Abstract
Abstract Shell runs a Steam Assisted Gravity Drainage (SAGD) operation at the Orion field in Alberta, Canada. Pressure drops during bitumen and water recovery can lead to precipitation and buildup of scales which can plug up well equipment and lead to an increase in differential pressure and lower production. Early attempts to remove such blockages with high pressure steam or salinity-altering brine injections resulted in transient returns to normal operations but with diminishing returns. Acid treatments to dissolve the scale encountered problems with corrosion and an inability to handle the discovery of the presence of acid insoluble scales. Alterations to the operating conditions such as pH along with the addition of a chelating agent, EDTA, were successful in treating both types of scales. As a result, differential pressures and steam to oil ratios decreased while oil production grew. This treatment was extremely cost-effective and payout was on the order of a few days.

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
