Abstract
Summary A comprehensive rock physics and AVO feasibility study, where we combine burial and rock physics modelling, has been conducted for the Tablelands and North Tablelands area, offshore Newfoundland. The burial history was assessed in 3D from seismic velocity information, calibrated to selected wells in the area. There is a natural ambiguity between the temperature and burial histories. We therefore introduce the term “pseudo-uplift” referring to deviations from normal compaction for a given temperature gradient. The “pseudo-uplift” cube can be used to constrain 3D rock physics and AVO feasibilities away from the selected wells within a selected area of interest. We model different scenarios, including a “pessimistic” one (P90) with respect to reservoir quality and fluid sensitivity, an “optimistic” one (P10), and an “expected” one (P50). These AVO scenario-cubes could be used to screen, rank and derisk leads and prospects in the area from real AVO data.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
