CHINKEH GETHING BLUESKY ISOPACH CRETACEOUS SANDSTONES • Gething valley fill to east • Bluesky shoreface to southeast • Chinkeh fluvial / deltaic to west (Liard Basin)
HORN RIVER BASIN AQUIFER CHARACTERIZATION PROJECT RESERVOIR ROCK SUMMARY • Mississippian carbonate platform – Limited reservoir quality in shoaling‐up cycles in middle to upper Rundle and Debolt – Local dolomitization / solution enhances reservoir quality in upper parts of cycles – Capping “detrital zone” exhibits widespread and generally good to excellent reservoir quality • Mattson Formation – Variable but generally good reservoir quality – Thickens sharply westward from Bovie Fault Zone; absent in HRB • Cretaceous sandstones – Gething valley fill (eastern flank) relatively thin, but has some good reservoir – Bluesky shoreface (southeast) –moderate reservoir quality, only locally developed – Chinkeh Formation (western flank) –moderate reservoir quality, possible local importance in far northwest
