HORN RIVER BASIN AQUIFER CHARACTERIZATION PROJECT RESERVOIR QUALITY MAPPING • Quantification of aquifer potential a product of reservoir thickness and quality: porosity‐thickness maps • Mattson and Cretaceous sandstones quantified using standard log porosity cutoffs – Mattson 6% Φ cutoff (generally fine‐grained) – Cretaceous 3% Φ cutoff (coarser‐grained) • “Detrital” carbonates more difficult to quantify – Variable mineralogy, fracturing, and heterogeneity render porosity logs only qualitative indicators of reservoir quality – Classify reservoir as excellent / good / poor based on sample cuttings logs, well logs, and wellsite cuttings logs (approx. 3/6/9% Φ cutoffs) – Calculate Φ‐h as: • Enhanced reservoir thickness (m) x reservoir quality porosity cutoff value
NET POROUS ISOPACH MATTSON FORMATION • 6% Φ cutoff • >100 metres of 6% (+) sst a few km west of HRB shale gas project areas, but none within current developments
