Guides to the Geology of
These information sheets are provided as companions to the contour maps. Included on each sheet is a brief geological description of productive geological horizons for that portion of the province, reservoir characteristics and production information, bibliography and relevant publications, reference wells, type logs, schematics, and cross-sections. The areas and horizons covered are: Upper Cretaceous of Western Saskatchewan; Lower Cretaceous of NW Saskatchewan; Lower Cretaceous Mannville Group, Jurassic, and Mississippian of SW Saskatchewan; Wapella Area SE Saskatchewan; Mississippian SE Saskatchewan; Middle Bakken Sand West-Central Saskatchewan; and Devonian SE Saskatchewan.
The guide sheets are available in PDF format and may be viewed in Adobe Acrobat Reader or, if you require a hard copy, they are best printed on a plotter at paper size 36” x 48”
Map Lists (PDF Format)
It is recommended that you reference the Map Lists first to create a frame of reference before consulting the Index Maps. There are two Map Lists - one sorts the maps by geological horizon while the second sorts the maps by Map #. On these lists, those maps with partial coverage are noted and flagged. The Map Lists themselves include a provincial grid followed by a listing of maps available for each map of the grid.
The 'Code' identifies the map by type, map #, and horizon. The map types are SC (structure contour map), SUB (subcrop map), and ISO (isopach map). For example, SC 1 – Mes is read as 'structure contour map of the Mississippian Erosion Surface in map grid #1'. The 'Well Data Current to:' column indicates the off-confidential date that was used to generate the map. For example, 01-Jan-03 tells us that the well data used was based on an off-confidential date of January 1, 2003. The Map Lists will be updated as revisions, expansions, and new horizons are added.

Index Maps (PDF Format)
The Index Maps are used to determine the extent of coverage for a particular horizon. The geological horizons that are mapped include the Ribstone Creek Member (Belly River Formation), Milk River Formation, Medicine Hat Sandstone, Second White Speckled Shale, Lower Colorado Group, Viking Sand, Mannville Group, Index Horizon Above the Cantuar Marker (IHACM), Wapella Sand, Jurassic Erosion Surface, Base of the Jurassic Shale Marker, Base of the Roseray Sand, Lower Shaunavon Formation, Lower Watrous Formation, Mississippian Erosion Surface, Madison Group, Ratcliffe Beds, Base of the Oungre Evaporite, Midale Beds, Middle Bakken Sand, Birdbear Formation, and the Winnipegosis Formation.
The PDF maps can be viewed in Adobe Acrobat Reader or, if you require a hard copy, they are designed to be printed on a plotter at paper size 36” x 48” at a scale of 1” to 1 mile. However, if paper size restrictions are an issue, you can zoom in on the PDF map and print off that portion on a smaller paper size.
