A coupled geochemical-transport-geomechanical model to address caprock integrity during long-term CO2 storage

Underground storage of CO2 will lead to chemical fluid-rock interactions which may potentially alter the porosity and the flow patterns in faults. In this study, we present a coupled numerical model combining chemical fluid-rock interactions, aqueous diffusion, fluid flow, and mechanical processes, aiming at a better understanding of mineral...

Slicing sodium from bakery products

The need for sodium reduction in our diet is clear to consumers, dieticians and food manufacturers. As sodium concentration has a strengthening effect on gluten, sodium reduction decreases dough mixing tolerance, dough resistance and induces dough stickiness. In particular, the latter may cause problems in mechanical processing of dough. In...

The mechanical impact of CO2 injection

The mechanical impact of CO2 injection into a depleted hydrocarbon field or aquifer is caused by changes in the stress field, resulting from changes in the pore pressure and volume of the rock. Mechanical processes can lead to the loss of reservoir and caprock integrity, and the reactivation of existing faults. A geomechanical numerical...
