This dataset evaluates the sandstone-hosted uranium potential of Alberta. An Alberta Geological Survey database of oil and gas well logs were queried to identify wells with gamma values greater than 300 API (American Petroleum Institute units). An algorithm written for this analysis queried more than 48 000 gamma ray logs from more than 22 000 wells. Of those, 11 476 readings greater than 300 API, within the upper 500 metres, were found in 6176 wells.

This is a 1000 m cell-sized raster dataset of the upper surface of the Lacombe Member aquitard, modelled from the >65% silt and clay point data derived by depth-slice analysis of well-log data. Alberta Geological Survey Bulletin 66 provides details on this grid dataset. The dataset is in ESRI ASCII grid format.

This GIS dataset depicts the result of a geostatistical model of the bedrock topography in Alberta. This model is based on water-well litholog data, stratigraphic picks made on oil and gas petrophysical logs, data derived from digitized contour interpretations on bedrock topography maps, including bedrock outcrop locations and the 60 m grid-spaced Shuttle Rader Topography Mission digital elevation model. These data comprise the raster surface of Alberta Geological Survey Map 550, Bedrock Topography of Alberta, Canada.

The base of the Paskapoo Formation is unconformable with the underlying Scollard Formation. Alberta Geological Survey differentiates the Paskapoo Formation from the underlying Scollard Formation by the first thick sandstone above the uppermost coal seam of the Ardley coal zone. We defined 'thick sandstone' to be 5 m or more thick. This dataset contains the gridded results of the structural surface of the base of the Paskapoo Formation modelled from stratigraphic picks of the >5 m sand above the Scollard Formation coal from oil and gas industry gamma-ray logs.

The dataset includes subsurface stratigraphic picks of the Milk River 'shoulder' in the Alberta Plains (Townships 1 to 73, Ranges 1W4 to 2W6) made from wireline geophysical well logs. The Milk River 'shoulder' is an informal term often used to refer to a distinctive 'shoulder' (deflection) on resistivity, sonic, density, and porosity logs. The Milk River 'shoulder' corresponds to the top of the Milk River Formation in southernmost Alberta, where it represents juxtaposition between paralic deposits of the underlying Deadhorse Coulee Member of the Milk River Formation and overlying marine shale of the Pakowki Formation. It is characterized by a leftward deflection (decreasing resistivity) upwards across the contact, forming the distinctive 'shoulder signature'.

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.

Stratagex Ltd was contracted by the AGS in 2001 to compile a catalogue of all existing ground and airborne geophysical survey data contained in the archived mining assessment reports of the AGS, supplemented where possible with information on non-exclusive and proprietary surveys from exploration industry and other sources. This data set shows the airborne survey locations and detailed information about the survey including: Type of survey flown [fixed wing or helicopter. barometric (constant elevation) or drape (topographic contour following), Year of data acquisition and contractor, Description of the system flown [any one or combination of magnetics, VLF-EM, radiometrics, time domain electromagnetics (TDEM), frequency domain electromagnetics (FEM)]., Survey specifications (flying height, line direction, line separation, tie line spacing and direction), Location of the survey (corner co-ordinates of the survey area in UTM and latitude and longitude), Outline of the actual survey coverage (plan map of survey block outline on planimetric base), Owner of the data at time of acquisition (and contact person if available), Assessment of data quality (where possible, based on the maps or profiles made available by the Contractor/Mining Company who holds the data), Availability of the data for use or acquisition by the AGS (for compilation, resale, in-house research), Media and format that data is available on (paper, digital images, raw digital data, etc.), Asking price for acquiring the data (if available) and the conditions under which it would be made available.

This is a raster dataset of the thickness of the Paskapoo Formation. It is a derived dataset created by the subtraction of the base of the Paskapoo Formation from the top of the formation, which in the western part of Alberta is also the bedrock topography. The gridded isopach data cover only the undeformed part of the Paskapoo Formation that extends west to the front ranges of the Rocky Mountains. The isopach data do not include those parts of the formation affected by tectonic folding or thrusting.

This dataset maps the thickness of the Lacombe aquitard as defined by outputs of a 3-D model of sandiness in the Paskapoo Formation. The Lacombe aquitard consists of >65% non-sandy material in stacked, 25 m thick slices above the base of the Paskapoo Formation.
