Coupling tough2 and SEAWAT variable-density models to understand potential geologic carbon sequestration impacts on groundwater resources
… developed for a calibrated MODFLOW model. The migration of native brine and its impact on freshwater drinking sources is investigated by passing pressure and salt concentration data between the models at specific time steps. Results show the method to be successful with pressure impacts of the …

Re-evaluation of Kombat-style mineralisation and implications for exploration in the Otavi mountainland, Namibia
… as determined by fluid inclusion studies. Upward brine migration enabled leaching of metals from underlying sediments and precipitation of Cu-Pb ore at upper levels in the carbonate host rocks due to structural traps and chemical interaction. The syn-sedimentary Fe-Mn ore, which is largely …

Paleohydrogeology of the Alberta Basin, Canada
… and hydrogeologic studies. In this study, brine migration and groundwater age were simulated over the last 100 million years, along a 700 Km, east-west cross-section of the basin, using salinity and Cl/Br ratios as geochemical constraints. The 2D finite element FORTRAN code COMPACT was used …

A study of the berg Aukas-type Pb-Zn-V deposits in the Otavi mountain land, Namibia
… diagenetic stages. The influence of basinal brines enriched in radiogenic strontium as a consequence of the reaction with Rb-bearing phases, especially detrital (clay) minerals hosted by underlying basement rocks, is considered to be most likely. Stable isotope investigations carried out on …

Microscopic study of salt precipitation dynamics during the injection process of CO2 storage in saline aquifers
… by injection flow rate, pore structure, and brine properties, is crucial for optimizing CCUS strategies. This thesis examines the impact of salt precipitation on CO₂ geological storage in saline aquifers using microfluidic experiments and molecular dynamics simulations. It analyses the …
