Fluid Flow and Reaction in Reservoir Rock

Introduction to rock properties governing fluid flow: porosity, permeability, permeability tensor, capillary pressure,relative permeability, Darcy’s law for single- and two-phase systems, drainage and imbibition, saturation functions,pressure build-up.Groundwater flow: Vadose and phreatic zones, groundwater table, aquifer-aquitard, fluid potential, groundwater flowdirection, hydrostatic equilibrium, conductivity-storativity-transmissivity, impact of heterogeneity and anisotropy,Darcy’s law for groundwater systems, transient groundwater equation, tracer tests, diffusion and dispersion, 2 phasegroundwater contamination.
Groundwater geochemistry: Major and minor groundwater species, TDS-conductivity-alkalinity-redox potential,activity and fugacity, activity variation with concentration, phase solubility, delta-delta plots, Stiff and Piper plots,reactive contaminants, contaminant retardation, acidic contaminants and reaction with rocks, contaminationremediation.

Geological CO2 storage: CO2 density variation with depth, gas migration under different force balances, viscous-capillary-gravity equilibrium, structural-capillary-solubility-mineral trapping, lithological heterogeneity, Leverett-Jscaling, snap-off and capillary heterogeneity mechanisms, impact of salinity on solubility, mineral dissolution andprecipitation, impact of flow rate on reaction kinetics.
