One of the goals of the PBR pilot is to encourage companies in the unconventional play area to work together on plans for surface development to minimize the numbers of facilities and surface impacts. This dataset is one of a series created using earth observation imagery to assess surface change caused by energy exploration. The PBR area extends from Twp. 52, Rge. 7, W 5th Mer. to Twp. 70, Rge. 5, W 6th Mer., covering the towns of Edson, Fox Creek, Mayerthorpe, Whitecourt, Swan Hills, and Valleyview. Landsat multispectral imagery for 2010 and 2011 and Land Use and Land Cover (LULC) classification data derived from 2011 were used to produce this dataset. The LULC changes include vegetation loss from anthropogenic disturbances, such as infrastructure related to oil and gas exploration, forestry and agriculture, and vegetation recovery from these disturbances. This digital data release contains the vegetation recovery data, classified into 6 classes: 1 - shrub land, 2 - grassland, 3 - agricultural areas, 4 - coniferous forest, 5 - broadleaf forest and 6 - mixed forest.2020-04-30T04:09:58.644159+00:00https://open.alberta.ca/dataset/1cebf3b4-0bf7-4cda-a20a-1783e14ee0ecAnnual Vegetation Recovery Classification Results of the Play-Based Regulation Pilot Study Area Derived from 2011-2012 Landsat imagery (Image data, Tiff format)2024-03-28T02:50:57.598276+00:00In 2014, the Alberta Energy Regulator (AER) initiated a Play-Based Regulation (PBR) pilot project as a step towards implementation of the Unconventional Regulatory Framework.

This dataset consists of previously published information from Alberta Geological Survey (AGS) maps and reports, as well as new data for which the quality has been assessed in order to apply a quality-weighting approach prior to modelling the bedrock topography surface. It is the data used to produce AGS Map 602, Bedrock Topography of Alberta. Explanatory notes, references, and data sources appear on a supplementary page to accompany Map 602. These notes describe the distribution of physiographic terrain elements of the bedrock surface across Alberta, and the sources and quality of the data that were used to interpolate this surface.2020-04-30T04:11:49.549602+00:00https://open.alberta.ca/dataset/a0231a3d-b478-4a0b-99c8-f48a011b2906Bedrock Topography of Alberta (gridded data, ASCII format)2024-03-28T02:51:02.077206+00:00The bedrock topography of Alberta is the surface of the top of Upper Cretaceous and Paleogene bedrock, and reveals geomorphic features created by Paleogene to Recent river systems and Quaternary glaciation. This grid is a computer-generated geostatistical model of the bedrock topography of Alberta using previously published information from Alberta Geological Survey (AGS) maps and reports, as well as new data. The quality of this data has been assessed and then a quality-weighting approach was applied to the dataset prior to interpolation. The surface was modelled using a 500m x 500m grid cell spacing, and as such should not be used for local scale studies. This grid represents the surface portrayed in AGS Map 602, Bedrock Topography of Alberta, and this grid will continue to be updated as part of the Alberta Geological Framework project. Explanatory notes, references, and data sources appear on a supplementary page to accompany Map 602. These notes describe the distribution of physiographic terrain elements of the bedrock surface across Alberta, and the data sources and geostatistical methods used to interpolate this surface.2020-04-30T04:11:52.256874+00:00https://open.alberta.ca/dataset/29430344-0807-4b40-971d-4ad6f207427bCompilation of In Situ Stress Data from Alberta and Northeastern British Columbia (tabular data, tab delimited)2024-03-28T02:51:02.224648+00:00This 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. Regional-scale studies of the stress regime indicate that in southern and central Alberta the vertical stress (Sv) is the largest principal stress. The Sv magnitude is determined from the overburdened load and is calculated by integrating the bulk density log from ground surface to the depth of interest. This dataset contains 724 vertical stress gradient measurements from 126 wells in Alberta. The minimum horizontal stress (Shmin) can be evaluated using a variety of tests. While leak-off tests and fracture breakdown pressures have been used in the past for estimating the magnitude of the Shmin, mini-fracture tests (also known as DFITS) are currently considered a more accurate and consistent method. This dataset includes only mini-fracture test data, consisting of 106 minimum horizontal stress gradient measurements in 83 wells. Alberta was one of the first regions in the world where stress mapping began, originating in the pioneering 'borehole breakout' developments of Dr. Bell from the Geological Survey of Canada in Calgary and Dr. Gough from the University of Alberta. The Shmin orientations can be determined from borehole breakouts, which are spalled cavities that occur on opposite walls of a borehole. This dataset contains 214 stress orientation measurements from 133 wells.2020-04-30T04:11:54.712665+00:00
