Implication

Randomized trial explores CO2-brine displacement dynamics in heterogeneous reservoirs, indicating significant implications for CO2 storage efficiency.

Key Points

The study aims to evaluate the effects of velocity-dependent relative permeability on CO2-brine displacement in geological carbon storage.
Utilized a hybrid approach combining numerical modelling in Petrel and an analytical model for CO2-water displacement.
Developed velocity-dependent relative permeability functions to model fluid movement across varying flow regimes.
Conducted sensitivity analysis to assess the impact of reservoir heterogeneity on CO2 redistribution.
Velocity-dependent relative permeability functions improved predictive accuracy of CO2 displacement.
Analysis revealed that heterogeneity significantly influences the vertical redistribution of CO2 in the reservoir.
Findings indicate implications for both solubility and residual trapping efficiency of CO2 during geosequestration.
