Stratigraphy, sedimentology and petroleum potential of the Upper Devonian Duperow Formation, southwest Manitoba
Bibliographic record
Abstract
The Upper Devonian (Frasnian) Duperow Formation in the Williston Basin consists of cyclical deposits of carbonate rocks and evaporites deposited in the semi-restricted Duperow Embayment. The formation can be divided, in ascending order, into the Saskatoon, Wymark and Seward members. Three lithofacies associations (subtidal, intertidal and supratidal/sabkha) comprised of nine lithofacies, representing a semi-restricted interior platform setting, are recognized in this study. These lithofacies include diagenetic features representing alteration in marine, burial and meteoric environments. Thin organic-rich laminae throughout the Wymark Member have good generative potential for oil and/or gas but are thermally immature. Dolomitized units of the Saskatoon and Wymark Members have good reservoir potential. The best potential for conventional petroleum plays exists in possible structural traps related to salt dissolution in the Prairie Evaporite and block faulting along the Birdtail-Waskada Zone, as well as stratigraphic traps related to laterally and vertically variable dolomitization.

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.
