Development and Characterization of a Geostatic Model for Monitoring Shallow CO2 Injection
Bibliographic record
Abstract
A 25 sq. km static geomodel was constructed for shallow injection into the 7 m thick Basal Belly River Sandstone at 300 m depth in Newell County, Alberta. Effective porosity and intrinsic permeability were calibrated to six core laboratory analyses. The regressional shoreline sandstone has effective porosity of 11% and intrinsic permeability of 0.57 mD. Dynamic simulation was completed on the P10-50-90 static cases for multiple injection scenarios, totalling approximately 3250 t/CO2 over a five-year period. The evolution of the CO2 plume was observed at one-year during injection and five-years during injection, as well as the one-year and ten-year mark for the post-injection period. The final ten-year post-injection result simulated a laterally extensive plume, expanding to 350 m in diameter and 20 m of vertical migration into the caprock interval. The target interval proves to be an ideal reservoir, and the seal interval predicts containment over a ten-year post-injection period.

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.
