Overview

Analytical model for evaluating leakage in faulted reservoirs, indicating implications for CO2 and H2 storage.

Key Points

  • Leakage detection indicates potential issues in underground CO2 and H2 storage, emphasizing the importance of reservoir monitoring.
  • A transient pressure drop analysis revealed that pressure variations correlate with fault permeability and reservoir conditions.
  • The methodology utilizes Laplace and Fourier transforms to derive solutions for hydraulic diffusivity equations.
  • These findings may enable better safety measures in geological storage systems, reducing risks during energy transitions.
