Comment on "Potential for environmental impact due to acid gas leakage from wellbores at EOR injection sites near Zama Lake, Alberta" by D.M. LeNeveu (2012)
Bibliographic record
Abstract
This comment concerns the potential hazards identified by LeNeveu 1 concerning acid gas injection at the Zama Lake oil and gas field in northwestern Alberta.Acid gas is injected both as an enhanced oil recovery method and for geologic disposal.The results found by LeNeveu 1 suggest a high likelihood for serious and widespread release of H 2 S by leakage through wellbores.We critically examine LeNeveu's 1 assumptions regarding well leakage response, wellbore seal degradation, and wellbore permeability, and identify more realistic and defensible assumptions.Utilizing these more credible assumptions leads to expectations for greater atmospheric dispersal and reduced acid gas leakage rates as compared to the findings by LeNeveu 1 .

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
