Organic petrology and vitrinite thermal maturation profiles for eight Yukon petroleum exploration wells in Eagle Plain and Liard basins
Bibliographic record
Abstract
Eight Yukon petroleum exploration wells were sampled for organic petrology and vitrinite reflectance thermal maturity. Seven wells are located in Eagle Plain, northern Yukon, and one is from Liard Plateau in southeastern Yukon. Where possible, the stratigraphic tops used in the interpretations reflect the currently available biostratigraphy. Kerogen type is dominated by marine to marginal marine, Type II and Type II/III; and pyrite is commonly found in association with the kerogen. Over much of Eagle Plain basin, Late Devonian to Albian strata are within the oil window. Higher reflectance values, into the dry gas zone at depth, are recorded toward the basin margins where older rocks are exposed. Absence of a maturity discontinuity at the sub-Mesozoic unconformity indicates that the thermal maximum post-dates Albian and predates early Tertiary exhumation. In the Beaver YT G-01 well in Liard Basin, the Late Devonian succession lies within the wet gas to dry gas windows whereas the Carboniferous section is within the oil generation window.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
