Overview

Transient analysis shows significant pressure drop in reservoirs with variable thickness, suggesting improvements in geohazards detection and CO2/H2 storage efficiency.

Key Points

  • Pressure drop modeling indicates substantial variations in reservoir performance occurring with changes in thickness, particularly near communicating faults.
  • Sensitivity analysis shows that oil viscosity has a crucial impact on the pressure drop, affecting reservoir evaluation outcomes.
  • Developed Python code effectively implements an image-Laplace-Fourier transform approach to enhance formation evaluations and energy transition efforts.
  • This method highlights the potential to improve geological storage solutions near faults, emphasizing the need for advanced modeling techniques in geohazards.
