Abstract

fetched live from OpenAlex

Abstract The Alberta Energy Regulator (AER) has recently put a moratorium on shallow SAGD developments pending a review of technology. They have also sent out a series of draft requirements while the moratorium is in effect. This response has been to a series of events that have occurred and a growing requirement for environmental stewardship. The objective of the paper is to provide a history of what events have occurred, where the new requirements are taking the industry and a brief discussion of the implications. The first part of the paper will discuss a broad background of incidents that have occurred in Alberta with thermal projects. A brief description will be made of the main technical issues in calculating caprock integrity. The government has issued 5 separate documents that cover different aspects. A more detailed review will be outlined. Although the discussion is centered on thermal developments, caprock integrity is of broad concern in underground storage and unconventional reservoir development which utilizes multi-stage hydraulic fracturing. Government requirements are rapidly changing and it is a real challenge to keep up with these changes. Some comment will be made on how the caprock issue will likely develop over the next few years.

Full frame distilled prediction

Teacher imitation

Not 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.
