Abstract
Abstract This paper presents a simulation study on the operational parameters of the ES-SAGD process based on an ES-SAGD lab experiment. A numerical model that incorporated the measured data on key physical properties was validated by detailed history matching of the ES-SAGD lab experiment with n-hexane as the solvent. This numerical model was used to evaluate the performance of ES-SAGD with different operating strategies. The simulation results indicate that oil rate lifting from hexane injection is significant in the early stage of the ES-SAGD process but becomes less effective in the later stage of the process. Improved solvent efficiency can be achieved by adjusting operating parameters such as the start time for steam-solvent co-injection, the duration of the steam-solvent co-injection period and the solvent concentration in the steam-solvent injectant. Results from this study could provide a guideline for the design of a solvent injection strategy for field application of ES-SAGD 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
