This report presents a high-level assessment of CO₂ storage resources within the Leduc and Cooking Lake formations of central Alberta. It constitutes Stage 1A and 1B of a multi-phase Resource Assessment program. Key Topics Covered:

  • Resource Assessment Framework - Based on the SRMS (Storage Resource Management System) classification framework
  • Geologic Setting & Reservoir Quality - Stratigraphy, lithology, and thickness of the Leduc and Cooking Lake formations; Leduc reef buildups along the Homeglen-Rimbey-Meadowbrook Trend Hydrostratigraphy - Dual role of the Cooking Lake Formation as both aquifer and seal; hydraulic head and pressure distribution
  • Carbon Storage Calculations - Pore volume estimates, CO₂ density from isotherm and pressure data, estimated effective storage resource (Esaline)
  • Depleted Pools - Assessment of legacy production areas and their implications
  • Results & Discussion- Storage estimates, pore space conflicts (CCS permits, lithium extraction, monitoring zones), and future Phase II modelling
