Abstract
Abstract A major factor affecting the hydrate formation and that of gas dissociation is the variation of permeability of the porous media in the presence of gas hydrates. In the absence of reliable experimental data, theoretical and empirical models have been proposed to establish the relationship between gas hydrate saturation and permeability. The effectiveness of a particular permeability model in fitting the measured data has largely been qualitative through graphical analysis. In contrast, this paper introduces a quantitative performance measure to evaluate the effectiveness of a specific model in predicting the measured permeability. Secondly, a novel hybrid model based on the weighted combination of pore-filling and grain coating model is proposed. Permeability measurements from laboratory and field data were used to assess the prediction performance of various permeability models and the proposed hybrid model.

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
