aqueous Concentrations in a Stagnant Water Column Open
Dissolved CO2 in karst water is the key driving force of karstification. Replenishment of CO2 concentrations in karst water occurs by meteoric water that percolates through the vadose zone, where CO2 produced from microbial activity is dis…
