Origin and Diagenesis of Middle Devonian Pinnacle Reefs Encased in Evaporites, “A” and “E” Pools, Rainbow Field, Alberta
The Rainbow area of petroleum production in Western Canada is located some 400 miles (640 km) northwest of Edmonton, Alberta (Fig. 8-1). The main production is found in Middle Devonian limestone and dolostone reefs, which are encased in evaporites (Figs. 8-2-8-4). The reefs form the Rainbow Member of the Upper Keg River Formation in the Upper Elk Point Subgroup, which is of Givetian Age (Langton and Chin, 1968).
