... Abstract Understanding CO 2 /brine relative permeability is crucial for modeling fluid flow in CO 2 storage projects, which directly impacts the assessment of storage capacity, maximum injection rates, plume migration, and area of review (AoR). The U.S. Environmental Protection Agency (EPA...

... Abstract During CO 2 -saturated brine injection in deep saline aquifers, there is a potential occurrence of formation damage or permeability enhancement. This can be due to the reactive interaction between the injected CO 2 -saturated brine and the formation rock. Therefore, in this study, we...

... coupled geomechanics-hydrodynamic simulation was performed incorporating the Kozeny-Carman stress-dependent permeability correlation to understand the changes in permeability and effective stress dynamics with the increase in reservoir pressure due to the CO 2 injection. The capillary entry pressure...

... to evaluate their ability to predict the distribution of injection fluids. Wireline logging and electromagnetic survey are employed to construct reservoir model, which are then coupled with a geo-mechanical framework that links fracture permeability to pore pressure. The injection test covered a wide range...

... Abstract The study describes the complex process of dissolution, precipitation and mineralogical alteration caused by saline carbonated water injection (CWI) and its effects on the petrophysical properties (porosity and permeability) of limestone samples from the Mupe Member, composed...

In this study, we generated geo-barriers in a core-scale experimental setup. We used a special core flooding setup which...

... containing incompatible ions, in this case, Ba 2 ⁺ and SO 4 2 ⁻ , which react to form barite (BaSO 4 ). The resulting barite precipitation will reduce the pore space where the two brines meet along the boundary and decrease the permeability. Eventually, this will effectively act as a barrier which can...
