Abstract
Resume — La production froide de certains reservoirs contenant des huiles visqueuses, au Canada et au Venezuela principalement, amene a des productivites et des taux de recuperation superieurs aux predictions calculees a l’aide des equations habituellement utilisees pour decrire les ecoulements classiques. Pour expliquer ces productions anormalement elevees, un certain nombre de mecanismes ont ete evoques, principalement d’origines hydrodynamiques et geomecaniques. Les proprietes hydrodynamiques des fluides produits, partiellement degazes durant la production : huiles moussantes, fluides a bulles, sont en effet plus favorables que celles des fluides en place. Par effet geomecanique d’erosion interne du sable, un reseau de chenaux (wormholes, piping tubes) peut se creer in situ, ameliorant notablement le drainage. Cet article comprend quatre parties : les observations sur champ, l’etude en laboratoire des huiles moussantes, leur modelisation numerique, les effets geomecaniques lies a la production de sable. Mots-cles : production froide, huile lourde, huile visqueuse, production de sable, wormholes.

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.
