Abstract
Accurate identification of fractures is necessary and complex for carbonate reservoir exploration. Using conventional well logs and geological data, we identify various fracture identification methods based on depth point information and waveform processing. The results show that the method based on equivalent medium theory maintains high stability and accuracy in reflecting the secondary pores in cases of unfavorable borehole environments. Both the acoustic log and dual lateral difference fractal dimensions increase in line with the degree of fracture development. The high-frequency energy information shows significantly high values in the fractured zone on a suitable scale. Finally, the fractures are characterized by a novel approach based on feature fusion. The linear predictive relationship for fracture identification via proposed comprehensive factor scores (CFS) avoids the influence of the deviation of a few variables on the stability of the overall results. Our study offers a new framework for fracture identification in the exploration and evaluation of carbonate reservoirs.

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
