It takes the name from the town of Mannville, Alberta, and was first described in the Northwest Mannville 1 well by A.W. Nauss in 1945.[2]
Lithology
The Mannville Group consists of interbedded continental sand and shale in the base, followed by a calcareous sandstone member, marine shale, glauconitic sandstone and salt and pepper sandstone. An additional non-marine sequence is present in north-eastern Alberta.
Total gas reserves amount to 316799×106m3 in the Lower Mannville and 644774×106m3 in the Upper Mannville.[5] Recoverable oil reserves amount to 105.64×106m3 in the Lower Mannville and 199.20×106m3 in the Upper Mannville.[6]
Distribution
The Mannville Group reaches a thickness of 145 feet (40m) in its type locality. It occurs in the sub-surface in central Alberta, extending east-west from Edmonton to Lloydminster and north-south from the Deep Basin to the United States border. It is present in the sub-surface in west-central and southern Saskatchewan.
