HORN RIVER BASIN AQUIFER CHARACTERIZATION PROJECT CONCLUSIONS (2) • Mississippian carbonates and Cretaceous sands occur within a single hydrostratigraphic unit – Mattson sands geographically separated, on a different water gradient • Waters are saline, but suitable for use as completion fluid – Low concentrations of sour gas seen in Mississippian waters –requires further assessment • Extremely high permeabilities occur in Mississippian “detrital” unit – Flow/injectivity tests, DST’s, cuttings samples, well logs – Mappable along Φ‐h fairways • Relatively limited reservoir potential in sandstone aquifers – Potential local “sweet spots” in Mattson and Chinkeh
