Abstract
Abstract The existing models for steam chamber rise rate ignore the effect of water drainage that can result in three-phase flow near the finger/chamber edge. We hypothesize that a steam finger can be divided into three different regions with different pore scale displacement mechanisms. We develop the flux equations for the three regions by assuming 1) negligible oil flow inside the finger, 2) three-phase flow in the transition zone, and 3) single-phase oil flow beyond the transition zone. We further assume that oil flow is coupled to water flow in the transition zone where the dominanat pore-scale mechanisms are double displacement, coalescence, and film drainage. The model results suggest that fast drainage of water in the transition region enhances the oil displacement rate due to the flow coupling. However, increase of the transition zone thickness, due to slow water drainage, decreases the chamber rise rate because of the decrease in the rate of heat conduction to the cold bitumen.

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
