摘要
The late Cretaceous Cardium Formation, which existing in the mud shale Colorado Group has the highest hydrocarbon volumes in the Western Canada Sedimentary Basin （WCSB） of Alberta. It represents approximately 20 percent of the hydrocarbons indentified in WCSB as initial volume-in-place and as remaining established reserves.
