Abstract
The CO 2, CO 2 /CH 4, CO 2 /N 2, and CO 2 /N 2 /CH 4 hydrate equilibria were determined in a stirred high-pressure vessel (autoclave) for temperatures similar to those in depleted natural gas reservoirs in the Alberta portion of the Western Canada Sedimentation basin in Canada. In addition, the equilibrium hydrate formation conditions were also determined by differential scanning calorimetry under a constant pressure of 3200 kPa. Also, experiments with saline water corresponding to 2 and 4 wt % of NaCl solution were used in order to simulate more realistic reservoir conditions. Equilibrium conditions in the autoclave system show a ±40 kPa agreement with the calculated values using CSMGem software. Similarly, the hydrate dissociation temperatures measured with differential scanning calorimetry show ±0.2 K agreement with the calculated values. The increase in salinity was found to shift the equilibrium to less favorable conditions and to decrease the amount of hydrate formed.

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
