Description

This dataset is a grid of the thickness of the Haynes aquifer within the Paskapoo Formation. The Haynes aquifer is a regionally extensive body of sand that lies in the bottom part of the Paskapoo Formation. The isopach was created from the modelled results of the average sandiness of 25 m thick slices in boreholes completed within the Paskapoo Formation. Parts of the aquifer are as much as 100 m thick, particularly in the west near the deformation belt and in a region west of the city of Red Deer. The bulk of the unit averages about 50 m in thickness. Given the great range in elevation of the top of the unit, but the relatively uniform thickness of the bulk of the aquifer, we inferred that most of the Haynes aquifer was deposited prior to major deformation with only the western-most parts showing evidence of infill of enhanced accommodation space. Most of the Haynes aquifer is overlain by thick muddy sediments of the Lacombe Member and only outcrops along its eastern edge.

Description

This dataset represents the topography of the top of the Paskapoo Formation, which is also the bedrock topography in the western part of Alberta. We clipped the surface from Alberta Geological Survey's Bedrock Topography of Alberta grid using the areal extent of the Paskapoo Formation shown on Alberta Geological Survey Map 236, Geological Map of Alberta. The dataset is in ESRI ASCII grid format

Subsurface Stratigraphic Picks for the Top of the Foremost Formation (Belly River Group), Alberta Plains (tabular data, tab delimited format)

The dataset includes subsurface stratigraphic picks for the top of the Foremost Formation (Belly River Group) in the Alberta Plains (Townships 1 to 52, Ranges 1W4 to 5W5) made from downhole... More ≫

Description

The dataset includes subsurface stratigraphic picks for the top of the Foremost Formation (Belly River Group) in the Alberta Plains (Townships 1 to 52, Ranges 1W4 to 5W5) made from downhole wireline geophysical well logs. The top of the Foremost was picked at the base of a continuous sandstone or siltstone bed (low-gamma-ray) of variable thickness overlying the Taber coal zone. 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 were examined individually.

Subsurface Stratigraphic Picks for the Belly River Group/Lea Park Formation Transition in East-Central Alberta (tabular data, tab delimited format)

Description

The dataset includes subsurface stratigraphic picks for the interfingering members that define the transition between the Belly River Group and the Lea Park Formation in east-central Alberta (Townships 1 to 62, Ranges 1W4 to 21W4) made from wireline geophysical well logs. Coarsening upwards, siltstone to sandstone-dominated members of the Belly River Group include (from youngest to oldest) the upper Birch Lake, lower Birch Lake, Ribstone Creek, Victoria, and Brosseau members. Interfingering mudstone-dominated members of the Lea Park Formation include the Mulga, Grizzly Bear, Vanesti, and Shandro members. Where the top and base are present, we calculated isochore values for each member. 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 were examined individually.

Description

In 2002 the Alberta Geological Survey initiated a project to scan and digitize water well geophysical logs from Alberta Environment and Sustainable Resource Development (ESRD) water well data holdings. Casual and summer student staff scanned hard copy logs systematically by NTS mapsheet starting with the Cold Lake area. Scanned logs were digitized into Log ASCII Standard version 2 by Divestco Ltd. This data release consists of 8,763 LAS files, comprised mostly of resistivity logs, and a tab delimited index file. About 1% of the LAS files also contain a natural gamma log. The API number (APIN) in the log header refers to Alberta Environment's water well identifier number used at the time the logs were digitized. There are 205 records where the API number starts with 900. We were unable to confidently match the log file surface location to an AENV location for these records. The approximate aerial coverage is from latitude 49 degrees to 56 degrees N and from longitude 110 degrees to...

Description

The dataset includes subsurface stratigraphic picks for the base of the Belly River Group/Wapiti Formation in the Alberta Plains (Townships 1 to 94, Ranges 1W4 to 14W6) made from wireline geophysical well logs. In general, the pick was made at the base of the lowest sandstone bed (overlying the Pakowki or Lea Park Formation) that was overlain by coal. If coal is absent, the pick was made at the base of the first sandstone. We screened the well data 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 were examined individually.

Description

This GIS dataset depicts an estimate of average annual groundwater recharge in the Edmonton-Calgary corridor based on hydrological water budget analysis using climate and hydrometric data from Environment Canada, the Water Survey of Canada, and Alberta Environment and Sustainable Resource Development. This average annual groundwater recharge grid was generated to assist in building steady-state numerical groundwater flow models for large regions within the Edmonton-Calgary Corridor.

Description

This polygon dataset is part of the three-dimensional (3-D) hydrostratigraphic model of the Sylvan Lake sub-basin in the Edmonton-Calgary Corridor, central Alberta. This dataset provides the areal distribution of greater than or equal to 0.60 net-to-gross sandstone values for the Paskapoo Formation - Lower Composite Slice, defined by an analysis of normalized oil and gas well digital gamma-ray logs to produce discrete slices of net-to-gross sandstone distribution within the Paskapoo Formation. The zonated Paskapoo Formation - Lower Composite Slice is in ESRI shapefile format for input into a groundwater flow model. This dataset supplements Alberta Geological Survey (AGS) Open File Report 2014-10, which includes a full description of the steps taken to produce the dataset.
