The natural gas reservoir of the Pine Creek Field lies exclusively within the Normandville Member of the Stettler Formation, in the Famennian Wabamun Group. Diagenesis of the Normandville Member is marked by the formation of calcite cements, selective and pervasive replacement dolomite, dolomite cements, replacement anhydrite, and sulphide minerals. The Normandville Member carbonates are depleted in delta18O (range = -6.25 to -11.31‰ for calcite and -3.13 to -11.65‰ for dolomite). delta13C values are slightly within the postulated range of values for Devonian marine carbonates, except for late calcite cements that have low delta13C values (range = 1.54 to -26.33‰), due to incorporation of carbon-12 from sulphate-hydrocarbon redox reactions. Fluid inclusion data shows that these diagenetic mineral phases formed at a temperature range of 76.2 to 154°C. Salinity values for primary fluid inclusion range from 4.2 to 28.9wt% NaCl, showing that the parent fluids of the diagenetic minerals are evaporitic brines.
