Abstract
Abstract In SAGD, steam is injected into a bitumen bearing oil sands formation. Steam temperature ranges from about 200 to 260°C and at these temperatures, bitumen undergoes aquathermolysis yielding acid gases such as hydrogen sulphide and carbon dioxide. SAGD simulation models in the literature often account for spatial heterogeneity of the geology and oil composition and heat transfer, multiphase flow, gas solubility effects, and viscosity variations with temperature, however, none account for the chemistry of SAGD. Here, we consider aquathermolysis reactions to understand the reactive zones in the SAGD process and how the process generates acid gases via aquathermolysis. The results show that SAGD is both a physical and chemical-reactive process.

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 it
