Abstract
The goals of this work are (1) to evaluate the impact of Discrete Fracture Networks (DFN) upscaling methods on new wells placed in the simulation model and (2) to develop a well representation proposal of new wells in naturally fractured reservoirs simulation models. Three DFN permeability upscaling methods (Oda, Oda Corrected, and Flow-based) are used at three model scale fidelities (high, medium-high, and medium). The results suggest more uncertainty of well-dynamic data in medium fidelity models. Our reference case is defined as the combination of fidelity scale and upscaling method that produces less variation in well-dynamic data. This results in a model constructed with a high-fidelity scale and Flow-based method (linear pressure). The proposed well representation suggests substituting the well index in the matrix and fracture systems of the medium-fidelity model with the reference model’s WI. We show the necessity of this correction with a field-scale application.

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 it
