Abstract
Abstract The Cretaceous Cardium formation has been produced since the early 1950’s. The Cardium is a sandstone that can exhibit a wide range in permeability. This is due to the diversity of the depositional environment creating deposits that can vary from siltstone, fine grained sandstone to conglomerate. The formation is laterally extensive across western Alberta. Secondary recovery in the form of water flooding has been ongoing in the core area since the 1960’s allowing production into the twenty first century. However, it wasn’t until the application of horizontal drilling and multi-stage completion techniques that the vast reserves in the poorer quality areas could be economically produced. This paper discusses the initial phase of an optimization process used to increase production and net present value in Cardium completions through the application of reservoir modeling, optimized fracture spacing and the application of a solids-free viscoelastic fracturing fluid. The new approach provides higher production rates and accelerated flowback compared to the gelled oil system previously employed. In addition to the previous two points, the economics are further enhanced by the elimination of the substantial cost of oil used in gelled oil stimulations.

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 it
