2-D Numerical Modeling of CO2 Storage in the Devonian H2S Containing Nisku Aquifer in the Wabamun Lake Area (Alberta, Canada)
Bibliographic record
Abstract
The Devonian Nisku aquifer has been identified as a suitable CO 2 storage site in the Alberta Basin, but this aquifer contains significant amounts of H 2 S. Numerical simulations were performed to investigate the impact of dissolved H 2 S in the brine on the behavior of the injected CO 2 . No major differences in geochemical reactions were observed between model runs with and without H 2 S. Extensive dolomite dissolution was observed in both model runs, which caused a minor increase in porosity and permeability of the aquifer. The majority of the injected CO 2 was trapped in the Middle Nisku as a free supercritical phase and the rest was dissolved in the brine.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
