Abstract

fetched live from OpenAlex

There is public perception that agricultural property value in Alberta is negatively affected by abandoned but unreclaimed oil and gas well sites. This exploratory research examines whether a difference in property values exists between those with reclaimed well sites and properties with abandoned but unreclaimed well sites (i.e., reclamation status). A total of 485 property transfer records from the provincial registry and oil and gas well information from an industry database were used in the research. Stepwise, sequential-search regression was applied to derive an optimized set of potential factors and covariates to predict per-acre agricultural property value. Property sale date, residential density, and agricultural land capability class were the covariates. Property location, well type, and reclamation status were the factors. The data analysis did not support the public perception about reclamation status but did confirm property location and the listed covariates as significant predictors of agricultural property value in Alberta.

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.
