Exploration and Development of the Winnipeg/Deadwood Deep Gas Play along the Nesson Anticline
Bibliographic record
Abstract
In the early 1990s, Amerada Hess Corporation began completing a series of deep gas wells in the Black Island (Winnipeg Group) and upper Deadwood Formations along the Nesson and Antelope Anticlines (fi g. 1). Primarily targeting sandstone intervals within the upper Black Island Formation (fi g. 2), 13 deep gas wells have been completed in the Winnipeg/Deadwood along the Nesson and Antelope Anticlines to date, 12 by Amerada Hess Corporation (now Hess Corporation). With individual well production totals ranging from just 2,073 barrels of oil equivalent (BOE) to over 3.5 million BOE (~20 billion cubic feet, BCF dry gas), these 13 wells have cumulatively produced over 16 million BOE of dry gas (Nesheim, 2012). Peak production took place in April of 1997 when over 145,000 BOE (~0.8 BCF gas) were produced from the Winnipeg/Deadwood system (fi g. 3). With most of Amerada Hess’s deep gas wells completed in the middle 1990s, their success was partly overshadowed by the developing horizontal fractured Bakken upper shale play, the discovery and exploration of the prolifi c Lodgepole mounds, and the Red River Horizontal B discovery.

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.
