Abstract
Abstract Heavy oil production has enjoyed a resurgence as both major and junior operating companies diversify their portfolios and pursue new opportunities. The key factors for the renewed interest are:Improved profitabilityTechnological advances have improved productivityEnormous reserve sizeLow geological riskLow capital investment required for non-thermal projects In addition, immediate concerns about environmental issues such as sand disposal and gas migration appear to have been resolved to the extent that there is no immediate threat to the operating environment. The key risk factors remain oil and gas prices, land prices, and economic means of sand disposal. This paper focuses on "cold production" as one of the most attractive new technologies used to produce heavy oil in the Lloydminster area. Steam assisted gravity drainage (SAGD) will be the focus of a future paper. Introduction Western Canadian crude oil production is approximately 320,000 m3/d. Of this amount, 50﹪ is comprised of heavy crude and bitumen. While bitumen demand has been essentially flat since the mid- to late-1980s, heavy oil production has doubled from 56,000 m3/d to 112,000 m3/d in the last ten years(1). Why Heavy Oil?

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 it
