Montney Regional Shale Study

This study provides a petrophysical and geologic analysis of key wells in the Montney and Doig Formations. NUTECH provides insight into the connectivity of textural attributes of the wells with NULOOK Shale Analysis and NUVIEW 2D Attribute Mapping.

The Montney Formation is a Lower Triassic age unconventional reservoir located in the Western Canadian Sedimentary Basin of British Columbia and Alberta, Canada. The formation is composed of siltstone, shale, dolomitic siltstone, and fine grained sandstone. The Montney Formation is unconformably overlain by Jurassic or Cretaceous deposits, and unconformably underlain by the Permian or Carboniferous strata. The Montney Formation reaches a maximum thickness of 920 feet (280 meters), and is estimated to have reserves on the order of 449 TCFG, 14.5 BBNGL, and 1.1 BBO. Horizontal drilling and extensive fracturing is necessary to have hydrocarbons flow through the low permeability siltstone. The Doing Formation is a Middle Triassic age unconventional reservoir located in the Western Canadian Sedimentary Basin of British Columbia and Alberta, Canada.

The Doig Formation is composed of argillaceous siltstone and calcareous phosphatic shale. The Doig, which reaches a maximum thickness of 620 feet (190 meters), conformably overlays the Montney Formation, which is directly under the phosphatic nodular beds of the Doig.
