Stratigraphic and Lithological Picks of the Uppermost Geological Units in the Athabasca Oil Sands Area (tabular data, tab-delimited format)

Description

This dataset has stratigraphic and lithological picks of the upper bedrock and Quaternary geological units in the Athabasca Oil Sands Area extending north from Cold Lake to the Fort McMurray... More ≫

Description

This dataset has stratigraphic and lithological picks of the upper bedrock and Quaternary geological units in the Athabasca Oil Sands Area extending north from Cold Lake to the Fort McMurray region. The picks were compiled from the mid-1970s to 2006 to construct maps of the subsurface distribution, structure, topography and thickness of near-surface bedrock and Quaternary stratigraphic units. Alberta Geological Survey staff, as well as staff from industry and other government departments, interpreted the data.

Subsurface Stratigraphic Picks for the Top of the Oldman Formation (Base of Dinosaur Park Formation), Alberta Plains (tabular data, tab-delimited format, to accompany Open File Report 2011-13)

Description

The dataset includes subsurface stratigraphic picks for the top of the Oldman Formation (base of the Dinosaur Park Formation) in the Alberta Plains (Townships 1 to 47, Ranges 1W4 to 5W5) made from... More ≫

Description

The dataset includes subsurface stratigraphic picks for the top of the Oldman Formation (base of the Dinosaur Park Formation) in the Alberta Plains (Townships 1 to 47, Ranges 1W4 to 5W5) made from wireline geophysical well logs. The dataset supplements Alberta Geological Survey Open File Report 2011-13, which describes the methodology used to make the picks. Well data were screened to detect errors resulting from deviated wells, as well as incorrect ground and kelly bushing elevation data. We used statistical methods to identify local and regional statistical outliers, which we examined individually.

Water Geochemical Data, Saline Aquifer Project, 2011 (tabular data, tab delimited format)

Description

In 2011, for the Alberta Geological Survey Saline Aquifer Mapping Project, we collected and analyzed 40 water samples from oil wells producing from geological units, including the Cardium, Viking,... More ≫

Description

In 2011, for the Alberta Geological Survey Saline Aquifer Mapping Project, we collected and analyzed 40 water samples from oil wells producing from geological units, including the Cardium, Viking, Mannville, Glauconitic, Ellerslie, Nordegg, Banff, Wabamun, Nisku and Leduc, within approximately 200 km of Edmonton, Alberta. We analyzed filtered water samples for pH, density and specific conductance. oxygen, hydrogen and strontium isotopes. and dissolved constituents, including sodium, potassium, calcium, magnesium, barium, strontium, lithium, chloride, bromide, sulphate, sulphide, silica and inorganic carbon.

Description

In 2010, for the Alberta Geological Survey Saline Aquifer Mapping Project, we collected and analyzed 38 water samples from oil wells producing from geological units, including the Glauconitic, Ostracod, Ellerslie, Banff, Wabamun, Nisku, Leduc and Cooking Lake, within 100 km of Edmonton, Alberta. We analyzed filtered water samples for pH, density and specific conductance. oxygen, hydrogen and strontium isotopes. and dissolved constituents, including sodium, potassium, calcium, magnesium, barium, strontium, lithium, iron, manganese, chloride, bromide, sulphate, sulphide, silica and inorganic carbon.

Description

This digital dataset represents the modelled outputs of the three-dimensional distribution of sandiness in the Paskapoo Formation, Alberta, Canada. Sand-abundance values were determined from log analysis of water-well lithologs and petroleum exploration downhole-geophysical logs, specifically gamma-ray logs. We derived the sandiness values by calculating the average sandiness in 25 m thick slices above the base of the Paskapoo Formation in a borehole and by assigning the average value (P50) to the midpoint of each slice interval. Alberta Geological Survey Bulletin 66 provides detailed descriptions of the methodology. We tested the borehole sand-abundance values in a 3-D variogram prior to kriging in a regular block model consisting of cells with dimensions of 1000 m on the x and y planes and 25 m in the z (elevation) direction. Values of modelled sandiness range from 0 (absence of sand) to 1 (100% sand) and are assigned elevations based on two datums: 1) a stratigraphic level...
