Implication

Review synthesizes modeling, mechanisms, and patterns of CO2 dissolution in saline aquifers, suggesting improved storage efficiency.

Key Points

  • This review aims to synthesize advancements in the modeling and mechanisms of CO2 convective dissolution in saline aquifers.
  • Reviewed fundamental concepts, models, and dissolution patterns in CO2-rich plumes.
  • Examined the effects of permeability heterogeneity and chemical reactions on convective dissolution.
  • Discussed upscaling techniques from fine-scale to reservoir-scale simulations.
  • Identified four principal dissolution patterns: pure diffusion, early convection, stable convection, and convection shutdown.
  • Found that permeability heterogeneity enhances convective intensity and reduces onset time for convection.
  • Revealed that capillarity destabilizes the diffusive layer, yielding greater convective mixing in capillary-dominant systems.
