Heartland Area Redwater reef saline aquifer CO2 storage project
Bibliographic record
Abstract
The Heartland Area Redwater Project (HARP) for CO2 storage is investigating the technical and economic feasibility of injecting significant volumes of CO2 into the large water-saturated portion of a huge Devonian reef that is capped by a comparatively small oil reservoir, nevertheless the third largest oil pool in western Canada. The reef has a total areal extent of nearly 600 km2, is more than 1,000 meters deep and is up to 275 meters thick. Based on the high water injectivity in the reef, the potential exists to inject sustainably in excess of 1,000 tonnes of CO2 per day per well in the aquifer portion of the reef. Preliminary storage capacity estimates for the aquifer are in the order of one gigatonne of CO2. This storage site has the potential to store CO2 emissions in the order of several tens of Mt/yr from major emitters in central and northeastern Alberta such as oil sands plants, bitumen upgraders, refineries and petrochemical and fertilizer plants. The characteristics of this potential CO2 storage site are presented.

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.
