Covenant Field: A major oil discovery in the Sevier thrust belt of central Utah
Bibliographic record
Abstract
The overthrust belt of western North America extends from British Columbia to southern Nevada. Large anticlines lie on thrust sheets along the length of this overthrust trend. Many oil and gas fields have been discovered on these structures in Canada, but significant hydrocarbon production in the United States has been primarily limited to a productive salient in southwestern Wyoming and northeastern Utah (Figure 1). On 23 December 2003, Wolverine Gas and Oil-Kings Meadow Ranches well 17-1 drilled into a 487-ft oil column in the Navajo Sandstone in Sevier County, Utah. This new significant oil reservoir is 146 miles southwest of the nearest thrust belt production at Pineview Field in Summit County, Utah. The discovery of what we call Covenant Field is not only a major discovery for Wolverine Gas and Oil but could open up a new Mississippian-sourced oil and gas province in central Utah.

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.
