Release Notes

Each subsection below contains release notes for a specific 3W Dataset version. Differences from the immediately previous version are highlighted.

1.0.0

Release: July 1, 2019.

This was the first published version, which is fully described in this paper.

1.1.0

Release: December 30, 2022.

Highlights:

  1. New instances were added as follows:
    • 1 instance of event type 7.
  2. Instances were removed due to issues identified as follows:
    • 3 instances of event type 0;
    • 1 instance of event type 5;
    • 3 instances of event type 8, when compared to what is described in the paper A realistic and public dataset with rare undesirable real events in oil wells published in the Journal of Petroleum Science and Engineering (link here).
  3. Normal periods of certain instances with anomalies were increased as possible. We tried to have instances with minimum normal periods of 1 hour;
  4. Names of certain files with instances have changed due to increased normal periods;
  5. Labels in some real instances were adjusted by experts;
  6. All values of some variables in some real instances were corrected due to corrections in historian systems' tag configurations;
  7. Certain variable values ​​have undergone minimal change due to different rounding;
  8. The 3W Dataset's main configuration file (dataset.ini) was updated.

1.1.1

Release: April 09, 2023.

Highlights:

  1. Issue #60 was resolved;
  2. Issue #65 was resolved;
  3. Certain variable values ​​have undergone minimal change due to different rounding;
  4. The 3W Dataset's main configuration file (dataset.ini) was updated.

2.0.0

Release: July 25, 2024.

Highlights:

  1. All instances are now saved in Parquet files (created with the pyarrow engine and brotli compression);
  2. Reduction in disk space occupied by the 3W Dataset of 3.15 GB (from 4.89 GB to 1.74 GB);
  3. Real and simulated instances of type 9 were added;
  4. Several instances of types 0, 3, 4, 5, 6 and 8 were added;
  5. Another 24 real wells were covered with new real instances (now 42 real wells are covered);
  6. Some real instances, mainly of type 1, were removed;
  7. 1 variable was removed (T-JUS-CKGL);
  8. Another 20 variables were added (there are now 27 variables);
  9. Another label referring to well operational status was added;
  10. Normal periods in several real instances with unwanted events were extended;
  11. All labeling gaps in real instances were eliminated (all observations were labeled);
  12. Conversions between measurement units in several instances were corrected;
  13. Labels in several real instances were adjusted by experts;
  14. All values of some variables in some real instances were corrected due to corrections in historian systems' tag configurations;
  15. Certain variable values ​​have undergone minimal change due to different rounding;
  16. The 3W Dataset's main configuration file (dataset.ini) was updated.
