The Dynamic Interplay of Oil Mixing, Charge Timing, and Biodegradation in Forming the Alberta Oil Sands
Bibliographic record
Abstract
Abstract Regional-, field-, and reservoir-scale studies of the petroleum geology, petroleum biogeochemistry, and oil fluid properties of the western Canada oil sands produce the first high-resolution model of oil charge systematics for the oil sands. The sources and alteration history of the Lower Cretaceous and underlying Mesozoic and late Paleozoic oil fields of north-central Alberta (Peace River Arch [PRA] area) were investigated using a very large database of public and in-house data to define the unaltered end-member oils that charged the oil sand reservoirs and to delineate the reservoirs in the study area that are still biologically active today. The complexity of the petroleum systems and variation in source organic facies observed in this study are probably typical of the extremely large petroleum accumjulations that dominate the world's petroleum occurrences.

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.
