Controls on Mannville Coalbed Methane Production in Fort Assiniboine, Alberta
Bibliographic record
Abstract
Abstract Fort Assiniboine is a commercial Coalbed Methane field in central Alberta, Canada with over 200 multilateral horizontal wells in the Upper Cretaceous Mannville coal. The Mannville coal seams in this area are under-saturated. Therefore the reservoir's ability to dewater the coal through the fracture fabric to establish a gas phase is key to improving permeability to gas within the fracture system and thus achieving economic gas production rates. There is a wide range of production rates seen across the field. The multiple variables that affect gas production can be divided into a two main categories, wellbore parameters and reservoir parameters. Some of these variables were sufficiently straightforward to establish while other variables, such as permeability, are not as easily ascertained in a fractured coal system having multiphase flow. Field wide data was collected from core, wells, geological and geophysical mapping and production data. The information was compiled and analyzed in order to determine the major controls on gas production rates.

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.
