Abstract
Over the past 50 years, the SE Saskatchewan portion of the Williston Basin, has produced mainly from Mississippian Subcrop, Structural, and Stratagraphic play types. In 1995, Bob Yurkovich of Berkley Petroleum made an Ordovician Red River Yeoman discovery which re-ignited exploration in the Devonian to Cambrian section of the Williston Basin. Since that time at least 20 additional significant discoveries have been made in the Red River Yeoman beds. Since that time additional horizons, which had not previously been produced in the Canadian portion of the Williston Basin, have had significant discoveries. The Ordovician Winnipeg sand (55-65 degree API sweet oil) and the Devonian Duperow (Leduc eq.) (42 degree API sweet oil) have both produced with IP's over 100 m3/d and cumulative production of over 30,000 m3 in less than 3 years. Some of the cores of these zones pose interesting questions. For example, the Winnipeg sand is a regional fine to medium grained sand that seems to be porous and very permeable (Darcy permeability) over the entire SE Saskatchewan portion of the Williston Basin. Yet locally, over some basement features, the Winnipeg sand is rendered nearly impervious by apparent pressure solution. The Duperow discoveries vary laterally from a regional lime mudstone to possible localized hydrothermal dolomitization along fault trends. The dolomitization creates vugs large enough to drop a pen thru the core. These features along with new pool discoveries in the Mississippian Bakken, Devonian Birdbear (Nisku eq.), and Devonian Winnipegosis (Keg River eq.) all tend to be localized above or beside possible granitic basement intrusives. A core was taken of basement from the Froude Red River Yeoman discovery well.

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.
