water injection is an enhanced oil recovery method which is applied for number of reservoirs especially in the offshore fields around the world. sea-water injection process is usually associated with important concerns affecting the efficiency, safety, and economy of the operation like formation damage, mineral scaling, early breakthrough and corrosion. incompatibility between injected and form...

We consider transport of a solute that undergoes a nonlinear heterogeneous reaction: after reaching a threshold concentration value, it precipitates on the solid matrix to form a crystalline solid. The relative importance of three key pore-scale transport mechanisms (advection, molecular diffusion, and reaction) is quantified by the Péclet (Pe) and Damköhler (Da) numbers. We use multiple-scale ...

Our paper ‘‘Upscaling geochemical reaction rates using pore-scale network modeling’’ [1] presents a novel application of pore-scale network modeling to upscale mineral dissolution and precipitation reaction rates from the pore scale to the continuum scale, and demonstrates the methodology by analyzing the scaling behavior of anorthite and kaolinite reaction kinetics under conditions related to ...

Accurate predictions of rock permeability is critical for resource exploration and environmental management. To improve on existing approaches to prediction, this study employed a stochastic pore-scale simulation approach. The petrophysical properties needed the implementation approach are porosity pore size distribution (PSD) samples which can be obtained easily from mercury injection capillar...
