Wellbore Sinuosity and Its Effect on Production and Recovery from Horizontal Wells Along the Cummings/Dina Channel Trend in Senlac and Winter Saskatchewan
Bibliographic record
Abstract
Abstract Over 500 horizontal wells have been drilled into the Cummings/Dina channel trend between Senlac and Winter since 1990. These wells produce 13 – 14 API oil with a gas free viscosity of 3600 cp from a depth of 700 meters. Production peaks at about 20 to 60 m3/d oil with 10% water and 1.5% sand. Oil production eventually declines as water cut increases. Sanding events can limit oil production rates and recovery. Wellbore trajectory control has improved significantly in the last 10 years, the latest improvement being ‘inclination at the bit.’ Selected wells were analyzed to determine the key factors between sinuosity and production rate and ultimate recovery, and the changes in the effect of these key factors over the last 10 years. Incentive and methodology for development of current flatter wells is discussed, and predictions for production from current flatter wells are given.

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.
