I had a sales manager who had a saying “what interests my boss fascinates me”  that saying is true for sales people and the relationship they have with their customers.  What interests oil & gas producers is getting oil & gas from formations and low cost.  That is why it is very important as a sales person that you are familiar with formations & fields that are related to the Oil & Gas Producer that is your customer or target customer.  Below is a chart that shows the top 50 formations in Alberta and I have provided a summary of the top 10.


Top 50
  • McMurray Formation outcrops along the Athabasca and Clearwater Rivers near Fort McMurray, in the Athabasca Oil Sands of northeastern Alberta, where it averages about 60 metres (200 ft) thick. It thins eastward into Saskatchewan where, in most areas, it is devoid of bitumen. It has been removed by erosion north of the Athabasca Oil Sands area.
  • Cardium Formation is a stratigraphic unit of Late Cretaceous age in the Western Canada Sedimentary Basin. It takes the name from the fossilized Cockle (Cardiidae) shells that it contains, and it was first described along the Bow River banks by James Hector in 1895.[2] It is present throughout western Alberta and in northeastern British Columbia, and it is a major source of petroleum and natural gas.
  • Montney Formation The formation is composed of siltstone and dark grey shale, with dolomitic siltstone in the base and fine grained sandstone towards the top.[2] The facies is shaley in the north and west of the extent (FortCardium  St. John), silty in the center (Dawson Creek and Pouce Coupe areas) and becomes coarser (sandy) in western Alberta (Valleyview area).
  • Lloydminster & DINA – The Lloydminster Sand is an unconsolidated quartz sand inter-bedded with silt. Thin coal and carbonaceous shale beds usually mark the top.  This sand varies in thickness from 10 – 30 meters. It can be traced from Vermillion to Lloydminster. Two thirds of this formation is heavy oil.
  • Clearwater Formation – The formation is well exposed along the Athabasca River from Brule Rapids to Boiler Rapids and along the Christina River, southeast of Fort McMurray, Alberta.   This formation consists of soft black and greenish grey shales, with some interbedded grey and green sands,  and ironstone concretions. At the base of the formation is a thin glauconitic sand called the Wabiskaw Member.   To the southeast in the Cold Lake area the Clearwater Formation consists of continuous, massive salt and pepper and glauconitic sands and interbedded shales, with bitumen resources.
  • GLAUCONITIC (MANNVILLE GROUP, LOWER CRETACEOUS, SANDSTONE) Glauconitic sandstone is the basal member of the Clearwater Formation in the Mannville group of central and southern Alberta.   Generally, the Glauconitic Sandstone consists of very fine to medium quartz-rich sandstone in eastern Alberta and quartz sandstone intermixed with coarser sandstone in the western part of the province. Commonly, the Glauconite content decreases and clay content increases in southern Alberta, where the unit becomes less marine. Siderite (Fe) spherules are present in places. Interstitial clay and calcareous cement content vary. This unit is widespread in Alberta, extending into B.C.
  • VIKING FORMATION (COLORADO GROUP, LOWER CRETACEOUS, SANDSTONE) – The Viking varies from coarse to fine salt and pepper sand to silt and silty shale. Several sand horizons of  variable thickness may be present with intervening beds of dark grey to black shale. The primary constitute of  the sand is clear quartz. Black chert and glauconite are characteristic throughout, as is siliceous cement.   The Viking “shales out” north and east of a line drawn roughly from Lac La Biche, Alberta through Coleville and Swift Current, Saskatchewan.
  • Woodbend Group reaches a maximum thickness of 700 metres (2,300 ft) in northern Alberta (where reefs were developed), and has typical thickness of 300 metres (980 ft) in southern and central Alberta.[1] It extends laterally from north-eastern British Columbia through Alberta and into southern Saskatchewan and southern Manitoba. Reef build-ups range in size from small mounds to pinnacle reefs and large atoll size reefs and bank developments.
  • BLUESKY FORMATION (LOWER CRETACEOUS SANDSTONE) – The Bluesky is fine to medium grained, usually glauconitic, partly calcareous or sideritic, salt and pepper sandstone with fair porosity. Chert granules and pebbles occur near the top, with thin shale interbedded  throughout. The thickness is 0-46 meters in the Peace River plains subsurface. It thins to the south and southeast.
