Abstract
Summary Processes like cyclic steam injection, hydraulic fracturing... are used to increase the permeability of oil and gas reservoirs or geothermal fields. Microseismic events are created during these processes at the injection point due to the local stress changes induced by fluid pressure. The location of events can reveal pre-existing structures whose shape was determined by surrounding tectonic stresses, and weak planes within rocks. The spatial distribution of events is quantified by the D-value, a statistical coefficient which reflects the clustering of events. Source properties of microseismic events can be retrieved through the fractal dimension which describes the frequency-magnitude distribution of the events, also known as b-value. A combined statistical study of these two dimensions can help infer the variations of local stresses in a reservoir.

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
