Abstract
Abstract The total cost of corrosion in the oil and gas industry is an often overlooked subject when evaluating the impact of an upset or failure due to corrosion. Costly issues can arise when as little as a single piece of equipment is not designed to properly mitigate corrosion. Not only is there a need to replace the failed piece of equipment but there are many other costs to consider, including, but not limited to: environmental and cleanup costs, safety related costs, unnecessary corrosion inhibition costs, and costs associated with potential future failures at other projects that have utilized similar designs and processes. In this case study, a Steam Assisted Gravity Drainage (SAGD) facility in northern Alberta, Canada is examined as it experienced two very similar failures in heat exchanger tubes within 2 years of each other due to a boiler feedwater (BFW) tank without a nitrogen blanket and a low flow condition. High amounts of oxygen were able to dissolve into the BFW, which led to several problems downstream of the BFW tank, particularly in the tubes of the heat exchangers. The low flow conditions present in the system led to a buildup of solids, which also aided in an accelerated corrosion rate.

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
