However, these long open hole horizontals are often problematic when using coiled tubing as the well intervention conveyance system during stimulation.Coiled tubing, a commonly used intervention tool for open hole horizontals, is considerably less stiff than jointed drill pipe and cannot reach TD on many wells due to friction. Assistance from friction reducers, well tractors or other devices have helped, but can be potentially damaging, expensive and/or high risk.This poster details the use of a simple agitation tool placed in the coiled tubing bottom hole assembly during the stimulation. This results in decreased friction which in turn increases reach for coiled tubing thereby allowing full horizontal open hole stimulation treatment.The case study that is presented on the performance of the agitation tool used in coiled tubing stimulations in long horizontal open hole sections of a hot, sour reservoir with a total measured depth up to 7 kilometers.Suncor Energy has utilized this process in the development of its Panther River reservoirs in the Western Canadian Sedimentary Basin with excellent results. Benefits discussed include reduced completion cost and reduced environmental impact.

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.
