Description

This digital dataset is the compilation of an analysis of the in situ stress regime in several regions of Alberta and northeastern British Columbia conducted by Dr. Sebastian Bell under a contract with the Alberta Geological Survey from 1999 to 2004. The dataset includes both new and previously published estimates for vertical stress gradients, minimum horizontal stress gradients, and stress orientation. Understanding the state of stress in the subsurface has always been important in the development of energy resources. The recent development of unconventional oil sand and low permeability hydrocarbon deposits, waste fluid disposal, greenhouse gas sequestration, and potential geothermal energy extraction all require knowledge of the state of stress to operate safely and economically. A lack of understanding of the state of stress in a given project area has the potential to negatively affect the economics of such projects and may expose operators to increased liabilities.

Surficial Geology of the Calgary-Lethbridge Corridor (GIS data, polygon features)

Description

This GIS dataset is a compilation of existing surficial map information for the Calgary-Lethbridge Corridor area tiled into one layer. It is suitable for presentation and use at 1:250 000 scale.... More ≫

Description

This GIS dataset is a compilation of existing surficial map information for the Calgary-Lethbridge Corridor area tiled into one layer. It is suitable for presentation and use at 1:250 000 scale. The dataset was prepared by appending existing GIS datasets into one layer with a standard attribute table. These datasets were then compared against surficial maps for which GIS data were unavailable. Lastly, polygon boundaries were modified to agree with the surface topography as represented by a digital elevation model (DEM) with a grid cell size of 25 metres. Data sources included published Alberta Geological Survey and Geological Survey of Canada maps and the Agricultural Regions of Alberta Soil Inventory Database Version 4.0. Legend information for each polygon was translated by the author into the standard schema. This dataset contains the polygon features of Alberta Geological Survey Map 579, Surficial Geology of the Calgary-Lethbridge Corridor, and has been exported in shapefile...

Surficial Geology of the Calgary-Lethbridge Corridor (GIS data, line features)

Description

This GIS dataset portrays the distribution of glacial landforms within the Calgary-Lethbridge Corridor area, based on the compilation of existing government survey mapping and research literature,... More ≫

Description

This GIS dataset portrays the distribution of glacial landforms within the Calgary-Lethbridge Corridor area, based on the compilation of existing government survey mapping and research literature, supplemented by new analysis of remote sensing data. The original line features have been modified where necessary for map production at 1:250 000 scale. This dataset contains the line features of Alberta Geological Survey Map 579, Surficial Geology of the Calgary-Lethbridge Corridor, and has been exported in a shapefile format for public distribution.
