Abstract

fetched live from OpenAlex

Two of the most active areas of current geophysical research and development involve depth imaging and velocity anisotropy. This is fitting, given that the potential benefits of the former may be fully realized only if the latter is appropriately taken into account. It is well established that depth images depend on the accuracy of the velocity model (Zhu et al., 1998; Parkes and Hatton, 1987). If anisotropy is present and not accounted for in velocity model building and migration, the final image will be incorrect, giving rise to mispositioned and/or false structures (Isaac and Lawton, 1999; Vestrum et al., 1999) and hence increasing the risk of dry holes. It is therefore important to determine which formations exhibit seismic anisotropy and to quantify their anisotropy parameters.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
