Abstract

fetched live from OpenAlex

The vast heavy oil and far sands resources in Canada, Venezuela, the United States and other parts of the world will remain largely underutilized, unless more economic means are found to upgrade them to higher quality oil stocks. Surface upgrading processes, or Stage I Technol., incur high costs because of the investment needed in thermal coker plants and assocd. hydrogen generation plants. Included also in this category, is the higher conversion hydroconversion processes, which operate at much higher temps. and pressures. Here, the initial capex required is very large, around $3 billion for a 200,000 bbl/day capacity unit. Advanced in situ processes, incorporating high recovery and catalytic upgrading steps, are a potential route to more efficient, more economic Stage II technol. [on SciFinder (R)]

Not 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.
