Overview

Randomized trial demonstrates the effects of heterogeneity on CO2-brine displacement, suggesting new mathematical model implications.

Key Points

  • This work aims to develop a hybrid analytical-numerical model to analyze CO2-brine displacement influenced by heterogeneity.
  • Utilized a hybrid approach combining numerical modeling in Petrel and a novel analytical model.
  • Introduced velocity-dependent relative permeability functions.
  • Performed sensitivity analysis on CO2 vertical redistribution in heterogeneous reservoirs.
  • Heterogeneity significantly influences vertical CO2 redistribution in the reservoir.
  • New analytical framework improved predictions of sweep efficiency and injectivity.
  • Velocity-dependent relative permeability functions enhance accuracy compared to standard models.
