Abstract

Reef complexes situated on carbonate platforms contain a disproportionate amount of hydrocarbon reserves. In Western Canada, approximately half of the oil and gas pools with recoverable reserves greater than 16 X 106 m3 (100 million barrels) of oil or its gas equivalent are Devonian reef complexes. Cores and wireline logs from producing and outlying wells from these pools provide perhaps an unparalleled opportunity to examine the evolution of reef complexes in all three dimensions.

Most of the hydrocarbon bearing Devonian reef complexes in the WCSB are isolate features situated on areally widespread carbonate platforms. They include the Middle Devonian (late Givetian) Swan Hills reef complexes in west-central Alberta and the Kee Scarp buildup at Norman Wells in the Northwest Territories; and the Late Devonian (Frasnian) Leduc reef complexes in both east-central and west-central Alberta. The previous chapter dealt with the evolution of the underlying carbonate platform and its relationship to reef inception and localization. This chapter focuses primarily on the evolution of isolate platform-reef complexes. The Swan Hills buildup at Judy Creek in west-central Alberta is used as an example to illustrate the evolutionary development of these complexes.
