Description:
Abstract:
The Montney Formation is a significant source of unconventional production of hydrocarbons in Alberta and a target for further drilling. This digital data release contains hydrogen sulphide (H2S) concentration data from gas analysis results attributed to the Montney Formation and adjacent Belloy and Doig formations in Alberta, submitted to the Alberta Energy Regulator by industry.
Purpose: To disseminate H2S concentration data for the Montney Formation and adjacent formations in Alberta.

Data Quality Information:
Attribute Accuracy:
Attribute Accuracy Report:
Many of the nonzero values in the H2S_conc field are 0.0001 (0.01% or 100 ppm). This is the analysis threshold for many of the tests. The minimum nonzero value in the is 1.0x10e-6, or 1 ppm. This is the analysis threshold for some of the tests. More precise measurements of trace amounts of H2S may be available elsewhere.
Logical Consistency Report:
The criteria used to filter the data are as stated in the Process Step section, and only cursory checks have been made on the geospatial position of the reported tests. Some of the tests may be from deviated or horizontal wells, causing discrepancy between the reported top and base depths of the tested interval (measured along the length of the borehole) and their true vertical depths, and between the surface and bottom hole latitude/longitude and the actual coordinates of the tested interval top and base in the subsurface. Directional drilling survey data (if available) should be used to determine the correct geospatial position of the tested intervals.
Completeness Report:
The data are current as of May 20, 2020. The query results were filtered as specified in the Process Step section.
Positional Accuracy:
Horizontal Positional Accuracy:
Horizontal Positional Accuracy Report:
Some of the samples may have been taken from horizontal or deviated wells, causing a discrepancy between the surface and bottom hole latitude/longitude and the actual coordinates of the tested interval top and base in the subsurface. Directional drilling survey data (if available) should be used to determine the correct geospatial position of the tested intervals.
Vertical Positional Accuracy:
Vertical Positional Accuracy Report:
Some of the samples may have been taken from horizontal or deviated wells, causing a discrepancy between the reported top and base depths of the tested interval and their true vertical depth. Directional drilling survey data (if available) should be used to determine the correct geospatial position of the tested intervals.

Process Step:
Process Description:

A Python script was used to run an SQL query on the AER corporate data holdings and perform basic data formatting and filtering. The conditions and filters used were as follows:

- Gas tests from wells containing the words 'MONTNEY', 'DOIG', 'BELLOY', or 'TRIASSIC' in their Well Licence Purpose field.

- Any tests from wells with confidential status were removed.

- Any tests with null values in the Reported H2S field were removed.

- Wells that are injection or observation wells based on the Well Licence Purpose or Type fields were removed.

- Samples based on recombination of fluids were removed.

- Any tests with quality flagged as Poor were removed.

- Samples from wells south of 52.5 degrees N latitude were removed.

- Samples from east of 115.2 degrees W longitude were removed.

- Samples with a base depth of less than 1000 m were removed.

- Samples from east of 115.2 degrees W longitude were removed.

- Samples with a tested interval base depth of less than 1000 m were removed.

These operations produced a total of 17 434 gas analysis tests associated with 5100 unique well identifiers (UWIs).
