Hydrocarbon migration detected by regional temperature field variations, Beaufort-Mackenzie Basin, Canada
Bibliographic record
Abstract
Abstract The regional Beaufort-Mackenzie Basin temperature field is characterized using data collected from drill-stem tests and bottom-hole temperature logs. We recognize two thermal anomalies, each of which is associated with a specific geological setting. Elevated temperatures are observed in (1) the western Beaufort Sea, where post-Eocene erosion removed Cenozoic strata and folding is common in a contractional tectonic regime, and (2) along fault zones where upward flow transports heat by advection. Depressed temperatures are observed in Eocene and post-Eocene rapidly subsiding depocenters, with overpressure developed below 3000 m (9843 ft). Older strata along the southeast rifted margin are characterized by a more normal thermal regime. Evidence from anomalously high temperatures in both map and cross-sectional views suggests that fault zones and major regional aquifers accommodate the upward expulsion of fluids from deep overpressured zones. Many significant petroleum discoveries occur in areas where anomalously high temperatures are observed, suggesting that petroleum migration occurs along the same flow networks. Identifying anomalies in the temperature field may therefore be a useful exploration technique.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
