Pilot Testing of a New Generation of Induced Gas Flotation Equipment
Bibliographic record
Abstract
Summary Induced gas flotation (IGF) technology is well-known in the oil industry for effectively treating produced water to meet environmental oil-in-water discharge requirements. This paper presents technical considerations for development of a new generation of IGF units, a discussion of the process kinetics, actual operating data, and performance analysis of a full-sized, four-cell WEMCO* cylindrical depurator. A pilot test program was developed and executed in collaboration with ChevronTexaco Overseas Petroleum on platformgathering-station Mike, located offshore in the Cabinda Province, Angola. Pilot data indicate that the flotation kinetic rate for oil removal from a four-cell cylindrical depurator is comparable with a conventional depurator. Cylindrical depurator design captures the main technical advantage of conventional, mechanical IGF units for effective oil-particle flotation and offers the promise of fewer maintenance issues as well as viable alternatives for higher-pressure applications. Field data validate theoretical predictions for the performance of the cylindrical depurator.

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.
