Effect of Iron Oxidizing Bacteria Biofilm on Corrosion Inhibition of Imidazoline Derivative in CO<sub>2</sub>-Containing Oilfield Produced Water with Organic Carbon Source Starvation
Bibliographic record
Abstract
In this work, corrosion of a Q235 carbon steel in CO2-containing oilfield produced water in the presence of iron oxidizing bacteria (IOB) with organic carbon source starvation and the inhibiting performance of imidazoline derivative were investigated by weight loss, electrochemical measurements and surface analysis techniques. Results show that iron oxidizing bacteria (IOB) could survive well in the aqueous environments with organic carbon source starvation. Corrosion of the steel occurred under the IOB biofilm. Both the planktonic and sessile IOB cell counts after 14 days of testing were related to the biofilm incubation time. The corrosion rate of the steel covered with 7-day IOB biofilm was lowest suggesting that this biofilm had the weakest corrosivity in the test solution. The inhibition performance of the inhibitor was affected by the IOB biofilm formed on steel surface. There was a higher inhibition efficiency of the inhibitor, when the steel was covered with a 2-day IOB biofilm due to less IOB biofilm formed on the steel.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
