Case Study on Hayter Heavy Oil Pool Update, Alberta: Reducing Risk and Increasing Recoveries for Economic Heavy Oil Horizontal Well Placement
Bibliographic record
Abstract
Abstract Systematic approach and detailed integrated geo-modelling work with reservoir engineering processes has yielded additional economic locations to an already mature development within a Section of land at 26-40-1W4 in the Alberta side and the border with Saskatchewan. The pool currently produces about 2700 BOPD of oil; it was near its economic life back in 2003. Current well density is less than 4 acres, making it one of the most densely drilled Sections in Alberta. About 10 horizontal wells per year are drilled within the Heavy Oil pool in the last 8 years. The 12-16m sand is underlain by an active bottom water drive system. The 16 API oil pool recoveries have increased from about 17% to 25% so far. The update will show how detailed understanding of oil in place, recovery mechanism and correct prediction of the conning through a geo-model as well as solutions to incorporate collision avoidance has resulted in near 100% success in the past 9 years.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
