Description:
Abstract:

This data release contains water chemistry data used to create a total dissolved solids (TDS) map of the Keg River / Winnipegosis hydrostratigraphic unit (HSU). The data were acquired from publicly available formation water chemistry data from oil and gas well drillstem tests (DST) and production fluids, as well as industry monitoring wells accessed through environmental impact assessments reports.

Data have been processed, relevant records selected, and outliers removed to compile this dataset.

Purpose: For computer display, query, and modelling of TDS distribution for the Keg River / Winnipegosis HSU.

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. All attributes in this data set are as received from the data source. The total dissolved solids (TDS) values are calculated from other fields, and do not contain any decimal places. Calculation of TDS is dependent on the availability of specific ions at the time of testing and the generally accepted standard for displaying TDS is a whole number.
Logical Consistency Report:
Water chemistry data used in this dataset have been collected over decades, by different parties, and using different methods.
Completeness Report:
All data records within the Keg River / Winnipegosis HSU with sufficient information were selected from described sources. Null values are reported as -9999.
Positional Accuracy:
Horizontal Positional Accuracy:
Horizontal Positional Accuracy Report:
The locations of the oil and gas wells may be accurate to within millimetres depending on surveying standards at the time of drilling.
Vertical Positional Accuracy:
Vertical Positional Accuracy Report:
The mid-point of the sampled interval is a calculated value and its accuracy is dependent on the accuracy of the measured depths and elevations provided in the well header. For the oil and gas wells, the well elevations and locations are surveyed in, so accuracy will be to the same significant digits provided by the source, even though there may be considerable uncertainty as to where the sample actually came from. The location of the sampled interval in oil and gas wells may be accurate to within millimetres in accordance with surveying standards at the time of drilling.

Process Step:
Process Description:

Process steps for selection of formation water analyses from oil and gas wells:

1. Records containing depth of tested interval information were selected;

2. The tested interval length was constrained to less than or equal to 50 m;

3. The acceptable charge balance error was constrained to ±10%;

4. Samples labelled as “incomplete analysis" were excluded;

5. Records were allocated to the Keg River / Winnipegosis HSU based on the depth information for the tested interval;

6. Records with tested intervals straddling the top or bottom of the Keg River / Winnipegosis HSU were excluded, unless they were from wells in data-poor areas and it was verified that less than 30% of the tested interval extended into the formation directly above or below the HSU, but not into any other formation;

7. In case of collocated data, the most representative sample was selected, or averaging of TDS values was done;

8. The concentration of total dissolved solids (TDS) was determined either by summing the concentration of major constituents (if available), or by using the TDS values as reported in the source dataset (if major constituents were not available)

The remaining formation water analyses were subjected to additional screening to identify potential contamination of the formation water by drilling fluids such as acid water, corrosion inhibitors, mud filtrates, and alcohols.

Process steps for selection of formation water analyses from compiled sources:

1. Any records where the sampled interval was identified as the Keg River / Winnipegosis HSU were included in the initial dataset.

2. Filtering was done based on the information provided in the reports.

The final dataset includes only those records that were used in the production of the final TDS surface.
