Overpressure conditions and reservoir compartmentalization on the Scotian Margin
Bibliographic record
Abstract
Overpressure has been identified as a serious risk element in several offshore basins around the world including the Scotian margin; it has been mapped on the Scotian margin at a low resolution but the causes for overpressure have not been resolved. Previous work (Yassir and Bell, 1994; Wade, MacLean and Williams 1995; Wielens 2003; Play Fairway Analysis 2012) indicated overpressure on the Scotian margin was variable and not readily predictable. Negative aspects and unknowns of overpressure are it can occur with similar magnitude at varying depth in wells in the same field, and may not be related to specific formations or burial depths, formation temperature and hydrocarbon maturity. High pressures exceeding the expected hydrostatic pressures are present in some wells but not in others; the regional pressure gradient and distribution outside the wells is unknown. A positive aspect of overpressures is they are recognized as a potential indicator element for active hydrocarbon systems.

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.
