Abstract

fetched live from OpenAlex

The dataset contains methane emission rate (mg/hr) measurements collected from non-producing wells between 2018 and 2023 across five Canadian provinces (Alberta, British Columbia, Ontario, Quebec, and Saskatchewan). All measurements were performed using the static chamber methodology, as described in the Supporting Information (SI-3) of the related publication. In Alberta and Saskatchewan, we measured the wellhead infrastructure and the surface casing vent separately (see column “Component”). We include the well attributes investigated in our study (i.e., type, status, operator, wellbore deviation, well depth (meters), age (years) and well density (wells/km2)). Refer to the Supporting Information (SI-1) of the related publication for more details on well attribute definition and classification.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
