    Description :

      Abstract : This dataset comprises the results (scores) of the aquifer indication analysis at each well location for the Leduc Formation, the combined Swan Hills and Slave Point formations, and the Granite Wash in Alberta. The analysis included water recovery data from drillstem tests, water-production rates, and information on hydrocarbon-water contacts and wet wells (water-saturated) from the AER corporate database. For each data source, scoring criteria were established and a score was assigned at each location. Scores from all data sources at each location were merged, and a final aquifer indication score from 1 (low) to 4 (very high) was assigned.

This digital data product is part of the Geothermal Atlas of Alberta, developed under the Mineral Grant provided by the Government of Alberta.

      Purpose : To provide the results (scores) of the aquifer indication analysis performed to create the aquifer indication layers for the Leduc Formation, the combined Swan Hills and Slave Point formations, and the Granite Wash, respectively, which are one of the input layers in the weighted analysis for geothermal favourability mapping.

Data_Quality_Information :
  Attribute_Accuracy :

    Attribute_Accuracy_Report : Any errors in the original data were carried into this dataset and no systematic checking of attributes from original data sources was undertaken.

The aquifer indication scores provide a semi-quantitative description of the possibility of aquifer existence rather than quantification. It is a reasonable approximation based on the combined existing information of where the formation has shown it can produce water. Due to the data and information often explicitly targeting areas of potential hydrocarbon production, there are biases and limitations associated with this analysis.

  Logical_Consistency_Report : Data from different sources have been collected over decades, by different parties, and using different methods. Data from one well at a given land location may be associated with different well events.

  Completeness_Report : All data records with sufficient information were selected from described sources.
  Positional_Accuracy :
    Horizontal_Positional_Accuracy :

   Horizontal_Positional_Accuracy_Report : The locations of the drillstem tests and wells may be accurate to within millimetres depending on surveying standards at the time of drilling.
    Vertical_Positional_Accuracy :

   Vertical_Positional_Accuracy_Report : The locations of the drillstem tests and oil and gas wells may be accurate to within millimetres depending on surveying standards at the time of drilling.

   Process_Description : 1. Water recovery data from drillstem tests, and water-production rates, acquired from AccuMap, and information on hydrocarbon-water contacts and wet wells (water-saturated) from the AER corporate database were analyzed for each location within the respective geological unit.

2. For each data source, scoring criteria were established and a score was assigned for each criterium at each location.

3. Scores from all data sources at each location were merged, and a final aquifer indication score was assigned as follows:

- 1 (low aquifer indication)

- 2 (medium aquifer indication)

- 3 (high aquifer indication)

- 4 (very high aquifer indication)

Entity_Type_Label: DIG_2024_0015

Entity_Type_Definition: This dataset shows the locations of wells where valuable information from drillstem tests and oil and gas wells, indicating aquifer characteristics, was gathered. Initially, scores were given based on both favourable and unfavourable values. Then, scores from each data source were combined, resulting in a final score for each location. These final scores ranged from 1 (low aquifer indication) to 4 (very high aquifer indication). These scores were then used to create the aquifer indication layer, which is a crucial input for geothermal favourability mapping.
