Seismic characterization of the Nisku Formation in the Wabamun area, Alberta, Canada for large‐scale CO <sub>2</sub> sequestration
Bibliographic record
Abstract
Seismic characterization of the Devonian Nisku Formation in the Wabamun area, Alberta, Canada has revealed two primary groups of anomalies. The first group is interpreted to be footprints of geological discontinuities which are induced by dissolution and karsting in a geologic formation shallower in the stratigraphy. Even though there is no evidence to indicate that the integrity of the Nisku Formation or the overlying caprock has been compromised, such geologic discontinuities should be taken into consideration if supercritical CO2 were to be injected into the Nisku Formation. The second group is interpreted to be due to contrasts in lithology and/or porosity of the Nisku Formation. This interpretation is supported by constraints provided by well control and by seismic modeling. Finally, our analysis has identified favorable low-impedance, potentially high-porosity, locations that could be developed for a CO2 injection site.

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.
