Abstract
Since 1999, Japan Canada Oil Sands Limited has been producing heavy oil derived from oil sands in the Hangingstone field, northeastern Alberta, using Steam Assisted Gravity Drainage (SAGD) technology. In order to follow severe environmental policies in Alberta, water recycling is mandatory to operate SAGD that needs a large amount of steam. Injected steam is returned as produced hot water, which is recycled as boiler feed water (BFW). However, the produced hot water contains dissolved organic compounds (DOCs) that give trouble to water recycling system, such as boiler tube leakage. Under the system where DOCs are supplied from oil sand reservoir, our study result for DOCs showed that it is very difficult to remove DOCs from BFW in a technical and/or economical way. To date, the water recycling system has been improved with a concept that DOCs can not be as concentrated in the BFW line as possible. DOCs are concentrated into disposal water, which is injected to a disposal zone. The actual result that water recycling ratio is now over 90% ranks high.

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.
