In Situ Coal Gasification As An Alternative For Natural Gas In The Bitumen Extraction And Upgrading Processes In Alberta
Bibliographic record
Abstract
Alberta has significant coal resources, which represent a major potential for syngas and hydrogen production using underground coal gasification (UCG). Natural gas production in the province is decreasing while demand continues to rise, driven by high demand of this product in the oil sands. This project analyzes the convenience of using syngas from UCG as a substitute for natural gas in Steam Assisted Gravity Drainage and hydrogen production in the hydrocracking process during bitumen upgrading. A major finding of this research project is that ground water risks, fresh water usage and greenhouse gases from the UCG process can be reduced when coal is gasified in deep formations. Syngas as fuel is not economically feasibility under current natural gas price but hydrogen production could be a good alternative for steam-methane reforming under current natural gas price. Strategy analysis shows that oil and gas companies have a strong competitive advantage to develop UCG projects over conventional coal companies.

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.
